5.9.13.2 KHz pulses (metallurgic pulses)
The kHz pulses (metallurgic pulses) use the plasma pressure produced at high currents (arc pressure)
which is used to achieve a constricted arc with concentrated heat feeding. The frequency can be infinitely
adjusted from 50 Hz to 15 kHz and the pulse balance from 1-99 %.
In contrast to thermal pulses, the pulse edge times are not required.
The pulse process continues during the up-slope and down-slope phases!
Select kHz pulses
Press the "TIG pulses" button until the
signal light lights up in red
Select balance
Setting range: 1% to 99% (1% increments)
Select frequency
Setting range: 50 Hz to 15 kHz
5.9.13.3 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.
