Further Controls Explained
Overload/ Error Indicator
Lights when over voltage, over current, input phase
loss or electrical overheating (due to exceeding duty
cycle) is detected and protection is activated.
When protection is activated, welding output will be
disabled until the safety system senses the overload
has reduced sufficiently and indicator lamp goes out.
May also trigger if machine experiences an internal
power circuit failure.
Arc Force Control Knob
An MMA welding power source is designed to pro-
duce constant output current (CC). This means with
different types of electrode and arc length; the weld-
ing 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 use-
ful 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.
Hot Start Control Knob
Hot start provides extra power when the weld starts
to counteract the high resistance of the electrode and
workpiece as the arc is started.
Lift TIG Mode
Lift TIG is an arc ignition system for basic TIG weld-
ing that removes the need to ‘scratch’ start or strike
the tungsten on the work piece to start the arc, which
can have a negative effect on the weld quality due to
tungsten contamination. Lift arc starting works by
gently touching the tungsten on the work piece and
then lifting it off. The control circuit will sense when
the tungsten is removed from the work piece and
send a pulse of electricity through the torch that will
cause the TIG arc to initiate.
