If no current zero crossing is measured after a certain time when activating the welding transformer (polarity rever-
sal of the full bridge inverter), the system stops with E32-02 “Timeout”.
Especially with the MicorMIG 500, the current direction of the primary current sensor must be set to the correct
mounting position:
The black connecting lead of the sensor must point in the direction of the cable shoe of the transformer lead. If the
sensor is mounted incorrectly (rotated by 180 °), this would also result in fault message E32-02.
