MIG/MAG operating point

The operating point (welding output) is specified using the principle of MIG/MAG one-dial operation, i.e.
the user need only specify the operating point by setting the required wire speed, for example, and the
digital system will calculate the optimum values for welding current and voltage (operating point).
The operating point setting can also be specified using the accessory components such as the remote
control, welding torch, etc.
5.5.5.1

Selecting the display unit

The operating point (welding performance) can be displayed as the welding current, material thickness or
wire speed.

Application example
Aluminium is to be welded.
•
Material = AlMg,
•
Gas = Ar 100%,
•
Wire diameter = 1.2 mm
The correct wire speed is not known and is to be determined.
•
Select the appropriate JOB (- See 11.1 JOB-List chapter)
•
Switch to the material thickness display
•
Set the material thickness as appropriate (e.g. 5 mm)
•
Switch to the wire speed display
The resulting wire speed will be shown (e.g. 8.4 m/min).
