TIG AC/DC
Welding in AC/DC is possible to adjust the
Frequency AC da 20 a 200 Hz with the Encoder
8
Also it's possible to adjust the Balance from
positive and negative from 10% to 90% with the
Encoder
9; here below we show the 2 extreme
conditions.
Case A : Maximum penetration, minimum cleaning,
limited Tungsten electrode wear out.
Case
B : Maximum cleaning, minimum penetration,
Tungsten electrode wear out.
After many years of experience and study the best
compromise normally is with a balance of 80% and
80Hz of Frequency.
