I have a 50 P that is under warranty, but if there was something I could do to get it back up that would be better than the shipping, repair/replace, return shipping.

I have two driers inline (one at compressor, another that came with it on the back of the cutter. I was using the cutter and everything was fine, and a few minutes later went to use it and there was no spark Pilot arc or anything. The readout still suggests a setting of 0-50A, the switch engages on torch and air solenoid opens, but no spark. Unit was replaced for a similar failure a few months back. I can't figure out if I'm doing something to cause this or if the 50P is a high-failure item in this manner?

I have verified continuity on torch and no shorts. I verified intake power to be correct 220V. Any help would be appreciated.
