Pulse variants

This parameter setting is specified by the robot control via the RINT X12 or BUSINT X11 robot
interface (see documentation in the relevant interface description).
The machines have an integrated pulse device.
With pulses, the machine switches back and forth between the pulse current (main current) and
pause current (secondary current).

5.17.1 Pulses (thermal pulses)

5.17.2 KHz pulses (metallurgic pulses)

The kHz pulses (metallurgic pulses) use the plasma pressure produced at high currents (arc pressure)
which is used to achieve a constricted arc with concentrated heat feeding.
The pulse process continues during the up-slope and down-slope phases!

5.17.3 Automated pulses

The automated pulses are used with tacking and spot welding of workpieces in particular.
An oscillation in the molten pool is produced by the current-dependent pulse frequency and balance,
which positively influences the ability to bridge the air gap. The pulse parameters required are
automatically specified by the machine control.
