Hi,

Today after finishing a job my plasma torch stopped working..it's not going up or down.
I have hypertherm power max 65,
HYD-THC xpthc-4h height controller and starfire control system.

Both up_limit n dn_limit led in HYD-THC are on..I think if those led goes off then my problem might be solved..wat may be the reason for them to turn on..
Pls help..
