3.2.2 MMA AC/DC display introduction
1.
Welding mode button
: Press it to select Stick DC or Stick AC welding mode.
2.
L parameter knob
: Turn it to welding current.
3.
R parameter knob
: Press it to select Hot Start or Arc Force and turn it to adjust values.
Hot start
Hot start provides extra power when the weld starts to counteract the high resistance of the
electrode and workpiece as the arc is started. Setting range: 0~10.
Arc force
An MMA welding power source is designed to produce constant output current. This means with
different types of electrode and arc length; the welding voltage varies to keep the current
constant. This can cause instability in some welding conditions as MMA welding electrodes will
have a minimum voltage they can operate with and still have a stable arc.
Arc Force control boosts the welding power if its senses the welding voltage is getting too low.
The higher the arc force adjustment, the higher the minimum voltage that the power source will
allow. This effect will also cause the welding current to increase. 0 is Arc Force off, 10 is maximum
Arc Force. This is practically useful for electrode types that have a higher operating voltage
requirement or joint types that require a short arc length such as out of position welds.
