And that's why we are here with tech support to help in that, but there are threads that deal with this as well so you wouldn't have had to go it alone.

As far as the arc, is it like a small spark plug arc, sort of like little lightening bolts? This is the HF. Loosen them up to .035" to . 040". AND are you using your foot pedal? What is your start amps, upslope,downslope, and end amps set at? Are you in 2T or 4T? What are your panel amps?
Got the opportunity to do a little more detective work on my PP256. Here's how it went:
Removed the rear plastic end and tin cover (so much easier this way, thank you very much)
Inspected for loose connections, broken this, or burnt that... Nothing remarkable
Readjust points to .035
Torch + Ground clamp -
Panel setting @ 50 amps
Air pressure set to 40 psi -Water separator /filter at the compressor, water separator and dessicant filter at the rear of the machine
Function switch in CUT
AC/DC switch in AC
Machine switched on, pulled torch trigger, watched points. Bright momentary arc - Release the torch switch, arc again.
Placed torch on the edge of a clean, grounded piece of plate, stand-off in place, pull the trigger, NOTHING!
Remove the stand-off, torch in direct contact with the grounded plate and got an arc. Very disorganized with no cutting action. High heat was developed and there was an indication of slight damage to the torch tip and nozzle.
Discontinued any further testing as to not ruin my brand new plasma torch.

I'm going to try and set up the TIG torch and be better about settings and observations. I'll get back to ya'.
