PROBLEM

POSSIBLE CAUSE OR

SYMPTOM

POSSIBLE FIX

Sensor cable disconnected.

Check to see if the sensor cable is properly connected to the
weld monitor.

Toroid disconnected or damaged.

Inspect the toroid for poor connections and/or physical damage
or abrasion. Reconnect, replace and/or relocate toroid if
necessary.

A-D Threshold setting is too
high/incorrect.

In the

General Setup Menu

, decrease setting until a weld is

detected.

WELD COUNT DOES
NOT INCREASE
