To set the tone, level of frustration = 11/10
Learning mach,sheetcam and CAD from scratch were easy compared to this THC-300 unit.
Doing test runs with my table, all the thc wants to do is drive the torch down. Voltage readout is 169. Any time I adjust either of the adjustent knobs I can't get it to go up. Turning either CCW I get no reaction, either CW as soon as I pass midpoint I get a fault light. I have adjusted the limits from small to crazy big and it just drives the head down farther.
I am unable to get an arc ok signal using the current transformer. The only way I am able to do this testing is to jumper the orc ok terminals and fool the system.
During initial calibration, the unit must be adjusted to read 100v on the readout. I'm on my second unit now and still can't get any better than 90v
I must be missing something in the mix here, it can't be this difficult.
Anybody with any help would greatly be appreciated.
