Well I hate to be the bearer of bad news, but I bought the cheapest welder that HF has to offer! lol. I have seen others use this on a datsun and weld in panels without too much issue. I know it burns hot, I know it uses flux but I plan to do small beads and move around to get it done right. I am practicing with sheet metal now.
If you think this is a very bad idea let me know, but after doing testing I think it can be done. Might not be the cleanest, but It can be done.
My dad always tells me "SBE" Shitty but Effective. That's my goal.
