Got everything wired up in my Hypertherm 1250 according to the diagram in the Candcnc manual for the 1250 model. I am still learning to use the mach interface but I am not able to fire the torch manually from the software. The DTHC online is lit green on the screen but pressing the manual fire doesnt work. What am I missing? I do hear a click coming from inside the 1250 case but get nothing else.
Your torch switch should be hooked up the the DTHC card. Can you get the unit to fire by hand? Sometimes its the plasma consumbles (torch ignitor) that fails due to consumable life and water in the line. Check for
2. Wiring on the DTHC card
Verify with the digital manual that all leads are in the right spot
Your DB9 cable is plugged in
1. On the plasma unit
You can fire the unit by hand and it does indeed make contact in the head and fire the plasma torch.
Chances are you dont have the switch wired to the card correctly.
Yes it does fire by hand. I double checked the card when I hooked it up but I will look again. The DB9 cable is hooked up because I can hear a click inside the hypertherm case when i press the torch fire button on the screen. I am going to mess with it today and see if I can get it working
No air flows when I hear the click but the air is hooked up with pressure and when I pull the trigger on the torch manually the air comes out as well as the arc.
I think it has something to do with the hand torch being used and the actual Hypertherm circuitry. Right now the torch switch is wired to the board inside the plasma. I just looked at the Hypertherm manual and it said it is disabled when using the hand torch. Do I need to splice into the switch wires coming out of the hand torch and not use the connections on the board? Im thinking that is probably it.
I think you should call Hypertherm tech 1-800-643-9878 I do believe this could be an issue if the DTHC is hooked up you should not be able to fire the torch usingthe handle.
I fixed it by splicing into the trigger wires for the hand torch right after it enters the case. The safety built into it does not allow the trigger to be turned on from the board with the hand torch installed. I originally installed my trigger wires onto the plasma board which is why it was not firing.
Now if I could just figure out why the arc ok signal is not working/sticking I will be in good shape and finally cut some steel.
