How to weld sheet metal ?

Sheetmetal can be tricky. Weld at very low amps with a low feed speed. The biggest problem with thin sheet is warping. It warps with very little heat. I usually use a wet rag and weld a spot, douse with water, weld the next spot, etc. Very time consuming, but not as much as trying to reshape a body panel after it has been warped out of shape. You will get blow through if you get too much heat concentrated in one spot, so don't keep the arc on the spot any longer than it takes to get good penetration.

Get some waste at school and give it a go.. They should also have an outreach program. So you can get extra booth time with an instructor in the evenings..
