Operator Manual
Note: When the power supply operates at the
Lower Limit, the line voltage LED will illuminate
and the power supply will function with some
performance degradation. At -20% of the System
Line Voltage, the line voltage LED will illuminate
but the torch will not function. To avoid
performance deterioration, the input voltage
should be /-10% of the System Line
Voltage.

4.1 The retaining cap is loose.
Tighten the retaining cap.
4.2 The torch is defective.
See
Technical Questions on page 5-7.
5.1 Power supply voltage links are incorrect.
See voltage configuration settings in
Section 3.
5.2 Line voltage is too high.
See the table above.
6.1 The power supply has exceeded the
capacity of the fuse.
Check the fuse for proper amperage rating.
See
Power Requirements in Section 3.
Check power cable for a short circuit or loose
connection.
7.1 One of the internal thermostat switches
has opened due to overheating.
Leave power supply on to allow the fan to
cool the power supply down, then shut the
power supply down and restart. Clean the
internal air filter (if installed). See
Removal,
Cleaning and Replacement of the Cooling Air
Filter earlier in this section.
4. The power supply shuts off immediately
after it is switched on.
5. The power supply shuts off approximately
5 seconds after it is switched on.
6. The fuse on the incoming power line fails
during cutting.
7. The POWER ON LED is illuminated, the
