One technique not mentioned that allows one to weld thinner metal than the welder is designed for is to pulse the mig gun. Think about rapid firing a semi auto pistol. I used to weld up 0.025" bandsaw blades with my buddies mig, theoretically it's impossible to do that, but by pulsing the weld and grinding off the blobs it worked like a charm.


I did mention this and its called trigger welding
