Front Panel Functions and Descriptions
1.2.1 MMA control panel
1. Welding mode button: Press it to enter MMA welding mode.
2. L parameter knob: Rotate it to welding current.
3. R parameter knob: Press it to select Hot Start or Arc Force and rotate 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 cur-
rent. 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 mini-
mum 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 posi-
tion welds.
