Code Error

An erroneous input has occurred, a code tag is poor or has
an error in code symbology or code reading was improper.
11.1.2

No Contact

There is no properly established electric contact between
the welding unit and the fitting (check push-on terminal on
fitting), or the heater coil is defective.
11.1.3

Low Voltage

The input voltage is below 175 volts. Adjust generator out-
put voltage.
11.1.4

Overvoltage

The input voltage is over 290 volts. Decrease generator out-

operated and has to be sent to an approved shop for check
and repair.
11.1.7

Temperature Error

The ambient temperature measured is outside the operat-

Temperatur Sensor Defective

The ambient temperature sensor on the welding cable is
