Description
1. Power on warning. Green light when the machine is connected and switched on.
2. Thermal protection activated. Yellow light indicates that the protection thermostat has cut the
output. Do not switch the machine off. The fan will be running and the thermostat resets
automatically when the machine has cooled down sufficiently. The light will darken when the
machine is live again.
3. Selection of welding process:
Up:
SMAW (MMA) welding with stick electrodes
Middle: TIG (GTAW) pulse welding
Down: TIG (GTAW) welding.
4. Welding current adjustment potmeter. Rotate knob clockwise to increase amperage,
minimum to 150 Ampere
5. Active VRD signal. When lit this shows that the Voltage Reducing Device is active, reducing
the voltage across the welding sockets. This will happen within 2 seconds after the welding
arc is broken to protect the welder from electric chock.
Full arc striking voltage will automatically be re-established when the welding circuit is re-
established by touching the electrode to the work-piece
6. On/Off switch (Back panel)
7. Primary cable, 3 core 2,5mm², 2,5m long
.
8. When lit this warning light indicates that the
Total Protection function has been activated and
input power has been cut because it has
exceeded 285V ac.
