Trying to teach myself to TIG welding with my Dynasty 200. I was all set up last night to practice on some 1/8 aluminum coupons using 3/32 Ce tungsten. When I started the arc this white frost covered everything. Hadn't seen that before. Figured I had screwed up the tungsten prep. Switched to 3/32 lanthana>>>same thing. Then I figured out that I hadn't turned on the argon at the tank. Duh!!!
Anyway, this frost (al oxide???) is in the cup, on the tungsten and on the gas diffuser. Can I just resharpen the tungsten and blow out the cup/gas diffuser or do I have to throw them away and start over???
