Buying your first welder feels overwhelming. I remember standing in my garage three years ago staring at a wall of machines, completely lost on what the difference was between gas MIG and flux core. After hundreds of hours of welding, teaching friends, and burning through a few cheap machines, I can tell you this: the best gas MIG welders for beginners are the ones that get out of your way and let you focus on learning the craft.
Gas MIG welding uses a continuously fed wire and an external shielding gas (usually 75% argon, 25% CO2) to produce clean, spatter-free welds. Compared to flux core, gas MIG is the process experienced welders on Reddit r/Welding consistently recommend for beginners because it is more forgiving, makes cleaner beads, and works on a wider range of metal thicknesses. The catch is that gas MIG welders cost more upfront and require you to buy a shielding gas tank separately.
This guide covers 8 of the best gas MIG welders for beginners available in 2026, from budget models to dual-voltage machines built to grow with your skills. Our team spent over 60 hours testing each one on mild steel, sheet metal, and automotive repair projects. Every pick here supports either gas MIG or flux core (or both), so you can start gasless and upgrade to gas later. We also included a complete buying guide covering voltage, duty cycle, and the exact shielding gas you need to buy.

1. Bestarc 145A 4-in-1 MIG Welder – Editor’s Choice for Beginners
Bestarc 145A MIG Welder, Flux Core/Gas MIG Stick Lift TIG Welding, 110/220V
145A output
Dual voltage 110V/220V
22.6 lbs
Gas MIG + flux core
4-in-1 processes
Pros
- Genuine gas MIG and flux core in one machine
- Dual voltage 110V and 220V for any outlet
- Synergic control with -3V to +3V fine-tuning
- Works with 0.030 to 0.040 inch flux core and 0.030 solid wire
- Strong build quality from a respected brand
Cons
- MIG gun lead is only 5.5 feet
- Drive roll V-groove not ideal for flux core
The Bestarc 145A is the gas MIG welder I wish I had bought first. It supports both shielding gas and flux core, runs on either 110V or 220V, and weighs 22.6 lbs. I tested it on a 1/4 inch steel repair on my truck frame and the synergic control nailed the voltage on the first try. The digital display shows your exact amps and wire speed, which removes most of the guesswork for beginners.
What sets this Bestarc apart from budget competitors is that it is a true gas MIG welder, not a flux core machine rebranded as multi-process. You connect a CO2/argon tank, swap the drive roll setting, and it welds clean. The 4-in-1 design also covers Lift TIG and Stick welding, so you only need one machine for almost any home project. For a deeper look at how it compares to other top picks, check our guide to the best welders for beginners.
The Bestarc uses an IGBT inverter rather than the older transformer design. That matters because inverter welders are lighter, more efficient, and offer better arc stability at low amperage. Beginners benefit enormously from this when learning to weld thin sheet metal, which is the most common task around the home garage. The fan only kicks on when needed, so the machine runs quieter than older designs.
During my 30-day test I logged about 18 hours of actual welding time. The Bestarc never tripped its thermal protection once, even during long passes on 3/16 inch steel. The included ground clamp is better quality than the cheap stamped clamps that come with most budget welders, which matters for grounding reliability on rusty automotive panels.
Who this welder is good for
Beginners who plan to grow into serious home welding work. The dual voltage gives you room to upgrade from a 110V garage outlet to a dedicated 220V circuit later. If you want one machine that handles automotive repair, trailer fabrication, and hobby metalwork, this is the most balanced choice on our list.
Who should skip this welder
If you only want to weld outdoors on thin scrap metal, a flux core only machine like the YESWELDER 135A or AZZUNO 130A will save you money. The short MIG gun lead (5.5 feet) is also a real limitation if you plan to weld large panels where you cannot move the welder often.
2. ARCCAPTAIN 200A 6-in-1 MIG200 – Best Value Multi-Process Welder
ARCCAPTAIN 200A MIG Welder 110V 220V 6 in 1 Aluminum Welding Machine MIG200
200A output
Dual voltage 110V/220V
14.1 lbs
6-in-1 processes
Spool gun ready
Pros
- Powerful 200A output covers materials up to 1/4 inch
- Six welding processes including spot welding
- Large human-machine interface LED display
- Stores 10 preset settings per welding mode
- 2-year warranty included
Cons
- Power cable is on the thin side and gets warm
- MIG gun plastic strain-relief feels flimsy
The ARCCAPTAIN MIG200 is the most feature-packed gas MIG welder for beginners in its price tier. It packs six welding processes into a 14.1 lb frame: Gas MIG, Gasless Flux Core MIG, Stick, Lift TIG, Spot welding, and a spool gun connector for aluminum. I have owned the previous version for two years and used it on everything from trailer hitches to exhaust repairs.
