Welding using TIG process
Device is equipped with a HF arc ignition allowing to start the arc without touching the working material
what reduces electrode wear to minimum.
In order to ignite the arc in the two-stroke mode, the electrode should be brought closer to the welded
material at a distance of 2 millimetres and press the button in the torch handle to turn on the ionizer. After
the correct initiation of the arc conduct the welding with button pressed. Releasing the button on the
handle will start phase of current downslope and completion of the welding process.
In order to ignite the arc in four-stroke mode, the electrode should be brought closer to the welded
material for a distance of 2 millimetre and press the button on the torch handle to turn on the ionizer.
After correct arc ignition you can release the button and conduct the welding with button released. To
finish welding you must press and release the button on the handle.

TIG welding in 2T mode
0:
Press and hold torch trigger. Shield gas starts to flow
0 ~ t1:
Pre flow
time
t1 ~ t2:
Arc ignition. Current begins to ramp from start current value to welding current value
t2 ~ t3:
Welding being conducted while holding the trigger.
t3:
Trigger has been released. Current is being reduced during downslope time
t3 ~ t4:
Welding current reached the lowest set value. Arc goes out
t4 ~ t5:
Shield gas post flow time
t5:
Shield gas valve has been closed. Welding ends.
