Hi can any one help with connecting THERMACUT EXTRAFIRE 75SD PLASMA CUTTER to the arcdroid ? i have connected it via the cnc interface and found the 2 torch wires but it will not turn the torch on

Not familiar with your plasma machine. Are you using a hand torch or machine torch? More than likely you need a machine torch to utilize the CNC port.

It does appear to be a safety switch in the handheld torch. The handheld has a second pair of wires that the mechanized torch does not have.

Definitely haven’t seen that one before but a quick look at the documentation and it seems the cnc port pins you are looking for are 3&4. you should just be able to touch the wires together and have the torch fire.

However like @BobD says you should check with the manufacturer, they may have a lockout that only enables the CNC port when you attach a machine torch (Hypertherm does this) this may require a jumper wire at the torch end to trick the system into thinking there is a machine torch

Hi Andrew you are correct the port pins are 3 &4 and when you touch them together it does not fire up.
However I will check with my supplier and see if I can get a machine torch thanks for the help I will let you know how I get on

Well we’ve sorted the problem out with this machine, it needs a machine torch to operate not a hand torch.

You should be able to work around this with the hand torch if you are comfortable opening up the torch head or the plasma case.
