Hi All

Pre Interface plasma torches ...

Does anyone use the RAV-01 card in thier torch to get an 'Arc OK' for MACH3 (along with a Digital Current Probe & THC Sensor PWM)?

I put the card through the tests; Torch fire & Raw Arc Volts. It FIRES the torch when both "FIRE" buttons are pushed ... when I push all three (2 torch fire 1 Raw arc volts), the torch fires (as it should) and the Raw Arc Volts LED FLASHES on and then off real quick. My question is; Is the LED supposed to STAY lit when the buttons are held?

Polarity for Raw Arcs is correct (+ work clamp & - Torch electrode). The test instructions states it's supposed to put out between 130 to 180 Volts DC.
According to my meter, my torch is putting out 98 to 100 volts.

Could this be the cause for NOT getting an 'Arc OK' signal to the THC Sensor PWM? NOT getting at LEAST 130 Volts DV?

ALL other tests check out okay for signals (following instruction manual). The whole setup works and cuts ... With the Torch Height Control turned OFF.

Anybody have any suggestions?

Thanks ....
