There is no properly established electric contact between the welding
unit and the fitting (check cable connectors pushed on fitting), or the
heater coil is defective.

The input voltage is below 175 volts. Adjust generator output voltage.

9.1.4 Overvoltage

The input voltage is over 290 volts. Decrease generator output voltage.

9.1.5 Overheated

The transformer temperature is too hot. Let the welding unit cool down
for about 1 hour.

9.1.6 System Error

CAUTION!
The unit has to be disconnected immediately from the power supply and
the fitting. The auto-test has found a system error. The unit must no longer
be used and has to be sent to an authorized shop for check and repair.

Errors During Welding

All errors that occur while welding is in progress are also indicated by
an audible alarm.
9.2.1 Low Voltage
The input voltage is below 175 volts. The welding unit triggers the au-
dible alarm. If the error condition persists for longer than 15 seconds,
the welding process will abort. If the voltage goes down below 170 volts,
the welding process will be aborted immediately.
