Wiring MASSO G3 with THC1 and PTS-1


Under Multi-head enable plasma torch box and leave the MASSO DTHC software module required box unticked or it will not work.

You can leave X, Y & Z offset at 0 if you are a standalone Plasma machine.

Torch Touch Offset value is used to compensate for the difference in torch height with respect to the touch-off switch. This value is not used for Ohmic touch.

Wire the THC to MASSO as shown above

Remember to invert inputs as needed to show Low when they are not active. eg Plasma-Arc OK, THC-Up & THC-Down

Inputs are inverted by selecting the input and pressing the spacebar.

Enable Plasma and leave DTHC software module disabled
