Miller 2050 Plasma cutter issue

I used my Miller 2050 plasma cutter a couple weeks ago, and Saturday I fired it up..and it kept giving me a Cup Problem error light. So I swapped out all the consumables at the torch..and it didnt clear the error.

Any suggestions?

"The ruling class doesn't care about public safety. Having made it very difficult for States and localities to police themselves, having left ordinary citizens with no choice but to protect themselves as best they can, they now try to take our guns away. In fact they blame us and our guns for crime. This is so wrong that it cannot be an honest mistake." Malcolm Wallop former U.S. Sen. (R-WY)

Any six- or eight-legged beasties taken up residence farther down the hose? Now is about the time they wake up and start looking for housing. The fact that it worked a couple of weeks before kind of points to outside influences. Has Miller got a FAQ on that model for error lights and what needs to be checked?

Don't have that one - don't know that model. However I do plasma cutting by hand and by CNC.

Consumables - might be the torch head - often there is a spring loaded push rod of sorts - switch - that is a temperature switch -

Maybe it is locked in the bad position - with some blow back.

Take out all of the screw on parts - look into the head - power off naturally - and see if the push rod detentes and comes back...

That might be the cause.

Otherwise - check out the faq or book.

Miller puts a safety feature in the torch that prevents it from energizing if you put the wrong consumables in it (plasma torches can explode!). Take apart your torch and you will see a little spindle with the wire on it for the electrode. If you push on the other side (what happens when cup is scre wed on) you will see it moves the spindle and it is supposed to push on a l ittle contact. it wears here!. Simply unscrew the lead, rotate the spindle a little so it's off the wear spot, screw the lead back on and your good to go.
