3.4.6 Synergic/Manual
Synergic
The welding voltage varies with the welding current. The procedure is as follows:
1. Press the Manual button on the control panel and rotate the voltage adjusting knob on
the wire feeder to set the standard voltage to 30 V.
2. Press the Synergic button on the control panel and perform welding in synergic
mode.
