5.1.7.4  Metallurgical pulsing (kHz pulsing) 

Metallurgical pulsing (kHz pulsing) uses the plasma force (arc force) occurring at high currents which al-

lows you to achieve a constricted arc with concentrated heat input. Unlike thermal pulsing, no times are 

set; a frequency 

 and the balance 

 are set instead. The pulsing process also occurs during the up-

slope and down-slope phase.
