I own and operate 4 Proma THC, one is on an production machine doing 12 h 6 days a week with no problems ever.
Just as a generall rule,
be sure you have the polarity right
be very carefull with plasma, it IS exponentialy more dangerous than a MIG or TIG welder
use quality cables with good isolation and as close to plasma as posible
if you have an inverter plsma, voltmeter is not much use due to high frequency
etc etc
More info on your setup would help and pictures too.
