9.1 Starting up
Switch on the welding power source. The front panel display will light
up. After the Multifunctional data display
1
(or any key or knob on front
panel
2
–
6
) flashes for 5 seconds, the machine enters into the welding
mode that was saved in the last shutdown.
9.2 Operation for MMA mode
Press the MMA/LIFT TIG/MIG switch
2
to MMA. The MMA indicator light
will illuminate.
7
In the MMA mode, press the VRD (Voltage Reduction Device)/2T/4T
4
switch. The VRD reduces open circuit voltage to a safe limit and the
function is enabled when the indicator light is on.

Multifunctional data display
1
shows the preset current (A) 80A shown
in figure 2.
Adjusting the Multifunctional data adjustment
6
will change the welding
current during the welding process. The welding current range is
10-175A.
Three seconds after changing the welding parameters, the
Multifunctional data display will flash once to indicate that the setting
has been saved. If the parameters are unchanged this setting will remain
as such even after restarting the machine.
The machine has the ability to display the arc voltage during MMA
welding (23.2V at 80A as shown in figure 4). The arc voltage will only
be displayed during welding and for five seconds after completion
of welding when the display will revert back to the preset display
amperage.

9.3 Operation instruction under LIFT TIG mode
Press the MMA/LIFT TIG/MIG
2
switch to LIFT TIG. The LIFT TIG indicator
light will illuminate.
7
The welding mode (2T/4T) can be selected by depressing the VRD/2T/4T
4
. The selected mode will illuminate.

The figures above indicate that the LIFT TIG mode and 2T NORMAL has
been selected.

The welding amperage can be adjusted by turning the Multifunctional
data adjustment.
6
In the figures above it is selected at 80A.
Welding amperage can be adjusted whilst welding and the welding
current range is 10–175A.
If settings are unchanged for three seconds the Multifunctional data
display
1
will flash once to indicate that the setting has been saved and
these will be retained, and displayed when the machine restarts.
9.4 Data selection
Data selection (effective under MIG mode)
→
Multifunctional data adjustment
If you want to make coarse adjustments press and turn the knob
6
this
will rapidly increase the regulating rate and wire speed
For fine adjustments only turn the knob.
6
This will slowly increase the
regulating rate and wire speed.
9.5 Polarity selection
The polarity on this machine can be reversed if so required for certain
types of self-shielded wires. This can be achieved by switching the work
return lead from the positive (+) to the negative (–) dinse socket.
