How to weld sheet metal with a arc welder.

This adds two operations. It is recommended that a welder should use 023 or 024 inch wire for light gauge sheet metal work. To weld sheet metal with solid wires use electrode positive ep or reverse polarity. The real trick to weld sheet metal is to use a wire feed.

That makes this a one handed process. Arc welding is a versatile method that uses alternating currents to create a high heat arc that melts your flux.
