• FREQUENCY
• BALANCE
NOTE: AC function only
FREQUENCY:
Normal AC frequency
from the wall outlet is 60
Hz, which is the number
of times the current
alternates between DCEN
and DCEP in one second.
A higher frequency (90-
240 Hz) focuses the arc.
A lower frequency (40-
90 Hz) softens the arc.
BALANCE:
Normal AC frequency
spends 50% of the time
in DCEN and 50% of the
time in DCEP. Adjusting
the Balance determines
how long the polarity
stays in DCEN. A higher
percentage of DCEN (60-
80%) creates a tighter
arc, less cleaning, and
reduces tungsten balling.
A lower percentage of
DCEN (40-60%) creates
a less-focused arc, more
cleaning, and will likely
create a ball on the top of
the tungsten.
