be operated and has to be sent to an approved shop for
check and repair.

9.1.6 Clock Error

The internal system clock works improperly or is defective.
Reset it, or send the welding unit to the manufacturer for
check and service.

9.1.7 Input Error

At manual welding parameter input, no welding time was
entered. An incorrect value was selected in the date set-
ting.
9.2

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. If the error condition
persists for longer than 15 seconds, the welding process
will be aborted. If the voltage goes down below 170 volts,
the welding process will abort immediately.

9.2.2 Overvoltage

The input voltage is over 290 volts. If the error condition
persists for longer than 15 seconds, the welding process
will be aborted.

9.2.3 Frequency Error

The frequency of the input voltage is out of tolerance
(42 Hz - 69 Hz).

9.2.4 Voltage Error

Check generator voltage and current. The output voltage
does not correspond to the value previously read; the weld-
ing unit has to be sent to the manufacturer for check-up.

9.2.5 Low Current

The message is displayed if the there is a momentary cur-
rent failure or if the current decreases by more than 15%
per second for 3 seconds.

9.2.6 High Current

The output current value is in excess; possible causes: short-
circuit in the heater coil or the welding cable. During the
start stage the upper abort threshold equals 1.18 times the
