5.10.11.3 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.
