8 Percentage Of Weld Output
Inductance
Use Arc Length control knob to se-
lect the percentage of welding in-
ductance value. When selected,
use the knob or sequencer P3 push
buttons to change value. Default =
0% (min = −10%, max = +10%).
Low inductance is used for most
short arc applications, High induct-
ance is for stainless steel and spray
arc applications.
.
In short circuit GMAW welding,
an increase in inductance will
decrease the number of short
circuit transfers per second
(provided no other changes are
made) and increase the arc-on
time. The increased arc-on
time makes the welding puddle
more fluid.
9 Postflow Time
Use Arc Length control knob to set
length of time gas flows after weld-
ing stops to protect the weld puddle.
When this item is selected, use the
Wire Feed Speed adjustment knob
to change value. Default = 0.3
seconds (min = 0 sec, max = 3 sec).
