7.2.3 LIFT TIG
Open the gas valve on the TIG welding torch.Touch the tungsten electrode to the work piece
for less than 2 seconds and pull away approximately 2mm to start the arc. Alternatively, the
arc can be started by scratching the tungsten electrode on the work piece and moving it
away to around 2mm.
After welding, pull off the arc by raising the welding torch.
Close the gas valve on the TIG welding torch.
LIFT TIG mode has no torch switch operation mode.

LIFT TIG process
NOTE! When starting the arc if the short-circuit time exceeds 2 seconds the welder
turns off the output current. Lift the welding torch. Restart the process as above (7.3.2)
to start the arc again.
NOTE! During welding, if there is short circuit between tungsten electrode and the
work piece, the welder will immediately reduce the output current; if the short circuit
exceeds 1 second, the welder will turn off the output current. If this happens, the arc
will need to be restarted as above (7.3.2). and the welding torch needs to be lifted to
start the arc again.
7.2.4 Turn off the power supply after welding
(As above 7.1.6)
