GB
When the mains switching device is turned on, the diode (H) goes on.
When open circuit voltage is applied diode (J) goes on.
When an error occurs, for example overheating, diode (L) goes on.
When there is no water flow diode (M) goes on.
When there is a fault that can cause temporary high output voltage, the LED
switches off (J), (output voltage has been switched off). When idling for longer than
30 minutes, the output voltage is switched off and diode (J) goes out.
Restart by turning the switch (1) to TIG mode and then back to MMA mode.
6.2

Remote control unit

For both the TIG and MMA methods the welding current can be adjusted by way of a
remote control unit. The welding power source registers automatically when a
remote control unit is connected.
If the remote control is to include the whole current range, the current must be set to
max. on the welding power source.
Max. value = The reference value set on the welding power source.
6.3

Protection against overheating

Three thermal cut−outs prevent the power source being overloaded as a result of too
high temperature. If this should happen, the welding current is interrupted and the
yellow diode (L) goes on. (See page 7.)
When the temperature has gone down, the welding current circuit is reclosed and
the diode goes out.
