Automated pulses
The automated pulsing pulse variant is only activated for DC welding in combination with the spotArc ope-

have a positive effect on the gap bridging. The required pulse parameters are automatically defined by
the machine control. If required, the function can be disabled by pressing the pulsed welding push-button.

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 (
