Warren, Thank you too. I'm a leaner. I'll have to work on my posture to put less force on my torch hand.

I think I figured out what a contaminated weld puddle looks like. This would be tungsten contamination.

Learn something every time you weld!

I think it's tremendous that you're plowing away, working towards a goal, unafraid of public commentary. With that determination, IG will no doubt have a new, highly trafficked account 8-)

Today's contaminated pool is a 309LW failure.

Leaving the wire stuck in the puddle isn't contamination. It's something I do regularly. I use it as a location to taper of my arc as I reposition. Then I just light back up on the wire.
I have more questions than answers

And doing that also protects the filler wire from contamination from being exposed to the atmosphere. It's commonly intentional for stainless pipewelders to do this. Now, if it were your tungsten, that would be a different story... :o

That was the "W" in the failure mode. At one time I had 2 tungstens and a filler at the same time.

Wow, what a break from the internet. I didn't mean to just disappear. I've been welding regularly just not getting online much. That broken chair that I was welding seems to have lost it's temper and now if you lean back too far it changes the neutral point where the rocking chair rocks. Oh well, it was broken before I tried to fix it.
