ADVANCEMIG 350 • ADVANCEMIG 500
Overload/ Error Indicator (34)
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.
Water/ Air Cooling Selection Button (35)
When using the integrated water cooling system with
a water cooled torch, select the ‘water’ option. This
will activate the water cooler power (the water cool-
er must also be switched on the rear panel) and the
water cooling protection system. If using air cooled
torch, select ‘Air’ option.
Note: The ADVANCEMIG 500 comes standard with a
watercooled torch system. Operating a water cooled
torch without water cooling will quickly cause serious
damage to the torch.
MIG Parameter Selection Button (37)
This button selects the following welding parameters,
which are displayed on the LH display (30) and ad-
justed using the LH control knob (40).
Gas Pre Flow
Controls the period shielding gas will flow for when
the torch is triggered before the arc starts. This purg-
es the work area of atmospheric gas which could con-
taminate the weld before the weld starts.
Gas Post Flow
Controls the period of time the shielding gas contin-
ues to flow for after the arc is stopped. This protects
the weld area from contamination while it is still hot
enough to react with atmospheric gases, after the
weld is finished.
Soft Start
Sometimes known as ‘hot start’. When a weld is start-
ed, the workpiece and the wire will be ‘cold’ compared
to welding temperature, this can cause an uneven and
poor start to the weld using the voltage and wirefeed
speed selected as optimal once the arc is established.
This setting slows the wire speed down at the start
of the weld which improves the weld starting perfor-
mance.
Burn Back
Burnback adjustment controls the short period of
time that the wire feed will continue to run for after
the main welding current stops. If the wire feed and
current is stopped at exactly the same time, the wire
will still be hot and ‘burn’ back and stick to the weld-
ing tip. If this problem is happening, increasing the
burnback adjustment will cause the wire feeder to run
for longer after the arc has stopped. If the burnback is
adjustment is excessive, after a weld is stopped, the
operator will be left with excess ‘stickout’ wire length
from the torch tip that will require correcting before
starting the next weld.
MIG Wave Control/ Inductance Knob (38)
This setting changes the MIG waveform to simulate
changing the inductance of the welding circuit. In-
ductance controls the rate of the current rise and fall
as the welding wire contacts the workpiece (known as
a short circuit). More inductance increases the short
circuit time and decreases the short circuit frequency
rate. This causes a wider and more penetrating arc,
useful for thicker weld joints. Less inductance will
create a narrow more focused arc. This effect can
also be used to fine tune the arc to produce less splat-
ter. Wire speed, wire size and type, shielding gas will
all change the effect that the inductance setting has
on the welding arc. Inductance change will have no
practical effect on MIG spray transfer process (as op-
posed to short circuit process).
RH MIG Parameter Adjustment/ Selector
Knob (39)
Control parameters displayed on the RH display
screen (31). Pressing the knob will switch between
parameters displayed.
LH MIG Parameter Adjustment/ Selector
Knob (40)
Control parameters displayed on the LH display
screen (31). Pressing the knob will switch between
parameters displayed.
