Temporary plasma cutter from TIG?

[eide]

Is it possible to do any short-term plasma cutting with a TIG setup?

i.e. could I theoretically get a plasma torch, some air, and use my TIG machine to do some plasma cutting?

What are the actual machine requirements for the processes? Amp, voltage, etc.

I have not done this myself but read that you can cut thin metal with a tig torch. You would not use compressed air like a plasma and the cuts are not as clean. I am not sure if the everlast machine will allow you to run a tig only machine for plasma but I don't think it will. Other machines will not work like this. I would love to see more information if it is possible with the Everlast units.

I do not think that is possible or advisable. Although it is possible to MELT THROUGH thin metal with any welding process this is not the proper use of a machine and bespeaks a gross lack of respect for the equipment. Mark and Mike could answer your question about how the machine works but probably faster to just wiki "plasma cutter". I know the process of ionization has to do with the movement of the air and the particular kind of metal used in the electrode... halfnium i think it is called....

No,
Don't try it.
Even though tig and plasma share roots together, it won't do it

why couldnt you move the tungsten back inside the cup, the the amp up to 200 or so and bump the argon out to 50 - 60 or so? I think it was just on Jodys site that I saw a video of him setting it up that way

This talks about doing the tig cutting in thin sheet from Jody's site.
