0-98-2 fault: torch or plasma power supply
If you see an 0-98-2 fault, do the following to identify if the cause of the fault is with the torch or with
the plasma power supply.
Do a test of the plasma power supply
1. Set the power switch on the plasma power supply to OFF ( O ).
2. Disconnect the SmartSYNC torch from the plasma power supply.
3. Set the power switch on the plasma power supply to ON ( I ).

A 0-50-0 fault code shows if the torch is disconnected when you set the
plasma power supply to ON (
I ).
4. In the quick-disconnect receptacle on the front of the plasma power supply, measure the
voltage between pin 5 (blue wire) and pin 7 (orange wire). Refer to
Figure 37 . Is the voltage
approximately 18 VDC?

If yes, the problem is possibly with the torch. Continue with Do a test of the torch on
page 128.

If no, continue with the next step.
5. At the J20 connector (for Powermax65/85 SYNC) or the J17 connector (for
Powermax105 SYNC) on the power PCB, measure the voltage between pin 1 (blue wire) and
pin 2 (orange wire). Refer to
Figure 37 . Is the voltage approximately 18 VDC?

If yes, replace the quick-disconnect receptacle.

If no, replace the power PCB.

If communication faults continue, replace the DSP PCB.
