Duke, i used to have a big welder, when i started doing this car i bought a little like $300 welder off amazon and i am in love.. the new welders (on a angle grinder) and it made it absolute cake... BTW.. flux you can't get low enough for sheet metal and it makes a mess.. (i assume you are doing bodywork? I cam in late and didn't read back)
This is the welder i got. they prolly have a updated version.. did a bunch of research before buying it and have been super happy.. got rid of my old big *** welder..
