ADVANCEMIG 350 • ADVANCEMIG 500
Controls Explained
Overload/ Error Indicator (6)
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 disa-
bled 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.
Power Source Display Meter (8)
Displays value for parameter adjusted by control
knob (21). During welding, displays welding current
or voltage depending on welding mode.
MMA Hot Start (9)
MMA mode only, provides extra power when the
weld starts to counteract the high resistance of the
electrode and workpiece as the arc is started. Select
by pressing parameter control knob (21) and adjust
by turning knob(10) Adjust welding current for MMA
and TIG welding modes. Select by pressing param-
eter control knob (21) and adjust by turning knob.
MMA Arc Force (11)
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. Select by
pressing parameter control knob (21) and adjust by
turning knob.
Down Slope (12)
When the trigger is released, the welding current will
reduce gradually over the time selected down to 0.
This allows the operator to complete the weld without
leaving a ‘crater’ at the end of the weld pool. Select by
pressing parameter control knob (21) and adjust by
turning knob.
Mode Control Button (19)
Selects MIG (13), MMA (14), MMA VRD (15), lift TIG
(16) mode.
2T/4T selector button (20,36)
2T mode the trigger is pulled and held on to activate
the welding circuit, when the trigger is released, the
welding circuit stops. 4T is known as ’latching’ mode.
The trigger is pulled once and released to activate the
welding circuit, pulled and released again to stops the
welding circuit. This function is useful to longer welds
as the trigger is not required to be held on continu-
ously.
Wire Feeder LH Digital Display
Before welding, displays synergic program number
(P), welding voltage (V), crater voltage or stitch weld
time (S), depending on the parameter being adjusted.
During welding, displays welding voltage. The pa-
rameter displayed is indicated by the LED below the
display.
Wire Feeder RH Digital Display (31)
Before welding, displays wire feeding speed, crater
wire speed or current, depending on the parameter
being adjusted. During welding, displays welding cur-
rent. The parameter displayed is indicated by the LED
below the display.
Water Cooling System Error Indicator (32)
When using the integrated water cooler, the system is
equipped with a pressure sensor. If the coolant pres-
sure is insufficient, this indicator will light and the
welding output will not be able to be active, in order
to protect the torch and cooling system.
Spool Gun Indicator (33)
lights when the spool gun switch is activated.
