When pulse welding you have the main (peak) and base (background) amperage. By adjusting the pulse
time % you determine which one will be more prominent, the pulse or base. At a low % the base current
will be on longer so you will reduce heat input. At a high % the peak current will be on longer so you
This adjusts how often the pulse will happen per second, at 0.5Hz it will be a very slow pulse and you will
be able to see the change, when welding at high frequency the sound of arc will change to a higher pitch
This sets the % of pulse vs base amps. I.E If main amperage (peak) is set to 120amps and you set at 50%,
the base amps will be 60amps. Generally a setting of 35-75% base amps suits most jobs.
