holder cable set in DC electrode negative mode. Connects to earth clamp
cable set in DC current electrode positive mode.
VRD function indicator light: When VRD is turned off in MMA mode, the
indicator light is off. When VRD is turned on, the indicator light is lit.
Current display: Output current is displayed in real time. While data is set,
the set values are displayed.
Error indicator light: When no abnormalities are present during operation,
the light will be off. The light will be lit if abnormalities occur during operation.
Voltage display: Output voltage, arc length and program channels are
displayed.
Arc force current adjustment: The function of the arc force is to eliminate
the phenomenon of electrode 'sticking' and is adjusted by rotating the knob.
VRD function: An ON/OFF switch which can regulate whether the VRD
function is active or not.
When turned ON, the open-circuit voltage of the machine is restricted to below
24V which reduces the shock risk in humid conditions, at high altitudes and
welding in confined areas and metal containers.
Remote control function: An ON/OFF switch regulating the remote control
function. The welding current can be adjusted remotely or turned off if not
required.
Welding current adjustment: The output current is adjusted by rotating the
knob.
