Start here: troubleshooting checklist
When a problem occurs, go through the troubleshooting checklist first. It is necessary to complete
these steps before doing the recommendations in the rest of this chapter.
As you do this checklist, record any problems or questions. If you cannot find a solution to the
problem by complying with the recommendations in this chapter, or if more aid is necessary, follow
these steps:
1. Get the serial number for your system from the data plate that is on the bottom of the plasma
power supply.
2. Speak to your Hypertherm distributor or authorized repair facility.
3. Speak to the nearest Hypertherm office shown in the front of this manual.
Refer to the Powermax45/65/85/105 SYNC Parts Guide (810490) for

Is the power switch on the front panel of the plasma power supply operating correctly?
Is there any visible damage to the plasma power supply?
Examine the front panel controls
