Well,the gas suppliers said the cylinder was contaminated and refilled at no cost.Welds now are perfect.I still cant figure out how this happened with three different cylinders and suppliers,I guess just bad luck.
Thanks for your help.

Are your filler rods clean and corrosion free?

O ring in good shape on the cap?

Yep,filler is clean and the torch is brand new.

Dane, Could you post a picture of one of your welds? Also, where are you located? Maybe someone on the forum is close by and could take a look. Jimmy, I live in Patagonia Argentina.I think it might be a bit far for you guys.Attached (i think )is a picture of what Im talking about. Let me know what ...

Im not absolutely saying its not me,its just that one day everything was fine and the next it wasnt.I guess you can say that about a lot of things in life. I don't think it is you. I'm just saying we used to be able to narrow it down easier. The most common issues were with the guy welding and it w...

IF it's in the machine, it's in the gas line. It's hard to convince folks of this, but a leak in the like won't "blow argon out", it'll "suck air in". It's a function of static vs. dynamic pressure, put in equations by Bournoulle (sp?). If your gas analysis comes back "good...

Only time I have not had argon issues is when we used liquid argon on a manifold system but you have to have 4-5 welders using it or it freezes up. When Bitech was still in business, my regular cylinders were fine too. Once Bitech got bought out, that marked the start of gas issues and it seemed a ...

Dane, Is this happening with aluminum from different sources? (i.e. different sheet or angle or tubing, whatever) My thought was mabe something in the alloy. As others have said you can and will get argon that's not up to industry standards. This happens mostly because when a cylinder of argon is f...

Thanks everyone, I have changed tungstens,collets etc...,so Im down to gas or the machine.My supllier has the tank now for analyzing so I will know soon if its contaminated or not.Do you guys think maybe the machine could be at fault?My first theory was that the cleaning cycle wasnt working but afte...

Hello everyone, All of a sudden I started getting black pepper flakes in my aluminum tig welds.Turned the positive half cycle to max and didnt change much,my tungsten balled up a lot when I did this though so I figure the half cycle attributed to cleaning is there(cant blame that,I hope.Dont want a ...
