5-6. Setting Crater Fill
To set Crater Fill, select a program and
press SETUP (1) until the TIMERS LED
turns on. Press SETUP again and the left
display will show
CRTR
and the right display
will show
OFF
.
Rotate right knob (3) to turn crater
ON
.
Rotate left knob (2) to change display to
WFS
, and rotate right knob (3) to set crater
wire feed speed. Wire feed speed range is
50-700 IPM (see Section 5-7).
Rotate left knob (2) to change display to
TIME, and rotate right knob (3) to set crater
time. Time range is 0.1-5.0 seconds (see
Section 5-7).
Rotate left knob (2) to change display to
VOLT
(MIG program) or
ARCL
(pulse
program), and rotate right knob (3) to set
either volts (range is 10.0-32.0 volts) or arc
length [range is 0-99 (see Section 5-7)].
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
seconds).
To exit this menu, press the SETUP (1)

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 pro-
grams 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 pro-
gram, 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.
