PATON StandardTIG DC MMA/TIG/MIG/MAG
immediately after the function of gas pre-purge of the welding zone for the time [t.Pr] starts
the process of arc striking - this is the same as in the 2T button mode. In this case, after
the
first release , the welding process continues unchanged. This mode is provided by PATON as
a bonus one, use it as desired, since it is more common from the point of view of more
frequent use of 2T mode by customers in conventional semi-automatic units, therefore, it is
more user-friendly.
5.3 INDUCTANCE FUNCTION
This function is required to change the rate of current build-up when the arc voltage
changes. As a result, spatter is reduced, but it also affects the drop transfer process, which
at high inductance values leads to a slowdown in the welding process and a strong decrease
in the drop transfer frequency. By changing the value of this function, each user can choose
the optimal welding process for themselves. In general, the minimum values are used for
welding thickness of more than 3 mm, and the maximum values are used for thinner
products.
By default, the inductance is set to OFF, i.e. set to zero stage. See paragraph 6.1 to change
the value of any function in the current welding mode.
5.4 BEGINNING OF WELDING VOLTAGE BUILD-UP FUNCTION
This function is necessary to smoothly reach the welding mode in the set time [t.uP], which
reduces splashing of the weld pool and splatter at the moment of striking, when the wire is
still cold. The extended smooth reach time is used for the initial weld pool formation. The
voltage build-up time [t.up] is responsible for regulating the smoothness of this process,
both in the source and in the wire feed speed control unit. For maximum correct operation,
these values must be consistent (not every feed unit has the ability to change the wire feed
speed at the end of welding).
CAUTION! The longer the build-up time, the smaller the initial weld, so it is used
only for medium and long seams. For this reason, do not increase the time by more than 0.1
seconds when welding with tacks, etc.
By default, the reach time is set to OFF, i.e. disabled. See paragraph 6.1 to change the value
of any function in the current welding mode.
CAUTION! When welding with steel wire, the build-up time [t.uP] at the source
must be either equal to or slightly less than that at the wire feeder. When welding with
aluminium wire, the build-up time [t.uP] at the source must be longer (+0.2...+ 0.5 sec) than
that at the wire feeder.
5.5 END OF WELDING VOLTAGE REDUCTION FUNCTION
This function is designed for smooth welding of the crater formed in the weld pool
under the influence of electromagnetic blast with an electric arc and subsequently being a
source of welding seam defects. The signal to start the function is to release the button on
the torch at the end of the welding process, and the movement of the torch must be stopped
