4.2 PRECURRENT FUNCTION (PILOT ARC)
This function is required for the convenience of the torch when the arc is ignited. It allows
the welding process to be started at low currents, the value of which only maintains the
process but does not introduce significant heat input and does not burn the workpiece. When
using the TIG-4T button mode, it is possible to preheat the welding area. By default, the
preheat current [Pr.A] is set to 20A.
To change the value of any function in current welding mode, see paragraph 6.1
4.3 CRATER FILLING CURRENT FUNCTION
This function is necessary to indicate the level to which the current decreases at the end of
the welding process. It is necessary for crater filling if the TIG-4T pushbutton mode is used
(with a second press of the torch button). By default, the crater filling current is set to 20A.
To change the value of any function in the current welding mode, see paragraph 6.1.
4.4 CURRENT RAMP-UP FUNCTION
The function was developed to save the life of the tungsten electrode as well as the TIG torch
itself. It eliminates the formation of the initial weld pool spatter, as well as the set time of the
smooth current rise time
[t.uP]
, in the case of the TIG-2T push button mode, the torch can
be accurately directed to the desired welding spot, since the point of arc ignition in
particularly critical workpieces is not always at the welding spot. This function can also be
used to preheat the welding spot.
By default it is set to OFF - inactive. To change the value of any function in the current welding mode, see section 6.1.
4.5 CURRENT RAMP-DOWN FUNCTION
This function is necessary to improve the process of filling the crater formed under the
pressure of the main welding arc current, and this crater is the beginning of welding defects,
which is an extremely negative effect. Therefore, for the set current decrease time [t.dn] it is
possible to weld a formed cavity in the weld. By default it is set to OFF - inactive.
To change the value of any function in the current welding mode, see Section 6.1.
4.6 PULSE CURRENT WELDING FUNCTION
In the TIG welding method using pulsed current, the current switches between a high level
called "peak current" and a low level called "base current". This switching allows for better
control over the heat during the welding process. By managing the heat more precisely,
potential distortions in the workpiece, especially in thin materials or delicate parts, can be
reduced.
When compared to continuous current welding, this pulsing method results in less spatter,
making the final weld cleaner and more visually appealing. The "peak current" phase ensures
deep penetration into the materials, leading to strong and lasting welded connections.
