amperage the base amperage will adjust to pulse amps %.

Pulse frequency adjustment
This can be adjusted as follows:
DC Mode 0.1 to 500Hz
AC Advanced Squarewave 0.1 - 250Hz
AC Soft Square, Triangular and Sinewave 0.1 - 10Hz
Advanced AC Pulse 0.1 - 10Hz

AC Frequency
Transformer based welders are normally fixed at 60Hz, due to the advanced inverter
technology you can adjust from 20 - 250Hz.
The higher the AC frequency the narrower the arc becomes allowing you to have a more
precise weld bead and penetration. This can also quicken up travel speed and ideal for
production welding.
You will hear the pitch of the weld noise get higher, this is normal.
Welding at lower frequency will give reduced control of arc and a wider weld pool.
11.
AC Balance
This sets the % of electrode positive used during AC welding to provide a cleaning action
as alloys have a oxide layer that has a higher melting temperature than the base metal and
this needs to be lifted off.
So you can control the amount of cleaning or penetration.
Too much cleaning will cause the tungsten to wobble and split, Too little cleaning can result
in a dirty dull weld.
So as you increase the % the more cleaning will happen however less penetration will be
achieved.
For most situations a setting of 30 - 40% will give you a good clean weld finish, If you go
above 50% you will find the tungsten will overheat and the end can fall of into weld pool.
If you find you are getting tungsten wobble using 30-40% balance then you may need to go
up a tungsten size.
12.
Down-Slope
Adjustable from 0 - 25 seconds, This allows you to gradually decrease the amperage from
main amps to end/final amps when using torch trigger operation.
When using foot pedal ensure down-slope is set to 0
13.
End Amperage
This allows you to set the end current from 5A DC and 10A AC. In 4T mode when trigger is
pressed and held the second time you will remain at end amps, when you let go machine
will then stop welding.