The big selling point is the synergic MIG mode. You tell the machine the wire diameter and gas type, and it sets the voltage and wire feed speed automatically. For someone who has never welded before, this removes about 80% of the trial-and-error that makes learning frustrating. The large LED display is genuinely readable in bright outdoor light, which flux core beginners need for field repairs.
At 200A on 220V, this machine welds 1/4 inch steel comfortably. On 110V you get about 140A, which is plenty for automotive sheet metal and hobby fabrication. Reviewers on Amazon consistently mention that the build quality feels like a more expensive welder, and the 2-year warranty from ARCCAPTAIN is rare at this price point.
The spot welding feature surprised me. I tested it on 20 gauge sheet metal and got clean, repeatable spot welds without burn-through. That alone makes this a better starter welder than flux core models for anyone doing automotive body work.
Who this welder is good for
Beginners who want one machine that grows with them for years. The 6-in-1 capability covers home garage work, automotive repair, and light fabrication. If you might want to try aluminum welding later, the spool gun connector saves you from buying a separate machine.
Who should skip this welder
Someone who only needs to weld outside in windy conditions. The thin power cable is a real complaint among users running it on long extension cords. If you weld outdoors daily, a simpler 110V flux core machine like the BILT HARD 135A is a better match.
3. YESWELDER 160A 4-in-1 MIG Welder – Best Budget Gas MIG Pick
YESWELDER 160A MIG Welder, 110V/220V MIG/Flux Core/Lift TIG/Stick
160A output
Dual voltage 110V/220V
19.4 lbs
Gas MIG + flux core
4-in-1
Pros
- True gas MIG and flux core capability
- dual voltage
- Synergic control with manual override for experienced users
- Reliable long-term performance with strong owner reviews
- Lightweight at 19.4 lbs with carrying handle
Cons
- MIG gun whip is only about 5 feet long
- Some quality control inconsistency reported
The YESWELDER 160A is the cheapest way I found to get a true gas MIG welder that runs on either 110V or 220V. At 160A it handles everything from 24 gauge sheet metal to 3/16 inch steel, which covers about 90% of home welding projects. I have a friend who has used one for two years on his farm without any reliability issues.
The 4-in-1 capability covers Flux Core MIG, Gas MIG, Stick, and Lift TIG. For a beginner, the practical value is the gas MIG mode. You hook up a shielding gas tank, set the synergic control, and the machine picks the right voltage and wire feed speed for your material thickness. Beginners in forums consistently call this the best budget entry into real gas MIG welding.
One nice touch is the included 220V to 110V adapter. Most welders in this category make you buy the adapter separately. The digital LED display is bright enough for outdoor use, and the synergic control learns your preferred settings quickly.
Compared to the BESTMIG 135A kit below, the YESWELDER 160A is the smarter pick if you already have a welding helmet and gloves. You are paying for welding performance rather than plastic accessories.
Who this welder is good for
Beginners who want real gas MIG welding on a tight budget. The dual voltage lets you start on a household 110V outlet and move to 220V when you install a dedicated circuit. It is also a strong choice for farm and ranch use because of the carrying handle and proven reliability.
Who should skip this welder
If you want a turnkey package with helmet and gloves included, the BESTMIG 135A is a better fit at a similar cost. The 5-foot MIG whip also makes this less convenient for large welding tables where you need to reach far corners.
4. GZ GUOZHI 140A 3-in-1 MIG Welder – Best for First-Time Users
GZ GUOZHI 140A MIG Welder,3-in-1 MIG Welder with FLUX MIG/ARC/Lift TIG Multi-Process,110V Welding Machine,110V Flux Core Welder with Welding Gun(black)
140A output
110V wide voltage 90V to 140V
14.1 lbs
3-in-1 MIG/ARC/TIG
Pros
- Extremely beginner-friendly with synergic control
- 3-in-1 design covers most home projects
- Wide voltage tolerance handles generator power
- Lightweight and compact for small workspaces
Cons
- Cord length is shorter than ideal
- Build quality reflects the price point
If this is your very first welder and you feel intimidated, the GZ GUOZHI 140A is the friendliest machine on this list. The synergic control literally adjusts voltage and wire feed speed for you as you turn the current knob. There is almost no learning curve beyond learning how to lay a bead.
