4.6 WELDING CURRENT BUILD-UP FUNCTION
This function, in addition to saving the life of the electrode and, to some extent, the
torch itself, is also necessary for the convenience of using the torch. This eliminates the
formation of the initial splashing of the weld pool, as well as for the set time of current build-
up (in the case of the TIG-2T button mode), you can accurately direct the torch to the desired
welding location, since the arc striking location in particularly critical workpieces is not
always located at the welding location, or you can even use this function to preheat the
welding location. By
default, it is in the “OFF” position, i.e., the function is disabled.
See paragraph 6.1 to change the value of any function in the current welding mode
4.7 RAMP-DOWN FUNCTION
This function is necessary to improve the process of filling the crater formed under
the pressure of the main working current of the welding arc, and such a crater is the nucleus
of weld defects, i.e. it is an extremely negative phenomenon. Therefore, for the set time of
the current ramp-down, it is possible to weld the formed cavity.
By default, it is in the “OFF”
position, i.e., the function is disabled.
See paragraph 6.1 to change the value of any function in the current welding mode.
4.8 CRATER FILLING CURRENT FUNCTION
This function is necessary to indicate the level to which the current drops at the end
of the welding process. It is necessary for crater filling in the TIG-4T button mode (with the
second press of the torch button). By default, the crater filling current is set at 20A.
See paragraph 6.1 to change the value of any function in the current welding mode.
4.9 SHIELDING GAS POST-PURGE FUNCTION
This function consists in the post-purging of the welding zone with a shielding gas
after the welding arc is extinguished, since the hot weld pool is afraid of the harmful effects
of atmospheric air for some time. By default, the post-purge time is set to 3.0 seconds; this
value can be changed at any time at your discretion.
See paragraph 6.1 to change the value of any function in the current welding mode.
4.10 PULSE CURRENT WELDING FUNCTION
This function is designed to facilitate the control of the welding process in spatial positions
other than the lower one, as well as when welding non-ferrous metals. The effect occurs
directly on the mixing of the molten metal of the seam, and this, in turn, on the stability of
the seam formation. To some extent, it replaces the movement of the welder's hand during
welding, especially in hard-to-reach places. There is also partially a forced effect on the
transfer of a drop from the filler wire to the weld pool. The shape and quality of the weld
formation depends on the correct setting, which reduces the likelihood of the appearance of
pores and reduces the grain structure, and thus increasing the strength of the weld.
To implement this function in the unit, you need to set three parameters: pulsation power,
pulsation frequency and pulse/pause ratio (or "duty cycle") [dut]. By default, the pulsation
