BB - LED HOLD
This lights up automatically at the end of the welding process, displays AR and AS show the most recent measured
arc current and voltage values.
BD - JOB retrieval key
Press key BD to call up the JOB function (see section 7). They can be selected by turning knob AW
BC - LED JOB
This lights up when the JOB is selected
BE - LED Remote control
This lights up when a remote control is connected to connector E of the wire feeder (see section 3.8).
BG - LED Cooling unit
This lights up when the cooling unit is activated (see section 7.3.1)
BF - Wire Rewind key
When this key is pressed, the motor rewinds the wire by a few centimetres without any voltage and welding gas in
the torch.
BH - Wire Feed key
When this key is pressed, the motor feeds the wire, without any voltage and welding gas in the torch.
BL - Gas test key
When this key is pressed, the gas fl ows out for 30 seconds. If pressed again during gas fl ow, the fl ow stops.
