TROUBLESHOOTING

The troubleshooting procedures include the

Initial Resistance Checks and the Corrective

Maintenance Checks. These procedures are presented in a flow diagram format.

The complexity of the circuits require that service technicians have a working knowledge of inverter
power supply theory. In addition to being technically qualified, technicians must perform all testing
with safety in mind.

If questions or problems arise during servicing, call the Hypertherm Technical Services Department at
1 800 643 9878.

Troubleshooting Procedures

Maintenance of the Powermax800 power supply consists of performing visual inspection and trouble-
shooting procedures.

•

Refer to the system wiring diagram when performing the checkout procedures.

•

To locate power supply and torch components refer to Section 4 for 208/240/480V and
200/230/400V power supplies, and Section 5 for 400V CE power supplies.

•

After the problem has been located and repaired, refer to the

Sequence of Operation flow

diagram in this section to test the power unit for proper operation.

Visual Inspection - External

1.

Inspect the outside of the power supply for damage to the cover and external components.

2.

Inspect the torch and the torch lead for damage.
