Hi, I bought an R-Tech MIG 4 weeks ago & now that I have a space to work, + a bench, and a 16A socket, I thought i'd start with the MMA welding. Watched the tutorials on this forum, which were great. Then practiced for a few hours using 3mm to 10mm steel, using 2.5, 3.2 & 4 rods, all 6013 Siffrode. Made many notes of what amps worked best. Below is a 50mm x 4mm box using 2.5 rods. Just one decent run managed, pretty obvious which one ? Intend doing LOTS more practice ! So, my question is, I am making a vice stand and need to weld 100mm dia x 4mm pipe to 10mm thick steel base plates. I think I should use 3.2 rods at around 130A, but when I tried some practice runs, I'm pretty sure I was close to burning through the 4mm pipe. Advise / Recommendations please ?
