can you turn your wirefeed welder into a plasma cutter.

can you turn your wirefeed welder into a plasma cutter.  if you replace your gas line with an air line  and connect the cables to the  ,- terminals?

You might be able to.  You'll need the air control and the feed hose and cables.  Buy the cutting head that fits the cables.

You might have to adapt your connections also.

Be careful with the duty cycle.

Let me know how it comes out, I've got one that I would love to do the same thing to.

 Unlikely without substantial electrical modifications. Plasma cutters usually use high-voltage, high-frequency to start ionizing the gas. Most wire-feed welders are DC only, except for the quite expensive models, and I don't think the frequency is high enough even in the AC models.  There may be some way of making it work, but for the time, cost, and possible danger, it's probably best to just buy a plasma cutter.
