8) Back out the screws for the incoming and outgoing
guide tubes.
9) Install the longer guide tube in the rear hole near
the incoming drive roll. Slide the tube in until it
almost touches the roll. Tighten in place.
10) Install the remaining guide tube in the front hole.
Be certain that the proper plastic insert is used.
Fine wire chisel point tube must have largest
radius next to drive roll. Tighten in place.
11) Re-latch both quick release levers.
12) To start new electrode, straighten the first 6"
(150mm) and cut off the first 1" (25 mm). Insert
free end through the incoming tube. Press gun
trigger and push wire into the drive roll.

Gun and Cable Assemblies
GMAW Guns
An expanding line of Magnum gun and cable assem-
blies are available to allow welding with solid and
cored electrodes using the GMAW process. See the
appropriate Magnum literature for descriptions of the
200 to 550 ampere air cooled gun and cables that are
available. Gun cable lengths range from 10 ft. (3.0 m)
to 25 ft. (7.6 m) and feed electrode sizes .025" (0.6
mm) to 5/64" (2.0 mm). The entire line of Magnum
Fast-Mate gun and cable assemblies can also be
used by installing a K489-1 Fast-Mate adapter kit.
Innershield Guns
K126 and K115 gun and cable assemblies are
available to allow welding with Innershield elec-
trodes. Gun cable lengths range from 10 ft. (3.0
m) to 15 ft. (4.5 m). The 350 ampere K126 with
Synergic 7 will feed electrode sizes .062" (1.6 mm)
to 5/64" (2.0 mm). The 450 ampere K115 with
Synergic 7 will feed 5/64" (2.0 mm) electrode.
Three smoke extraction gun and cable assemblies
are available, 250 ampere K309, 350 ampere K206
and the 500 ampere K289. All gun cable lengths
are 15 ft. (4.5 m). Both the K206 and K309 with
Synergic 7 will feed electrode sizes .062" (1.6 mm)
to 5/64" (2.0 mm). K289 with Synergic 7 will feed
5/64" (2.0 mm) electrode. These guns require the
use of the K184 vacuum unit for use with Synergic
7.
INSTALLATION
Gun Cable Connection: Wire Feeder to Gun
Lay the cable out straight. Insert the connector on the
welding conductor cable through the large hole in the
front panel of the Synergic 7 and into the brass con-
ductor block on the front of the gearbox. Make sure it
is all the way in and tighten the hand wheel. Keep this
connection clean and bright. Connect the control
cable polarized plug into the mating 5 cavity recepta-
cle on the front of the control section below the key-
pad.
For GMA Gun Cables:
Install the barbed fitting and union nut to the 5/8-18
female inert gas fitting on the front of the Synergic 7
wire drive. Connect the 3/16" I.D. gas hose from the
gun cable to the barbed fitting. When the gun is to be
removed, this fitting can be easily detached by loosen-
ing the union nut.
