CAUTION
Basic troubleshooting of the Econo-pak 50 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 in this Section, contact your authorized
distributor.
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 sensi-
tive electrical components and cause damage to the unit.
To clean the unit, open the enclosure 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.
