Automated pulses

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).
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.
