K1
0000
Digital ammeter
Displays the welding current at all times.
L1
Red LED collective interference
If the collective interference LED lights, the power unit is automatically switched
off. Because some interferences are only brief and spurious (e.g. mains voltage
surges), the LED extinguishes again and the welding machine is ready for
welding. If the collective interference LED continues to be lit after an appropriate
waiting time, see the chapter on troubleshooting.
M1
Red LED (water deficiency)
Indicates a water deficiency in water-cooled welding machines.
N1
Changeover switch for selecting the ignition modes
HF
HF ignition:
In HF welding, the arc is initiated without contact by a high-voltage ignition
pulse.
HF
Liftarc ignition:
In welding with Liftarc ignition, on the other hand, the Tungsten electrode is in
contact with the workpiece. The torch trigger is operated and a minimum current
flows. The torch is now removed from the workpiece, the arc ignites and the
welding current set flows according to the operating mode.
