I recently swapped out a bottle of Argon. I have had nothing but dull contaminated welds since I have swapped it. This is all TIG. Stainless Steel 304l fittings that I have been welding for 5 years. THis is a first. No matter what I try the welds are dark in color resembling being way too hot. The tip of the tungsten gets a raised black ring almost at the tip after welding an inch or 2.
I checked the torch for leaks and there are none.
I have tried anywhere from 15 to 30 cf of flow
I changed out the tungsten 3 times and I use a tungsten sharpener.
So, I am stuck thinking its the argon. The gas shop is closed today.....

How does Argon go bad? It is simply a gas. Foreign contaminates in the tank?

Foreign contaminates in the tank? Yes. If someone emptied their bottle and left the valve open and then no one evac'd it then its filled with air. Or they filled it previously with something else and never purged it. |

very possible, we had a customer bring in a machine saying it would weld shitty. MM210 i think with a spool gun welding aluminum. It welded fine in our shop, and when it went back they said it was doing the same thing. We gave them one of our machines to use and they were still having a problem. They switched bottles and the problem was solved. I dont know how it happens but it is definately possible
