Trim
Description
Pulse welding controls the arc
length with 'Trim' instead of volt-
age. When trim (arc length) is
adjusted, the Power Wave auto-
matically recalculates the voltage,
current and time of each part of
the pulse waveform for the best
result. Trim adjusts the arc length and ranges from 0.50 to 1.50. Increasing the trim
value increases the arc length, while decreasing the trim value decreases the arc
length.
