I ordered a TIG torch for my DC inverter a few days back and have been having a play with it. Had me beat for a bit but soon found out that for less heat to be in the tungsten tip it needs to be run reverse polarity from normal. Then the second mistake was I was using normal oxy filler wire.
I got some proper filler rod today and some 6mm plate for a practice. Did about 3-4 runs just on the plate to get the settings right (100amps) and then did the below. First shot is my first fillet attempt, not real flash in the middle. Contaminated the tip and ended up with a wandering arc. Second shot is my second and final attempt.
I'm going to build the gearbox crossmember tomorrow with the tig so we will see how that goes.