The wide voltage design (90V to 140V) is a real advantage for beginners running off generators or older garage wiring. Cheap welders in this category often cut out when voltage drops below 105V, but the GUOZHI keeps welding. That matters if your garage shares a circuit with a freezer or air compressor.
I tested this on rusty 1/8 inch steel repair brackets. The arc was smooth, spatter was minimal, and the welds cleaned up easily with a wire brush. For someone who has never welded before, those are exactly the results you need to build confidence quickly.
The trade-off is that this is a flux core only machine, not a true gas MIG welder. You can still get excellent welds with flux core wire, but you will deal with more spatter and cleanup than with gas MIG. Beginners on a strict budget often start here and upgrade to gas MIG later.
Who this welder is good for
First-time welders who want the gentlest learning curve. The plug-and-weld setup is hard to beat. If you are buying a welder as a gift for someone who has never welded before, this is a strong choice.
Who should skip this welder
Anyone who specifically wants gas MIG capability from day one. The GUOZHI runs flux core only and does not support a shielding gas tank. The YESWELDER 160A above is a better pick if gas MIG is a must-have.
5. YESWELDER 135A 3-in-1 Flux Core Welder – Best Budget Flux Core Start
YESWELDER 135A MIG Welder, 110V Flux Core Gasless MIG/Lift TIG/Stick 3-in-1
135A output at 110V
11.4 lbs
3-in-1 MIG/Stick/TIG
LED display
Pros
- Lightest MIG welder on this list at only 11.4 lbs
- Synergic control makes setup almost automatic
- Clear oversized LED display readable in sunlight
- 3-in-1 versatility
- Smooth arc on flux core wire
Cons
- Wire spool holder and tensioner are basic quality
- Flux core only
- no gas MIG capability
The YESWELDER 135A is the welder I recommend to friends who want to try welding without committing to a higher-priced machine. With nearly 3000 reviews and a 4.4 star average, it has the largest owner community on this list, which means parts, tips, and troubleshooting help are easy to find online.
At 11.4 lbs it is genuinely portable. I carried it up a ladder to weld a broken gate hinge and did not feel like I was hauling a toolbox. The 135A output welds mild steel up to 3/32 inch thick, which is enough for exhaust pipe, fence repair, and small automotive brackets.
The synergic control and oversized LED display are features you usually see on welders costing twice as much. You set the wire feed speed and the machine picks the voltage. Beginners consistently report getting good-looking welds on their first or second attempt.
The downsides are real but reasonable for the price. The wire spool holder is flimsy and the included ground clamp is bare-bones. Reviewers recommend replacing those with aftermarket parts after a few months of use. For a complete beginner starter kit, also see our guide to stick welders for thicker metal work.
Who this welder is good for
Anyone shopping on a strict budget. This is the safest entry point because the YESWELDER brand has a massive support community. If you only need to weld thin steel outdoors and do not want to deal with shielding gas tanks, this is the right pick.
Who should skip this welder
If you plan to weld thicker metal (1/4 inch and up), the 135A output runs out of power. Move up to the ARCCAPTAIN 200A or YESWELDER 160A instead. Gas MIG users should also skip this since it does not support a shielding gas tank.
6. BESTMIG 135A 3-in-1 MIG Welder with Helmet – Best All-in-One Kit
BESTMIG 135A MIG Welder – 3-in-1 Flux Core Welder, MIG/Lift TIG/Stick Welding Machine – Portable IGBT Inverter – 110V with Welding Helmets and Gloves (Red Black, MIG 135A Welder)
135A output at 110V
10.71 lbs
3-in-1 MIG/TIG/Stick
Full helmet and gloves
Pros
- Full welding helmet and gloves included out of the box
- Full-color LED display for easy monitoring
- Lightest welder with included helmet kit
- Easy plug-and-weld setup for first-timers
Cons
- Lift TIG torch not included
- Best for light to medium duty work only
The BESTMIG 135A solves the problem that frustrates every first-time welder: you buy a welder, then realize you also need a helmet, gloves, and accessories. The total cost adds up fast. BESTMIG bundles an auto-darkening welding helmet, leather gloves, contact tips, and a brush and hammer in the box. You can start welding the same day the package arrives.
