I have to weld in a new front trunk pan replacing the hole left from an AC unit. I have taken two MIG classes. Beside being a newbie, I have other limitations to consider.
I don’t have access to a 220 line. I’m inexperienced. It would cost me $1000 to have it professionally done. And I don’t want to buy a bunch of equipment for one job. Can I use a flux welder? There a couple cheap units at Harbor Freight (under $150) on sale right now. What don’t I know that I should know? Thanks (IMG:style_emoticons/default/welder.gif) |

True MIG (shielding gas) is the only way to go for any body work. Without the shielding gas you have slag on every weld, and invariably you will get weld inclusions (bad spots) as a result. With shielding gas you can weld on a prior bead without knocking the slag off. You can also use a .023 wire which is better for thin metal. I’ve never used a flux wire welder, so I’m not sure what size wire.
