Re: Show off your welds!

Here's one from today. It's so fun to totally just nail one spot on.

Airgas guy told me the green tungstens are not for use with inverter machines like the Diversion 165. Wish they had told me that a year ago when I bought them. Anyhow, I switched over to the purple colored E3 tungstens (I think they're called) and it's a big difference. Real smooth buttery arc.

The only issue I'm having with these tungstens is that the arc wants to dance around a bit when starting, until you really punch it in with the pedal.

I did have a few welds completely blow out (yes, outward), and then the metal just would not accept a weld in that location no matter how clean I ground it out. It was really weird. I think I had a bad batch of metal, with contaminants or water in it. Anyone ever experience that?