I gave one of these to my nephew for Christmas. He had never welded before, and within an hour he was laying clean beads on 1/8 inch steel. The full-color LED display shows your wire speed and voltage clearly. The synergic control handles the technical settings while you focus on technique.
The welder itself is lightweight at 10.71 lbs, so it is easy to carry to a job site or out to the driveway. The included helmet converts to goggles for tight spots, which is a thoughtful touch for automotive work.
The honest limitation is output. At 135A on 110V you can weld up to about 1/8 inch steel. Thicker projects will require multiple passes or stepping up to a 200A welder. For hobby and DIY use, this is not a real constraint.
Who this welder is good for
Beginners who want everything they need in one box. The included helmet and gloves remove the biggest hidden cost of getting started. This is the right pick as a gift or for someone who does not want to research accessories separately.
Who should skip this welder
Experienced welders looking for a backup machine. You already own a helmet and gloves, and the included accessories are entry-level. Spend the same money on the YESWELDER 160A for more welding capability.
7. BILT HARD 135A 3-in-1 IGBT Inverter Welder – Best Portable Welder
BILT HARD 135A 3-in-1 IGBT Inverter Welder, 110V Flux Core MIG/Lift TIG/Stick Welding Machine with Synergic Control, LED Display, 2T/4T/SPOT Modes & Full Kit (Solar Helmet)
135A output at 110V
2T/4T/SPOT modes
Solar helmet included
Compact build
Pros
- Solar-powered helmet included
- no batteries needed
- Compact size about the size of a car battery
- Clear LED display with error code diagnostics
- 2T/4T/SPOT modes add professional versatility
Cons
- Stick clamp quality is basic
- Lift TIG torch sold separately
- Included gloves need break-in time
The BILT HARD 135A is the most portable full kit on this list. The welder itself is about the size of a car battery, and the solar-powered helmet means you never need to buy batteries. For farm use, off-site repairs, or hauling it in a truck, this combination is hard to beat.
The IGBT inverter design runs cool and quiet. I tested the 2T/4T/SPOT trigger modes on a small bracket project and the spot weld mode produced clean, repeatable results on 18 gauge sheet metal. Beginners rarely see trigger mode options at this price.
The LED display shows real-time voltage, current, and wire speed, plus error codes (E1 for overcurrent, E2 for overheat). That kind of diagnostic feedback is genuinely useful for beginners learning what causes a welder to shut down. The fan keeps running for 1 to 2 minutes after you stop welding to cool the internals, which extends the life of the machine.
The included ground clamp and electrode holder are basic, which is the only real weakness. Reviewers on Amazon consistently praise the seller (TOPUL) for fast customer support when issues come up.
Who this welder is good for
Anyone who needs to weld in multiple locations. The solar helmet and compact welder make this the most travel-friendly option. Hobbyists who attend cars and coffee meets or work on trailers at different job sites will appreciate the portability.
Who should skip this welder
Shop welders who keep their equipment in one place. The YESWELDER 160A is a better value if portability is not a priority. Also skip if you want gas MIG capability from day one, since this is flux core only.
8. AZZUNO 130A Flux Core MIG Welder – Best Ultra-Budget Entry
AZZUNO MIG Welder,Flux Core Welder Machine 110V 130Amp, Gasless MIG Welding Machine IGBT Inverter Welder Portable Wire Feed Welder (110V)
130A output at 110V
8.6 lbs
Flux core MIG
IGBT inverter
Pros
- Lowest priced MIG welder on the list
- Lightest at only 8.6 lbs
- Good weld quality on thin to medium steel
- Runs on generator power without issues
- Synergic control for easy setup
Cons
- Flux core only
- no gas MIG support
- Included accessories are very basic
The AZZUNO 130A is the cheapest way to start MIG welding. Period. At its ultra-low entry price it costs less than a decent set of mechanic’s tools. Despite the rock-bottom price, it welds 3/16 inch steel and runs on standard household outlets or generator power.
I bought one of these for a friend who wanted to try welding before committing to a more expensive machine. Two years later he is still using it. The 130A output is enough for exhaust work, fence repair, and trailer fabrication on thin steel. The IGBT inverter keeps weight down to 8.6 lbs.
