INSTALLATION OF THE SYNERGIC 7F COMPONENTS

Safety Precautions

Mounting the Wire Feed Unit (K679-1 or -2)

Mount the wire feed unit by means of the insulated
mounting bracket attached to the bottom of the gear-
box. Reference L9777 dimension print at the rear of
this manual to find the size and location of the mount-
ing holes. The gearbox assembly is electrically “hot”
when the gun trigger is pressed. Therefore, make cer-
tain the gearbox does not come in contact with the
structure on which the unit is mounted.

The wire feed unit should be mounted so that the
drive rolls are in a vertical plane so dirt will not collect
in the drive roll area. Position the mechanism so it will
point down at about a 45° angle so the wire feed gun
cable will not be bent sharply as it comes from the
unit.

Mounting the Control Box (K678-2)

The same control box is used for both the Synergic 7F
and Synergic 7FH wire feed units and contains two
keyhole slots and one slot for mounting. Reference
M17740 dimension print in the rear of this manual for
size and location of these slots. Mount the box at
some convenient location close to the wire feed unit
which will enable the desired control cable assembly
to reach between the control box and the wire feed
unit.

a) Drill the required holes in the mounting surface,

partially install 1/4-20 screws.

b) Open the control box door by removing the two

door screws.

c) Mount the box.
d) Tighten the screws.
e) Close the control box door and replace the door

screws.

Connecting Wire Feed Unit to Control Box

The Feeder to Control cable assemblies are available
in two types:

K680-”L” Includes a control cable with 14-pin MS-

style connectors on each end, and a 4/0
weld cable to route between the Wire
Drive and the Control Box. Available in
lengths “L” of 16ft. (4.9m) and 25ft.
(7.6m).

K681-”L” Same as K680, but does not include

weld cable. Available in lengths “L” of
12ft. (3.6m), 16ft. (4.9m) and 25ft.
(7.6m).

1. Making certain the cables are protected from any

sharp corners which may damage their jackets,
mount the cable assembly along the boom so the
end with the female MS-style connector pins is at
the wire feed unit.

2. Connect the 14-socket cable connector to the

receptacle on the back of the wire feed unit con-
nection box.

3. At the same end, connect the electrode lead to the

connection stud of the brass gun connection block
on the front of the wire feed unit.

4. At the control box end, connect the 14-pin connec-

tor of the cable to the mating receptacle on the
bottom of the control box.

Electrode Routing

The electrode supply may be either from reels, Readi-
Reels, spools or bulk packaged drums or reels.
Observe the following precautions:

1. The electrode must be routed to the wire feed unit

so that the bends in the wire are at a minimum,
and also that the force required to pull the wire
from the reel into the wire feed unit is kept at a
minimum.

2. The electrode is “hot” when the gun is energized

and must be insulated from the boom and struc-
ture.

3. If more than one wire feed unit shares the same

boom, their wire and reels must be insulated from
each other and insulated from their mounting
structure.

WARNING

Observe all additional Safety Guidelines detailed
throughout this manual.

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts such

as output terminals or internal wiring.

• When inching with gun trigger, electrode and

drive mechanism are “hot” to work and
ground and could remain energized several
seconds after the gun trigger is released.

• Turn OFF input power at welding power
