I looked for a leak too. Nothing there.

I got mine from Tec Welding in Auburn.

Ill have to take this one back too and ask them to give me a bottle from another batch.

 

exactly. i got a bottle i know 100% was C25 one time after i bought ar.

98ctr if you're sure on the gas check polarity if DC / AC balance / leads, use a 100% new stainless brush, wipe with acetone immediately before welding.

turbod you'll find alot of places either restrict the flow to a trickle, or had it at a trickle; learned better & cranked it up. yet by canking it up the gas leaves very turbulant. Swirling air back into the mix. i got a $100 bonus on a pay check several months back by "solving" all the continual coverage problems at that particular shop lol!

 

I changed out the gas lens. Its definately the bottle.

 

Here what happend. I was making an CAI for a customer and my gas was low, so I thought I would replace the bottle so I don't run out over the weekend.

Same set up on the tig, new bottle and everything went to shiet.

Changed/cleaned/etc everything I could and still the same *** black crap in my aluminum puddle.

 

if you get your gas from auburn go to haun welding supply in auburn ...i work for the main fill plant in syracuse and i know our ---- is 100%...

 

Happens. We swap 12 bottles every two weeks we typically see 1 or 2 that weld noticeably different then the rest.

I've been looking into a manifold/purifier system to reduce these effects and I also looked into a liquid argon system but the evaporation rate from the liquid tanks exceed the usage for us.

No luck yet.

 

You talking Indiana?

 

no new york i dont know if hes talking about new york or whereever

 

maybe argon is coming from china now too....

 

Ah ok, well theres syracuse, and aubrun that are pretty close to each other in Indiana. Crazy ----.
