You need something like the blue block on this image - this is the relay you need to find.



They can be black, blue, any colour but will look similar.

Have you got a break-out board even??? This will be located at the machine end somewhere.


Please do not just fit any old relay, you could blow your PC very easily.

Ah, this one...

that board does not have a torch relay fitted, you will need an add-on board i think.

Personally I would get a more plasma oriented board, opto-isolated and fitted with one or two relays.

If you are building a Plasma CNC you will almost definitely need a THC as well, might be worth your time looking at CandCNC.com I think

This is what you are looking for.  I would steer away from the CandCNC products as they are far to complicated for the average DIY plasma cutter

Only advice i can give is to go steady!

Get the machine up and running, making moves, then add the Plasma and debug that, then add the THC.

Do you have a plasma unit yet?

Is the machine built or is this a rebuild/mmodification/change of purpose thing???

I do have the machine running. I also can cut if I turn on the plasma by hand,I mean turn on and off manually.

Brilliant, thats 95% of the battle won then :)

Sounds like the relay will do it.

AFIK PWM is for motor speed control on stuff like Routers, mills, lathes etc

wow Dave, I am very happy to know that. I suppose I will wait for my relay and try it out. Thanks for all your help!
