I have a new PowerTIG 185, with the new flexible 17 torch, running 110 volts. I have gotten rather good at laying a bead on flat steel, though my success with filler rod is only adequate so far. 100% argon @ 7 LPM, #4 cup, red 3/32" tungsten, Weldcote ER70S2 3/32" filler, 1/4" protrusion sharp tip, steel cleaned with chemicals then brushed immediately beforehand, 80 amps, 1/8" plate. So I thought I would try a gas lens setup. $30, and I'm trying a #6 cup. But an arc doesn't start quickly, and when it does it immediately gets dramatically larger and brighter than it should (than I'm used to), even when lifted well off the plate. Too bright to see the puddle, and I have darkened my faceplate. Bad setup? Advice would be much appreciated.
