If all you are doing is thin gauge sheet metal, then I would go with 023,.024 or .025 solid wire with c-25 gas. The wire sizes are basically the same. I mentioned all 3 because I don't know what you have available locally. Make sure you get the right contact tips when you get the wire. The tip size should match the wire size , except with those three sizes. They all seem to be the same. As for he settings, there should be a chart on the door. The settings should get you started. You would probably need to adjust the wire speed a little to find the sweet spot.

If you need to do some heavier steel than sheet, then .030 solid wire would be my next choice.

If someone could be more specific on what gas and wire to use That would be great, I know nothing about welding. I just borrowed a freinds Miller 172 and need to know what wire to use and what settings are best for welding automotive replacement floorpans and body panels. Also if you know any good tricks to a good weld let me know.
