What is MIG Welding?

You might hear the term MIG often, but what does it actually stand for? 

MIG means Metal Inert Gas. It’s a welding technique also commonly known as GMAW or Gas Metal Arc Welding.

How does MIG welding work?

MIG welding uses a consumable material (usually a wire electrode) continuously supplied into a weld pool to join base materials. 

At the same time, a gas blend shielding gas is applied to the weld pool to avoid oxygenation.

This means that in MIG welding, the electrode also acts as the filler material. 

This makes MIG welding more prone to weld spatter, no matter how much caution is taken. Aside from being a safety hazard, it’s likely that you’ll need to polish and sand your car panels after MIG welding.

What are the Applications of MIG Welding?

MIG welding is best applied to projects involving thick and heavy-duty sheet metal.

MIG welds are most common in large construction and manufacturing projects.

They are also widely used in home improvement and automotive repairs because it is relatively inexpensive and easy to learn and control.

Why is MIG Welding Better for Automotives and Car Panels?

The most common welders used for auto repairs and respiration is MIG, TIG, and Arc or Stick welding.

Find out why MIG welding is best for your car panel.

MIG Welding vs. TIG Welding vs. Stick Welding for Automotive Repairs

TIG Welding

The main advantage of TIG welding is that it produces the cleanest and most structurally sound weld.

However, you will find that TIG welding is extremely difficult to learn, expensive, and slow.

If you’re dealing with car parts and repairs, TIG welding can be an impractical choice.  

TIG welding is most appropriate for aluminum and very small and thin metal sheets.

Stick Welding

Arc welding is the most inexpensive out of the three. 

However, it produces the most amount of spatter, and it’s time-consuming and challenging to learn.

It also doesn’t work well with precision and very thin metals under ¼ inch.

Why is MIG Welding the best for Car Panels?

MIG welding is arguably the most beginner-friendly welding method. 

It’s less time-consuming and easier to learn than other welding methods.

MIG welders can handle most common metals in cars, including stainless steel and aluminum. It is also great for handling thick metal, as well as thinner metals up to ¼ inches.

Considering all of these factors, MIG welding is the most practical, versatile, inexpensive, and fast method.

What to consider before buying an MIG Welder for Car Panels?

Duty Cycle

The longer the duty cycle, the longer the time you can run your welder without stopping or overheating.

For hobbyists and DIY welders, you will most likely need only short-term welding for approximately one-inch beads. In that case, duty cycles of less than 40% will be enough for your needs.

Input Voltage

120V machines deliver a high current, but they are more appropriate for short cycles. If you are a professional automotive welder, then you should invest in a 220V MIG welder for a longer duty cycle.

Amperage

Thinner metals at 18 gauge to 3/16 need current densities from 100 to 130 amps.

If you are welding steel up to ¼ inch, you’ll need to get a MIG welder with at least 180 amps.

Maximum and Minimum Metal Thickness

Thickness of car parts usually falls into a narrow range, but make sure to find a MIG welder that can handle your sheet metal.

What are the Top 3 Welders for Car Panels? 

Whether you’re a beginner or a professional, these car panels offer the best quality and functionality for car panels:

Best for Beginners: Lincoln Electric K2278-1 Handy Core

Specs

• 0.035 flux core wire
• 20 amp outlet
• Duty cycle of 20% at 70 amps
• Can weld mild steel, aluminum, stainless steel

The Lincoln Handy core s best for repair work with mild steel, so it’s a great choice for car panel work.

The Handy Core is a great choice for the light-duty welder with its voltage and duty cycle of 20% at 70 amps.

It can also handle a wide selection of materials, including steel, aluminum, and precision welding with thin gauge materials, thanks to its inverter technology.

The Lincoln Handy Core can weld mild steel 24 gauge up to ⅜ inch, aluminum at 18 gauge up to 3/8 inch, and stainless steel 20 gauge up to ¼ inch.

Another great thing about the Handy Core is its different control panels, including wire speed control and voltage output.

Pros	Cons
Versatile control panels for wire feed speed (0 to 300 in/ minute) and voltage output Great for home garages and workshops Simple set-up Runs on home electricity	Complicated to handle thicker welds Not suitable for heavy-duty welding Does not use gas

Best Lightweight and Space-saving MIG Welder: Forney Easy Weld 140 FC-i Welder

Specs

• 0.30 flux core wire
• Infinite voltage and wire feed speed control
• Up to 130 amp output
• 30% Duty Cycle at 90 amp

The Forney Weld 140 FC-i welder prioritizes comfort and functionality for both the veteran and hobbyist welder dealing with steel, cast iron, copper, and steel alloy.

It’s an exceptional flux-core welder that can handle a weld capacity of up to ¼ inches. It can also handle 2 to 10 pounds of wire spools.

You’ll be surprised that this lightweight MIG welder has a metal housing for more convection and a longer duty cycle.

Our favorite features are the infinite wire feed speed control that is a rare sight in portable welders such as these. 

Pros	Cons
Lightweight at 19 pounds Compact and space-saving Durable metal housing Wire feed speed control Runs on home power	More expensive than most welders but worth it Only compatible with Forney parts Flux core is more tricky to learn

MIG Welding for Car Panels (FAQ)

📌 Can I weld car panels with glasless MIG?

Yes, you can use gasless (or flux core) MIG welding with car panels, but it will require more expertise.

Going for gasless MIG welding also produces unclean welds and a lot of spatter. We recommend you go with the Miller Electric if you’d like good functionalities for both MIG welding and flux core welding.

📌 What is the best MIG wire size for car panels?

For automotive sheet metal, the thinner your core wire, the better.

A core wire of 0.23 shielding gas (argon mixture) is ideal, but you can use wire cores of up to .030 with more caution to avoid burning.
