The operating point is set with the wire speed and arc length rotary dials.
The operating point setting can also be specified using accessory components such as remote control,
welding torch, etc.
5.7.6.3
Setting the operating point (welding output)
The M3.77 control works according to the twin-knob operation principle. To set the operating point, only
the wire speed and the welding voltage need to be set according to the material and the electrode
diameter.
