Mig welding problems

How come sometimes (on car body panels) I make a weld that is OK... then othertimes I create a bigger hole than I started with? The weld process goes quiet when it happens if that is any help.

I think you need to try holding wire away from your work. The closer your wire and tip are to the work the more heat. Try to find a happy meddium. Hold back a little at a time, and if you burn a hole back off for a couple of second let it cool. Next try staying back about 1" and let the wire build up a pile thats almost covers the hole. Wait a few seconds let it cool and than weld over the area. Paint is hard to weld so is worst than others, cleaner the better.

Seam welding does wrap the metal and there can be a lot of heat, Andy is right about trying to stitch weld thin metal.

Play on some tin cans if you can . Practice on old junk and in no time you have it down.

Good Luck!!
