CAUTION
Basic troubleshooting of the Pak Master 25 Model Plasma Cutting
System can be performed without special equipment or
knowledge, and without opening the enclosure.
This basic troubleshooting guide covers input power, gas supply,
and torch problems.
For problems not covered here, contact your authorized Thermal
Dynamics distributor.
If a Thermal Dynamics product must be returned for service,
contact your Thermal Dynamics distributor. Materials returned
to Thermal Dynamics without proper authorization will not be
accepted.
The only routine maintenance required for the power supply is a
thorough cleaning and inspection, with the frequency depending
on the usage and the operating environment.
Disconnect primary power to the system before disassembling
the torch, leads, or power supply.
Do not blow air into the power supply during cleaning. Blowing
air into the unit can cause metal particles to interfere with
sensitive electrical components and cause damage to the unit.
To clean the unit, open the enclosure (see Section 4.8) and use a
vacuum cleaner to remove any accumulated dirt and dust. The
unit should also be wiped clean. If necessary, solvents that are
recommended for cleaning electrical apparatus may be used.
When cleaning care must be taken not to move or damage the
electronic components.
