X8 MIG WELDER
2.4 Operation
Using W
W is a synergic MIG/MAG process optimized for open-gap root pass welding. The process is based
on precise measurement of voltage between the welding gun nozzle and the workpiece. The measurement
data serves as input for the current control. The process is suitable for root pass welding in all positions, and
provides a smooth and spatter-free arc.
To adjust the welding power / wire feed speed, in the Control Pad's
Welding
view, turn the left knob.
To fine tune the heat while welding, in the Control Pad's
Welding
view, turn the right knob.

Parameters
:
• Wire Feed Speed
• min: adjusts the minimum set value for wire feed speed
• max: adjusts the maximum set value for wire feed speed
• Fine tuning: adjusts the heat of the arc.
• Dynamics: -10...+10. Adjusts the short circuit behavior. On the minus side, the arc is softer. On the plus
side, the arc is harder.
• StartPower: -30...+30. Adjusts the power level for arc ignition.
• StartLevel: -30...+30. Fine tunes the arc length for arc ignition.
• StopPower: -30...+30. Adjusts the power level for arc stop.
Using W
W is a synergic MIG/MAG process whose short-arc features are optimal for welding sheet metals
(plate thickness 0.8 - 3.0 mm). It is based on precise measurement of voltage between the welding gun
nozzle and the workpiece. The measurement data serves as input for the voltage control. The process
reduces heat input, deformation and spatter. W is also optimal for position welding with thicker
plates.
To adjust welding power / wire feed speed, in the Control Pad's
Welding
view, turn the left knob.
