It is recommended that a welder should use 023 or 024 inch wire for light gauge sheet metal work.

However if you are dealing with materials that are 18 gauge or thicker one should be able to use 030 inch welding wire. The real trick to weld sheet metal is to use a wire feed. I only have a 110 v arc welding machine and i want to weld car panels but i keep blowing out the metal.

An arc welder can be a useful tool to have around the house as it can weld almost anything as long as you take care of the material and thickness of the metal sheet being welded.

Although this could be the main reason others include flux problems using low ocv welders or the incorrect welding technique. The rationale of the last point is to make it harder or more realistic for auto body welding.
