Ive just bought a clarke 160 and auto mask from weldequip (Many thanks for all the help). I have took my gf car for the test today and it failed on corrosion on the outer sill. I have cut all the old rust out and cut a patch out of 1.2mm steel sheet. I have made the patch slightly larger than the hole so I can do an overlap weld. Has anyone got ay base settings for me to start with as im pretty new to all this. I am obviosly going to practice a bit before trying to weld it up. Many thanks
