Setting Crater Fill - Miller Millermatic 350P Technical Manual

6-6. Setting Crater Fill

.
Crater parameters are welding gun independent (i.e. crater fill can be on for a spool gun and off
for a MIG gun). When using the same welding gun, MIG and pulse programs are independent
of each other; however, crater parameters will be the same for all pulse programs. For example,
if a MIG gun is using the .035 steel pulse program, and crater fill is on and parameters are set,
crater will also be on and the same parameters will be set for a stainless pulse program.

either volts (range is 10.0-32.0 volts) or arc
length [range is 0-99 (see Section 6-7)].

Rotate left knob (2) to change display to
TDLY for time delay. This setting is for spot
or skip welding without crater fill if the arc
time is less than the set time. Time range is
0.0-5.0 seconds (i.e. if TDLY is set for 2.0
seconds, weld operation will not go into
crater if gun trigger is released before 2.0
ARCL
seconds).
