Lincoln Electric IM10096 POWER MIG 256 - Manual (Page 22)

C-2 C-2
Closing either gun trigger will cause the electrode
of both guns to be electrically "HOT". Be sure
unused gun is positioned so electrode or tip will
not contact metal case or other metal common to
work.
------------------------------------------------------------------------
1. Pulling the trigger for the built-in feeder gun:
• Disables spool gun operation.
• Closing feeder gun trigger starts feeder gun
welding and makes both electrodes electrically
"HOT".
2. Pulling SPOOL GUN Trigger:
• Disables built-in feeder gun operation.
• Closing spool gun trigger starts spool gun weld-
ing and makes both electrodes electrically
"HOT".
3. Operation with POWER MIG ® 256:
• Turn the POWER MIG ® 256 input power ON.
• Adjusting the voltage control will increase or
decrease your welding voltage.
• Adjusting the wire speed control on the spool
gun will increase or decrease the spool gun wire
feed speed.
• To aid in set-up, the POWER MIG ® 256 wire feed
speed(WFS) meter will display the approximate
WFS of the gun. Actual WFS at the gun may vary
from the displayed value due to tension setting,
liner condition or gun variation.
CONNECTING THE SPOOL GUN TO
THE POWER MIG
® 256
(See Figure C.1)
1. Connect the Spool Gun control cable to the mating
7-pin receptacle in the Power MIG wire drive
compartment. K487-25 Magnum SG Spool Gun
requires K2445-1 cable 7-pin to 6-pin adapter.
2. Connect the Spool Gun electrode lead to the
(+)positive stud with the Spool Gun electrode lead
sandwiched between the (+)positive power source
electrode lead and the (+)positive stud. Tighten and
be careful not to strip the threads.
3. Attach the Spool Gun gas line to the 5/8 Gas fitting
on the front of the machine.
4. Attach a Gas hose from the Gas supply to the rear
inlet gas fitting marked “Spool” on the POWER MIG ®
256.
MAKING A WELD WITH THE SPOOL
GUN
The POWER MIG ® 256 control circuitry is designed to
sense either the spool gun or (built in) wire feeder
trigger circuitry. The spool gun can easily be plugged
in and will be ready to use.
