"duty cycle" = 50%
At the same time, the unit will react in such a way that while maintaining the
specified pulse difference, the average welding current level will be maintained at the level
of the set main value of the welding current 60A (as it was set earlier), respectively, and the
heat input into the weld will be approximately at the same level 60A, but stability the welding
process and the mixing of the weld pool will change. This is a very important condition for
accurate user assessment of the quality of change with equal heat input into the weld pool.
These parameters are set in different situations in different ways, according to the
welder’s requirements.
See paragraph 6.1 to change the value of any function in the current welding mode
4. TUNGSTEN-ARC INERT-GAS (TIG) WELDING
Caution! The default welding cycle set is
TIG-2T, see paragraph 4.2.1.
As a shielding gas, pure argon "Ar" is most often used, sometimes helium "He", as
well as a mixture of them in various proportions of 40% Ar + 60% He.
DO NOT allow the use of flammable gases! Use of other gases is allowed only in agreement
with the equipment manufacturer.
Caution! For continuous currents over 150A, be sure to use a water-cooled torch!
Sold separately together with a cooling unit!
Caution! A tungsten electrode needs to be sharpened to a "needle", and a common
mistake is sharpening an electrode to a "tip", 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 ca n
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.
