5.10.4 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.
5.10.4.1 Selecting the display unit
The operating point (welding performance) can be displayed as the welding current, material thickness or
wire speed.

Example application
You are welding aluminium (material= AlMg, gas= Ar 100%, wire diameter= 1.2 mm and 5 mm material
thickness), you don’t have any specifications and do not know the required settings, e.g. for the wire
speed.
Switch to the material thickness display. Set the operating point to 5 mm.
This corresponds to a wire speed of 8.4 m/min, for example.
