NOTE
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).
Pulses (thermal pulses)
With thermal pulses, the pulse and pause times (frequency up to 200 Hz) and the pulse edges (ts1 and
ts2) are entered in seconds on the control.
