Is there a process to dry machine after Plasma?

[Buggy Chief]

If I expect that moisture has entered machine via plasma cut and affecting my TIG (arc jumps and severe contamination happening), is there a process to try and remedy this? how do you dry out, if at all? I have a filter with a desiccant on the plasma set up, but it is 2 years old and may need to be changed.

At first, I thought my argon was running out, but it isn't, as my tungsten is not turning black, but something is contaminating and I can't hold steady arc.

Any feedback is appreciated.

Just use, or you can disassemble the unit, solenoid and lines and replacing said lines, and cleaning the solenoid out.

Also be sure not to use the water trap when using Argon for TIG. If you accidentally got a slug of water in your TIG torch lines, you can blow them out with plenty of argon, but it takes time to get everything dry. Not as easy in cold weather, either.

So should I just crank the argon up and just press pedal and let flow through? for how long?

It somewhat depends on how much water you got in the hoses, how long they are, the temperature, and a few other variables. But for a 12 foot torch cable I would guess that if you lay it out flat on the floor, so the moisture doesn't have to travel uphill, if you run about 50+ CFH for a minute or two, you should have it pretty well cleared out. How wet was your air? Plasma doesn't like wet air either. I guess this is another thing to keep track of with multi-process machines.

Plasma works fine . TIG was working great. I am starting to suspect bad gas, but wanted to try everything before returning a 1/2 full bottle. Do the filters that have desiccant in them need to be replaced ever so often? Mine is 2 years old.
