5.10.5 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.
5.10.5.1 Selecting the display unit
Figure 5-15
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).
5.10.5.2 Operating point setting using material thickness
Given below is a description of the setting work via the wire speed parameters as an example of
operating point setting.
