5.2.20 Pulse welding
The following pulse types can be selected:
•
Automated pulsing
•
Thermal pulsing
•
Metallurgical pulsing
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).
5.2.20.1 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.

5.2.20.2 Thermal pulsing
The operation sequences basically match the standard welding sequences, but there is an additional
switching back and forth between the main current AMP (pulse current) and the secondary current AMP%
(pulse pause current) at the set times. Pulse and pause times and the pulse edges (
entered in seconds on the control.
