I am patching a few bits of metal around the bottom of the door sill, an am having trouble welding the new patches in because the metal is so thin. I matched a piece that I cut out for thickness, which turned out to be 22 guage from the local hardware store. It is the actual existing body work, though that I am burning through. I am using a Lincoln Pro 100, on the lowest setting. It recommends that I use solid wire and gas (MIG) for metal this thin, but I don't currently have it set up for that, and I use flux core. Will solid wire and gas help that much? I know it makes for easier welding in general. Any other tips, all the metal in this area is really thin.
