FUNCTION
PURPOSE
17. AC Balance
50‑98%
Defines the percent of Electrode Positive (EP) used during AC welding to
provide cleaning action. This divides the time that the AC cycle spends
in Electrode Positive or Electrode Negative during one full AC cycle. It
controls the amount of cleaning and penetration via a ratio to achieve
the best balance while welding on AC. Too much cleaning action will
result in tungsten balling or splitting. Too little cleaning can result in
dirty, sooty welds and even a dull weld appearance. Simply put, as the
percent increases, greater cleaning will occur, but less penetration will
be achieved. For old aluminium that has some corrosion, adjust the ac
balance to where you use more (EP).
18. AC Frequency 10‑200 Hz Governs the number of times per second that the current alternates in
AC mode. To achieve greater arc focus (constriction) and increase puddle
agitation while welding in AC mode, increase AC frequency. This allows
pinpoint use on thin materials, and helps penetration on thicker materials.
Ideal adjustment range is usually between 80‑120Hertz. For comparison
most transformer welders operate on 60 Hz. Greater arc control and
stability can be achieved through the higher frequency range offered by
this welder. Lower Frequencies will widen and soften the arc and reduce
the level of control. WARNING: INCREASING THE AC FREQUENCY ALSO
INCREASES THE DECIBEL/NOISE LEVEL OF THE AC WELDING ARC. HEARING
PROTECTION SHOULD BE WORN!
