So the issue seems to be corrected. I switched back to pure tungsten and balled the tip. Raised the balance to 75% and lowered the amperage to around 170. Picture below. Not a pretty weld but controlled and no contamination.

Im using a Miller Dynasty 300 DX. Set on AC, Balance between 65-70, and frequency at 120Hz. I don't think I understand Balance as well as I thought. What is the reference point for the percentages? If I'm at 70% then is that 70% EP and 30% EN or the other way around? Is a higher percentage greater o...

I appreciate all the feedback and answers from everyone. Very helpful. So I have gone back to a ceramic cup, now using a Thoriated red tungsten, am operating between 200-230 amps and and floating between a balance of 65-70. And I'm still getting splatter. I have cleaned the material religiously. I'm...

I've done that. Are you sure that you're getting gas (ARGON) through the torch? Are you welding on AC? And is the balance set correctly? As best I can tell, yes. I'm showing 20psi on the tank outlet and I hear the gas discharge through the torch before and after. I'm welding AC. I'm not sure what b...

That's a pyrex gas saver kit from CK. I'm running 20psi to the torch. Yeah, I should try switching back to the ceramic to test

Having issues with aluminum splatter. I'm welding 1/4" aluminum. using a 1/8" pure tungsten at 200-220 amps and 1/8" filler rod. I've adjusted the amperage settings and used clean electrode but I'm still getting a mess and the electrode is melting. Ive included pictures bellow: weld.j...

Hey. First time poster. Hope this is the correct area for this sort of question. So I am new at tig welding. I am welding an interior corner joint of two pieces of 3/8" aluminum. I'm using a 1/8" pure tungsten electrode set at 200-220 and using 1/8" aluminum filler rod. The issue I'm ...
