If the Client ID and the Operator ID in the XPR web interface are the
same on your device, you are in control of the plasma power supply.
1. Remove the power from the cutting system:
a. Set the line-disconnect switch to the OFF position.
b. Make sure that the power-indicator LED on the plasma power supply is not illuminated.
2. Supply power to the cutting system:
a. Set the line-disconnect switch to the ON position.

3. To select the device that has control of the plasma power supply, send a process.
Use ohmic contact sense
You can use internal or external ohmic contact sense. No action is necessary for internal ohmic contact
sense. To use external ohmic contact sense, make the following modification to the ohmic wiring inside of
the TorchConnect console.
When you work with ohmic contact sense, it helps to know the following conditions related to ohmic
relays:
■
The ohmic relay is usually open when not powered.
■
The ohmic relay is closed and ohmic contact is enabled, except during ignition or when:
□
Cutting with a water process, or
□
The remote on-off switch is in the OFF position.
■
With external ohmic contact sense, the relay is still used to help isolate the ohmic circuit from high
voltage.
1. Remove the power from the cutting system:
a. Set the line-disconnect switch to the OFF position.
b. Make sure that the power-indicator LED on the TorchConnect console is not illuminated.
2. Disconnect the ohmic wire from J3 on the ohmic PCB in the TorchConnect console.
3. Connect the ohmic wire that you removed from J3 to J4 pin 1.
4. Do you have a third-party ohmic circuit?
If yes... Remove the plug from the sheet metal on the TorchConnect console to get access to the
ohmic wire inside. The plug is below the torch lead connection, as shown.
