Operation instruction under LIFT TIG mode.
1
When welding stops, press the
【
STICK/LIFT TIG/MIG switch key
】,
the LIFT TIG indicator lights up
,
and it
turns into LIFT TIG mode. LIFT TIG means the tungsten contacts the workpiece first, then press the torch
switch, the arc is ignited by lifting the torch.
2
Under LIFT TIG mode, press
【
VRD/2T/4T switch key
】
to choose the welding mode, which displays as Chart
5. 2T NORMAL lighting up means 2 step control way: press the torch switch, open the shielded gas, and start
the main circuit, lift up the arc, the welding current increases till to a steady-state value. While, 4T LATCH
lighting up means 4 step control way: press the torch switch for the first time, open the shielded gas, and start
the main circuit, lift up the arc, and ignite it; then release the torch switch, the machine outputs steady current.
Press the torch switch for the second time, the welding current attenuates until to crater value and keep on,
then release the torch switch again, the arc quenches soon and the welding stops.
Chart5: The preset current under LIFT TIG mode
3
【
multifunctional data display
】
shows the preset current“080
A
”, its unit is ampere(A).
4
Adjusting the
【
Multifunctional data adjusting knob
】
can change the welding current during welding process,
and display in
【
multifunctional data display
】
. The welding current range is 10A-175A.
5
3 seconds later after setting the welding parameters, the
【
multifunctional data display
】
would flashes for one
time, which means the data has been saved. Moreover, the panel would display these data when restart the
machine next time if the parameters keep unchanged.
6
The panel displays as Chart 6 when perform welding, which means the welding voltage is 17.2V, and the
preset current is 80A.
7
Releasing the torch switch and stopping welding, the panel displays as Chart 7. Moreover,“HOLD” flashes for 3
seconds and quenched, which means the welding stops. 2 seconds later,
【
multifunctional data display
】
redisplays the preset current.
Note
:
The machine adopts touched ignition way when perform welding under TIG mode. Firstly make sure the
tungsten contacts the workpiece completely, then press the torch switch, lifting up the torch to ignite arc
successfully.
