5 OPERATION
5.9
Remote control
Connect the remote control on the rear side of the power source and activate the
remote control by pressing the remote control button on the panel (remote control
indicator being lit when activated). When the remote control is activated the control
panel is locked for interaction but displays welding data.
Should a remote device be connected the maximum output current of the power
source will be determined by the front panel control knob, irrespective of the remote
control device setting.

Functions and symbols
MMA welding
MMA welding may also be referred to as welding with coated electrodes. Striking the
arc melts the electrode, and its coating forms protective slag.
For MMA welding the power source shall be supplemented with:
•
welding cable with electrode holder
•
return cable with clamp
Arc force (Hidden function)
The arc force function determines how the current changes in response to variations in
arc length during welding. Use a low value of arc force to get a calm arc with little
spatter and use a high value to get a hot and digging arc.
Arc force only applies to MMA welding.
Hot start (Hidden function)
The hot start function temporarily increases the current in the beginning of the weld.
Use this function to reduce risk of insufficient fusion and electrode sticking and
scratching.
Hot start only applies to MMA welding.
TIG welding
TIG welding melts the metal of the workpiece, an arc initiated from a non-consuming
tungsten electrode. The weld pool and electrode are protected by shielding gas.
For TIG welding, the welding power source shall be supplemented with:
•
a TIG torch
•
an argon gas cylinder
•
an argon gas regulator
•
tungsten electrode
This power source performs LIFT TIG start.
The tungsten electrode is placed against the workpiece and press the torch trigger.
When lifted away from workpiece the arc is struck at a limited current level.
