General degradation of weld perfor-
mance
Improper fan operation
1. Improper fan operation.
2. Open thermostat circuit.
1. Control PC Board Battery.
1. Wire feed problem.
2. Cabling problems.
3. Loss of, or improper Shielding
Gas.
4. Verify weld mode is correct for
process.
5. Machine calibration.
6. Wire feed problem.
1. Check for proper fan operation.
Fan should run in a low speed
setting when the machine is idle
and in a high speed when the
output is triggered. Check for
material blocking intake or
exhaust louvers, or for excessive
dirt clogging cooling channels in
machine.
2. Check for broken wires, open
connections or faulty thermostats
in the thermostat circuit.
1. Replace the battery (Type:
BS2032)
1. Check for feeding problems. Make
sure proper gear ratio has been
selected.
2. Check for bad connections,
excessive loops in cable, etc.
)*/ The presence of heat in the
external welding circuit indicates
poor connections or undersized
cables.
3. Verify gas flow and type are cor-
rect.
4.Select the correct weld mode for
the application.
5. The power source may require
calibration. (current, voltage,
WFS).
6. Check for feeding problems. Make
sure proper gear ratio has been
selected.
