4. "Rise time" – time of current rise – 1 s.
5. "Main current" – main welding current – 100 А .
6. "Fall time" – 1 s.
7. "Finish current" – 30 А .
8. "Postflow" – time after blowing – 5 s.
9. "Pulse balance" – balance of pulses shape – 50%.
10. "Pulse frequency." – 50 Hz.
11. "Low current" – lower current of pulsed mode – 50 А .
12. "Pulse mode" – pulsed mode, ON.
Pay attention!! In order to activate the pulsed mode, it is necessary to change the value of
the "Pulse mode" parameter to "ON", after which the indicator 8 must change the value to
"P" (pulsed mode is on). After that the welding can be started. The value of acting welding
current will range from 50A to 100 A with a periodicity of 50 oscillations per 1 second.
These parameters are set in different situations differently according to the
requirements of the welder.
4.3 TIG Lift function of arc ignition
This function is used mainly in the cases where there are electric appliances sensitive to
electromagnetic oscillations near the welding area, which can disable the unit of
contactless arc ignition or oscillator, because it generates a powerful high-frequency
electric discharge at the moment of arc ignition.
If TIG Lift function is activated, then the unit of contactless arc ignition will be switched
off and to ignite the arc it is necessary to touch the product with the tungsten electrode.
4.4 Double Pulse function
This function combines conventional low-frequency pulsations of welding current with
automatic high-frequency current pulsations. This makes it possible to improve the quality
and appearance of the weld, to protect the product from overheating, as well as to increase
the efficiency of TIG welding process by increasing the speed of passage. This function is
used when welding thin-walled parts and products of corrosion-resistant austenitic grades
of steels sensitive to overheating, as well as in cases when increased requirements for the
appearance of the weld are specified.
4.5 SPOT welding mode
SPOT – is the mode of welding in spots or in short welds.
This is TIG-welding with a fixed parameter - "Spot time", that allows the welder to
produce many similar spots or welds.
Let us consider the example. Let us set the mode:
- “ Button mode ” – 2Т ;
- “ Preflow ” – 1 s;
- “ Pulse time ” – 0.1 s;
- “ Pause time ” – 3 s;
