Control Panel Features
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 wire feed control on these Raptor machines are
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 15 for a complete explanation of the function of
inductance. Inductance on these Raptor MIG machines 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
shielding gas.
