having a problem with a mechinized tig welder. The welder run a 5ft long weld on 321 .016 stainless. It has an AVC (automatic voltage control)so it keeps a set voltage while welding. The problem here lately is the it keeps sticking the tungsten after welding a short distance.
Could it possibly be that the tungsten was being ground to a sharp point? Resulting in the point falling off after welding a short distance, the AVC reacting to the voltage change and dipping(sticking)in the part?
It may just be a motor worn out or something else. Simple things first. I didn't see the tungsten before hand. could that be a cause?
