I have had trouble welding sheet metal on my project car without it burning through and looking like crap. Im using a miller mig welder with .030 wire, would switching to .024 help to keep me from burning through this stuff?
I have it set to what miller recommends but it still burns through unless i go REAL fast...

When welding on thin metal like a 20 gauge or even 22 gauge sheet metal I use a thin wire. I have the welder set on 1 and the wire speed about 35-40. I also use a 75/25 mix at 30psi on a 120v welder. Hope this helps you out OP

Can you please post up pics of the pieces you welded? I would try the tip being a little further away. Or even have a faster travel speed. are you pushing or pulling?

I forgot to mention if you place the work piece on like a large piece of steal and clamp it down to it. Its another trick to keeping the heat down too.
