Use Encoder 9 for fine adjustment of the
Positive/Negative Balance from 10% - 90%.
Percentage of Balance shown refers to the
Negative 'melting effect' of the arc. Below an
example of 2 extreme conditions.
Case A: Maximum cleaning, minimum penetration,
Tungsten burn-back.
Case B: Maximum penetration, minimum cleaning,
limited Tungsten electrode wear out.
After many years of experience and study an
optimum compromise is estimated with a balance
of 80% and 80Hz of Frequency.
