Tips for welding; 1.Vertical-down = high amps/voltage; rod angled down 5 degrees below horizontal, or more; fast speed. Good for welding sheet metal, or making a cosmetic past over a vertical-up weld. Does not penetrate very deeply! 2. Vertical-up = low voltage/amps so that it will just hold an...

Seems as if the steel is the major problem! There is no need to weave for most GMAW welding, the bead shape will be determined by the speed, voltage and wire-speed. Start with a high voltage and if it starts blowing holes, or under-cutting, reduce the voltage and wire-speed by small increments...

HAFCO have a cheapish one but I can't speak for the quality having never used one. I thought of making one as well, but making the rollers etc. would be rather time-consuming. The most important thing is to make the frame so that it doesn't flex - I was thinking of an I-section made from 8mm...