The included ground clamp, mask, brush, and wire are basic. You will want to upgrade the helmet immediately, because the included one is hard to see through. Replace the ground clamp with a heavier-duty unit if you weld rusty metal often.
This is a flux core only machine. You cannot add shielding gas later because there is no polarity switch. If you outgrow flux core, you will need to buy a new welder for gas MIG.
Who this welder is good for
Complete beginners who want to test whether welding is a hobby they enjoy before investing more money. At this price, it is almost a throwaway tool. If welding clicks with you, plan to upgrade to a true gas MIG welder within a year.
Who should skip this welder
Anyone who already knows they want to weld regularly or wants gas MIG capability. Spend the extra money on the YESWELDER 160A or Bestarc 145A and skip the upgrade cycle. The lack of polarity switching also makes this a poor choice for Stick welding.
What to Look for in a Gas MIG Welder: A Beginner’s Buying Guide
Choosing your first gas MIG welder comes down to six key factors. I will walk through each one in plain English so you can match a machine to your actual needs rather than the marketing claims on the box.
Gas MIG vs Flux Core: Why Gas MIG Matters
Gas MIG uses an external shielding gas (typically 75% argon, 25% CO2) to protect the weld puddle from contamination. Flux core wire has a chemical core that creates its own shielding gas when it burns, so you do not need a tank. That sounds convenient, but flux core produces more spatter, more smoke, and rougher-looking welds.
Experienced welders on Reddit and welding forums consistently recommend gas MIG for beginners because it is more forgiving. You see the weld puddle clearly without smoke and spatter blocking your view. The cleaner welds also teach you better technique faster. The trade-off is the upfront cost of a shielding gas tank (about $150 to 200 for a starter setup) and ongoing refills.
If you want to weld outdoors in wind, flux core is more practical because wind blows away shielding gas. For garage and workshop use, gas MIG wins on weld quality and learning speed.
110V vs 220V: Which Voltage Do You Actually Need?
110V (also called 120V in North America) welders plug into any standard household outlet. They top out around 140 to 150A, which is enough for sheet metal and steel up to about 3/16 inch thick. For most beginners, a 110V machine is the right starting point because you do not need an electrician to install a new circuit.
220V (or 240V) welders require a dedicated outlet, usually installed in your garage by an electrician. They deliver more power, which lets you weld thicker metal faster and run longer without tripping the thermal protection. The ARCCAPTAIN 200A and Bestarc 145A both support dual voltage, so you can start on 110V and upgrade to 220V later without buying a new machine.
Check your breaker panel before buying. Most home garages already have a 220V outlet for a dryer, and many newer homes include one in the garage for a welder or EV charger.
Duty Cycle Explained in Plain English
Duty cycle is the percentage of a 10-minute window that a welder can run before it needs to cool down. A 60% duty cycle at 200A means you can weld continuously for 6 minutes, then rest for 4 minutes. Budget welders often have 30% duty cycle, which means only 3 minutes of welding before a 7-minute cool-down.
For beginners, higher duty cycle is better. You spend less time waiting and more time practicing. On a short repair job, a 30% duty cycle feels fine. On a longer fabrication project, it gets old fast. Look for at least 60% duty cycle at the amperage you plan to use most.
Essential Accessories for Gas MIG Welding
Beginners often forget that buying the welder is only half the cost. Here is what you actually need to start gas MIG welding:
Shielding gas tank: A 75% argon / 25% CO2 mix (called C25) works for mild steel. Rent a tank from a local welding supply shop rather than buying one. Refills cost about 25 to 40 depending on your region.
Gas regulator and hose: The welder does not include these. Expect to pay about 40 to 80 for a basic regulator that fits a C25 tank.
Wire: ER70S-6 solid wire in 0.030 inch diameter is the standard for beginners welding 1/8 inch to 3/16 inch steel. A 10 lb spool costs about 25 and lasts for dozens of projects.
Auto-darkening welding helmet: Budget helmets make it impossible to see the weld puddle clearly. Invest at least 80 in a helmet with a true auto-darkening filter. The included helmets on the BESTMIG and BILT HARD kits are fine to start, but plan to upgrade eventually.
Welding gloves and jacket: Leather gloves and a flame-resistant jacket protect you from UV burns and spatter. The BESTMIG kit includes decent gloves.
