- put the automatic switch 6 on the rear panel to the ON position;
- use button 4 to set the TIG welding mode, the modes are switched in a circle;
- use buttons 2 to set the current main parameter, this is the welding current;
- if necessary, you can adjust additional functions of the welding process, see paragraph
6.1 for the order of switching.
Caution! The TIG torch must be of valve type, with a Ø 13mm bayonet connector. Choose
the maximum torch current according to your operating requirements.
Caution! A common mistake is to sharpen the electrode to a "needle", while the arc can
“ wag ” from side to side. The correct sharpening is a slightly blunted tip, and the fewer are
the “ needle butts ” that can withstand the set current, the better. Keep in mind that at high
welding currents, a very sharpened electrode is easily melted due to low heat transfer. Also,
the
“ stripes ” from sharpening should be located along the axis of the electrode.
4.1 WELDING PROCESS CYCLE - TIG-LIFT
See paragraph 6.1 for the procedure for switching the value of any function
4.2 TIG-LIFT ARC STRIKING FUNCTION
This function is set by default in this model of equipment, and is designed for torches
with contact arc striking, without using oscillators and other similar units, but unlike the
classic method, it completely eliminates the shock current at the time of striking. This
function significantly reduces the destruction and ingress of a refractory tungsten electrode
into the welding seam, which is a very negative phenomenon.
Caution!!! The workpiece needs to be cleaned at the place of arc striking.
How to use this function is to touch the workpiece with the electrode, while you can
hold the electrode in this position indefinitely, and when the user considers that he is ready
to start welding (e.g., he lowered the protective mask over his eyes and blew the place well
with shielding gas) then it is enough to start SLOWLY lifting the sharpened electrode tip
away from the workpiece. The unit will detect this moment and perceive it as a signal to
start the welding process, thereby starting to increase the welding current to the set value.
The larger the main operating current, the faster you need to raise the electrode,
otherwise, it will melt. You need to get used to the optimal electrode separation speed. The
time of smooth current build-up [t.uP] to the set value will be reviewed in the next
paragraph.
