23BOC Smootharc Advance MIG 200C/275C/275R/350R Operating manual
8.2 Remote models
The easy-to-operate and understand machine front panel includes two
LED displays for welding voltage and current/wire feed speed.
Torch latching
This is obtained by using the scroll button on the machine front face.
Wire feed motor speed range adjustment
The operating parameters of the wire feed motor can be altered by
switching to low or high speed range using the scroll button on the front
panel of the machine.
Gas Purge
The gas purge allows setting of the gas flow rate without the wire
feeding through the wire feed unit. This can also be used to purge the
system prior to the start of welding or after shutdown to ensure that no
shielding gas is trapped within the system.
Remote Wire feed front panel
The controls situated on the wire feeder allows the operator full
control over the welding parameters without having to go back to the
power source.
Wire inch control
This control will feed the wire at a rate of 11m per minute through the
wire feeder without activating the gas solenoid of the power source
eliminating wastage of shielding gas.
By holding the button down it enables the operator to inch the wire
through the torch without having to depress the trigger.
This is also a safety feature because, if the operator uses the trigger on
the torch to feed the wire through, the welding current will also be on.
When the wire exits the torch it may make contact with the work piece
and cause an arc flash. This is injurious to exposed eyes and skin. It also
allows the wire to be feed through without the shielding.
Voltage adjustment
The inverter power source allows infinite adjustment of welding voltage
even when the arc is struck.
Wire speed/amperage
The wire feed control adjusts the speed that the wire is fed through the
MIG torch. The BOC Smootharc ADVANCE wire feed control is stepless
which means it can be adjusted whilst welding. This is an excellent
feature with these machines because the operator can set the ideal
parameters when welding. The higher the wire feed speed the higher the
amperage of the machine.
Inductance
Refer to page 24 for a complete explanation of the function of
inductance. Inductance on the BOC Smootharc ADVANCE machine can
infinitely be adjusted.
Changing the inductance will have an enhancing effect on both spatter
and weld bead appearance during dip transfer. Virtually spatter free
welds can be obtained even when using 100% CO
2
as a shielding gas.
