MIG/MAG operating point
The operating point (welding power) is specified using the MIG/MAG one-knob operation principle, i.e. the
user can specify either the welding current, the wire feed speed or the material thickness to define the
operating point. The electronic system calculates the optimal required welding voltage value.

Application example (setting via material thickness)
The required wire feed speed is not known and is to be determined.
• Select welding task JOB 76(
> see 5.3.5 chapter
): material = AlMg, gas = Ar 100%, wire diameter =
1.2 mm.
• Switch the display to material thickness.
• Measure the material thickness (workpiece).
• Set the measured value, e.g. 5 mm, at the machine control.
This set value corresponds to a specific wire feed speed. Switching the display to this parameter will
show the associated value.
In this example, a material thickness of 5 mm corresponds to a wire feed speed of 8.4 m/min.
The material thickness details in the welding programs generally refer to fillet welds in the PB welding
position. They should be regarded as guideline values and may differ in other welding positions.
