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.

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

Parameter setting (setting range 0 to 499)
Wire back-burn set too high: large drops developing on the wire electrode result in poor
ignition properties or the wire electrode sticking to the welding nozzle.
Wire back-burn set too low: Wire electrode sticks in the molten pool
