speed. Under pulse MIG, welding voltage and pulse parameters can be also automatically selected by
adjusting wire feed speed.

“Inductance” button on the panel is adjusted to realize soft or hard welding arc characteristic; when it
is rotated anticlockwise, arc becomes hard with low inductance and explosive arc; when it is rotated
clockwise, arc becomes soft with high inductance and less spatter. In general, “inductance” button is
adjusted to the middle and then is trimmed according to welder process requirement. Under mini
current, hard characteristic will be favorable, while soft characteristic will be favorable under max
current.

7.2.5.2. 4T operation mode
When torch trigger is pressed to ignite arc, welding begins and continues to work even if torch trigger is
released (“current adjusting” and “voltage setting” knobs on wire feeder can adjust welding condition); When
torch trigger is pressed again, stopping arc is effective (
“welding/crater current” and “arc-force/crater voltage”
knobs on the front panel can adjust welding condition). At this time, ammeter and voltmeter display actual
current and voltage respectively. Welding stops when torch trigger is released.
