A friend is making a large sculpture out of corten. Theres about 1000 feet of joint to weld. Hes using mig with the right wire but would like to use his tig unit. Using 3/32 electrodes,15-17 cfh gas the points round off in about 5 inches of weld. He's using pure argon and ceriated electrodes. Does this sound about normal for wear and proper gas? Syncrowave 250 electrode negative, no pulse. Max ampreage 140 and probably at half throttle.