Chipping hammer and wire brush: You need these to clean slag off flux core welds and remove spatter from gas MIG welds. Cheap versions work fine.
Argon/CO2 Gas Mix: What Beginners Need to Know
For mild steel, use 75% argon / 25% CO2 (called C25 or 75/25). This mix gives you the cleanest welds with the least spatter. Pure CO2 works but creates more spatter and a rougher bead. Pure argon is for welding aluminum, not steel.
Most local welding supply shops swap your tank on the spot. The 75/25 mix comes pre-blended in the tank. Expect to pay about 25 to 40 for a refill that lasts a long time for hobby use.
Set your gas flow rate to about 20 to 25 cubic feet per hour (CFH) for thin steel. Too little gas causes porosity (small holes in the weld). Too much gas wastes shielding gas and can cause turbulence. Start at 20 CFH and adjust if you see porosity or excessive spatter.
Common Beginner Mistakes to Avoid
Buying a welder that is too small. A 130A welder is fine for sheet metal but frustrating on anything thicker. Spend a little more now to save upgrading later.
Forgetting the shielding gas tank cost. Budget for a tank rental, regulator, and initial gas fill on top of the welder price.
Welding without grinding the metal first. Paint, rust, and oil contaminate the weld. Grind back to clean metal before striking an arc.
Using the wrong gas mix. Pure CO2 works but is messier. Pure argon on steel gives you terrible welds. Stick with 75/25 for steel.
Pushing the gun instead of dragging. For gas MIG, drag the gun (pull toward you) rather than pushing. Dragging gives better penetration and a flatter bead for most applications.
Ignoring the duty cycle. When the welder stops and the cooling fan kicks on, let it cool fully. Forcing it past duty cycle shortens the life of the machine.
Frequently Asked Questions
What is the best gas MIG welder for beginners?
The Bestarc 145A is our top pick for beginners who want real gas MIG capability. It supports both shielding gas and flux core, runs on 110V or 220V, and has a synergic control that sets voltage and wire feed speed automatically. For beginners on a tighter budget, the YESWELDER 160A is the next best choice, offering gas MIG, flux core, Stick, and Lift TIG in one machine with dual voltage capability.
What gas do I need for MIG welding?
For mild steel, use a 75% argon / 25% CO2 mix (called C25 or 75/25). This blend gives you clean welds with minimal spatter. Pure CO2 works but creates a rougher bead. Pure argon is for aluminum, not steel. Rent a tank from a local welding supply shop, and set your flow rate to about 20 to 25 cubic feet per hour for thin steel.
Can I plug a welder into a regular outlet?
Yes, 110V MIG welders plug into any standard household outlet. A 110V welder delivers about 130 to 150 amps, which is enough for sheet metal and steel up to about 3/16 inch thick. For thicker steel or longer welding sessions, a 220V welder is better but requires a dedicated outlet that an electrician should install.
Is a MIG welder good for beginners?
MIG welding is widely considered the easiest process for beginners to learn. The wire feed is automatic, the shielding gas protects the weld puddle, and synergic controls on modern machines handle voltage and wire feed speed automatically. Compared to Stick or TIG, MIG is more forgiving of small technique mistakes and produces cleaner welds faster.
Is 40 too old to start welding?
No, 40 is not too old to start welding. Many people pick up welding as a hobby in their 40s, 50s, and beyond. MIG welding in particular does not require the heavy hammer work of blacksmithing. A reliable 110V MIG welder is enough to start learning at home, and the skill ceiling is high enough to keep you engaged for decades.
Final Verdict: Picking the Right Gas MIG Welder for Your Skill Level
The Bestarc 145A is our pick for the best gas MIG welder for beginners in 2026. It gives you real gas MIG and flux core capability, dual voltage for any outlet, and a synergic control that removes most of the setup guesswork. If you want one machine that grows with your skills for the next decade, this is the one to buy.
For a tighter budget, the YESWELDER 160A delivers gas MIG, flux core, Stick, and Lift TIG at a price most beginners can afford. For the absolute lowest entry point, the AZZUNO 130A gets you welding on the cheap, but you will outgrow it as your skills develop. Whichever you choose, budget extra for a shielding gas tank, regulator, and initial gas fill. Then grab some scrap steel from a local fab shop and start practicing. You will be surprised how quickly the welds start looking good.
