Wire Feed Speed Adjust Knob
Use this knob to adjust the desired wire feed speed setting [50 to 780 ipm 1.3 to 19.8 mpm)]. Rotating the knob clockwise increases wire feed speed and
counter-clockwise decreases wire feed speed. Wire feed speed adjustment is active when the swoosh above the knob is illuminated. The setting can
be different for left and right sides and MIG process type, and the unit will hold these settings for both sides.
7.
Memory Card Indicator
The CARD text will illuminate to indicate that custom MIG type weld process data is currently being used from the memory card.
8.
MIG Process Type Indicator
The FCAW, MIG, RMD, or PULSE text illuminates to indicate which type of MIG process is selected at the welding power source (see Section 6-2). No
text illuminates when other welding processes are selected.

Jog Button
Press and hold this button to jog wire on either the left or right side depending on the active side selection. Rotate the wire feed speed adjustment knob to
change jog speed. Rotating the knob clockwise increases jog speed and counter-clockwise decreases jog speed. Release the button to stop the jog
operation and the display will return to the initial wire feed speed setting.
Wire jog is also initiated by pressing and holding the MIG gun trigger without establishing an arc. If the gun trigger is depressed and an arc is not estab-
lished, the feeder will automatically go into jog after 2 seconds.
Auto Jog
S
Pressing and releasing the jog and trigger hold buttons simultaneously will activate the auto jog function. Depending on the active side selection,
the left or right (dual feeder only) side will automatically jog a preset amount of wire. The volts/arc length display will count down in 0.1 ft or 0.01 m
decrements starting at the preset wire length. A default preset wire length is set at 15.3 ft (4.7 m), but the length can be changed within a range of
5.0 to 30.0 ft (1.5 to 9.1 m) using the volts/arc length adjust knob. Rotating the knob clockwise increases wire length and counter-clockwise
decreases wire length. The volts/arc length display will show the set wire length for a short time after making any desired adjustment. If no
further changes are made to the wire length after one second the unit will resume the count down display. Jog speed can also be adjusted within
a range of 50 to 780 ipm (1.3 to 19.8 mpm) using the wire feed speed adjust knob and the wire feed speed display will show the current jog speed
setting.

Trigger Hold Select Button
Press and release this button to enable/disable the trigger hold feature. The text above or below the button, either ON or OFF respectively, illuminates to
indicate the current trigger hold selection. When trigger hold is active, the gun trigger must be pressed and held for a minimum of one half second, but not
more than six seconds. Then releasing the gun trigger activates the trigger hold function. To stop welding, press the gun trigger for a minimum of one half
second, but not more than six seconds and release.
11.
Purge Button
Press and hold this button to purge shielding gas lines prior to welding and to preset gas pressure at the regulator for either the left or right (dual feeder
only) side. This button will also purge the TIG gas solenoid located at the welding power source if the TIG welding process is selected. Release the
button to stop the purge operation.
Timed Purge
S
Pressing and releasing the purge and trigger hold buttons simultaneously will activate the timed purge function. The volts/arc length display will
count down in 1 second decrements starting at the preset amount of time. A default preset time period is set at 30 seconds, but the time can be
changed within a range of 5 to 60 seconds using the volts/arc length adjust knob. Rotating the knob clockwise increases time and
counter-clockwise decreases time. The volts/arc length display will show the set time after making any desired adjustment. If no further
changes are made to the time period after one second the unit will resume the count down display.

Memory Select Button And Location Indicator
Press and release this button to scroll through stored unit configuration in locations 1-4. This button can only recall configurations and cannot be used to
restore factory default settings to a memory location (see Section 6-2).The numeral next to the button illuminates to indicate the active memory location.
