Mounting the DH-10 Control Box (K1496-1,-2)
The same control box is used for both a DH double
header drive, or up to two single head drives. The back
plate of the control box has two keyhole slots and one
bottom slot for mounting. See Figure A.2 for the size
and location of these slots. Mount the box at some con-
venient location close to the wire drive unit which will
enable the desired control cable to reach between the
control box and the wire drive unit.
a) Drill the required holes in the mounting surface,
partially install 1/4-20 screws.
b) Mount the box.
c) Tighten the screws.

Connecting Wire Drive Unit to Control Box
One head to control cable assembly is required for each
head being used; however, only one electrode cable is
required if an electrode cable jumper (provided) is con-
nected between the two heads. The Head to Control
cable assemblies are available in two types:
K1785-"L" -Includes a control cable with 14-pin Ms-style
connectors on each end, and a 3/0 weld
cable (rated 600 amps, 60% duty cycle) to
route between the wire drive and the control
box. Available in lengths of 12 ft. (3.6m), 16
ft. (4.9 m) and 25 ft. (7.6 m).
a) 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.

b) Connect the 14-socket cable connectors to the mating
receptacles on the back of the wire feed unit connec-
tion box. Feeder Head 1 uses the left receptacle and
Feeder Head 2 uses the right receptacle, when facing
the front of the wire drive.
c) At the same end, connect the electrode lead to the
1/2" connection bolt on the front of the left wire drive
head feed plate. If only one electrode cable is being
used, comparable size electrode cable jumper (pro-
vided) must be connected between the two heads.
d) At the control box end, connect the 14 pin connectors
of the cables to the mating receptacles on the bottom
of the control box. Feeder Head 1 should be connect-
ed to the left receptacle and Feeder Head 2 should be
connected to the right receptacle, when facing the
front of the control box.
e) At the control box current sensor, slip the cover box
up off the sensor and connect the electrode cable(s)
to the top bolt connection.
Make weld lead connections from welder to feeder
reed switch box. (if not, poor starting or welding will
occur)
