Main switch and 'ON' indicator
When you turn the main switch to position I, the indicator light is illuminated and the unit is
ready for welding. The indicator light is always on when the unit is connected to the mains
and the main switch is in position I.
Always start and stop the machine from the main switch, never use the plug as a switch!
NOTE!
Indicator 'VRD safe ON'
VRD active units reduce the open circuit voltage to a lower level. The indicator is illuminated
when the circuit is activated and the unit is in working order.
Welding process selector, MMA/TIG
This switch is used for selecting either MMA or TIG welding mode, depending on the welding
process chosen.
Regulating welding current
The welding current level is regulated via a stepless adjustment knob. Set the welding current
level according to the target weld piece, position and electrode type and size.
Overheating indicator
The thermostatic temperature switch may become active during heavy welding or high
ambient temperatures. This is indicated by a yellow indicator light. The power source fan will
cool the unit and after the indicator goes off, the unit is again ready for welding.
Local and remote control
The welding machine can be controlled with a remote control device. Select remote control
by pressing the Remote control ON/OFF button.
Details of available remote current control devices can be found in the Ordering codes section
later in this manual.
