FAQs
What size MIG welder do I need?
It depends on the thickest steel you want to weld. Thin sheet metal needs less power, while thicker steel needs more amps and often a 240V power source.
Is 120V enough for MIG welding?
Yes, for light work. A 120V welder is suitable for sheet metal and thin steel. For thicker steel, a 240V welder is generally a better choice.
What wire size should I use?
Thin steel usually works well with .023-inch wire. General steel often uses .030-inch wire, while thicker steel often uses .035-inch wire.
Can I weld aluminum with a MIG welder?
Yes, but aluminum requires more care. It usually works best with 100% argon, and a spool gun can make feeding aluminum wire much easier.
What is better, MIG or flux-cored?
MIG usually produces cleaner welds. Flux-cored welding is useful for outdoor work and thicker steel. The better option depends on the job and working conditions.
Do I need gas for flux-cored welding?
Not always. Self-shielded flux-cored wire does not require external gas. Gas-shielded flux-cored wire does require shielding gas.
