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.
5.7 END OF WELDING VOLTAGE/FEED SPEED RAMP-DOWN 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
and a pit (which is essentially a crater) in the welding seam must be welded with a reducing
voltage. The smoothness of this process is regulated by the voltage ramp-down time [t.dn]
of the source, and the ramp-down time of the wire feed speed [t.dn] of the feed mechanism.
These values must match for correct operation. By default, the value is set to 0.1 sec, i.e., in
fact, in the OFF state. You can change this value at your own discretion. See point 6.1 for the
switching procedure.
CAUTION! When welding with steel wire, the reduction time [t.dn] at the source
must be either equal to or slightly more than that at the wire feeder. When welding with
aluminium wire, the reduction time [t.uP] at the source must be less (-0.3...-0.7 sec) than
that at the wire feeder.
5.8 PULSE VOLTAGE 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, so it primarily affects the
shape of the seam. There is also a forced effect on the transfer of a drop into the weld pool,
which in turn affects the stability of the process. As with other types of welding, this process
replaces the welder's hand movements to some extent, especially in hard-to-reach places. In
addition to the correct shape, the quality of seam formation also depends on the correct
setting, which reduces the likelihood of pores and reduces the grain structure, and thus
increasing the strength of the welded joint.
To implement this function in the source, you need to set three parameters:
pulsation power [Po.P], pulsation frequency [Fr.P] and pulse/pause ratio (or "duty cycle")
[dut]. By default, pulsation power [Po.P] as a key parameter is set to OFF, i.e., the function
is turned off, and pulsation frequency [Fr.P] and "duty cycle" [dut] at the values of 20 Hz and
50%, respectively. To enable the function, simply set the pulsation power [Po.P] above zero.
This parameter is set as a percentage of the used main welding voltage set.
