Could someone please offer me some tips on how I can do uphill beads using MIG. I've taken this photo of one attempt on 6mm mild steel for a tee joint. Volts were around 16.7 and amps were around 120-140'ish. I tried the "triangle" pattern manipulation as shown on Welding Tips and Tricks, but just couldn't get it right. I aimed for a 90 degree gun angle, but probably got closer to 80 degrees. Any help would be appreciated.
