CABLE CONNECTIONS

There are three circular connectors on the front of the

POWER FEED™ 25M.

(See 5-pin, 6-pin and 7-pin- Figure A.1)

There is one circular connector on the rear of the POWER

FEED™ 25M. Maximum control cable length is 200 ft (61 m).

ARCLINK CONTROL CABLES

(See Figure A.3)

ArcLink Control Cables are available in two forms:

• K1543-xx series for most indoor or factory installa-

tions.

• K2683-xx series for outdoor use or when the equip-

ment is frequently moved.

ArcLink/LincNet control cables are special high quality

cables for digital communication. The cables are cop-

per 5 conductor cable in a SO-type rubber jacket.

There is one 20 gauge twisted pair for network com-

munications. This pair has an impedance of approxi-

mately 120 ohms and a propagation delay per foot of

less than 2.1 nanoseconds. There are two 12 gauge

conductors that are used to supply 40VDC to the net-

work. The fifth wire is 18 gauge and is used as an

electrode sense lead.

FIGURE A.1

FIGURE A.2

Use of non-standard cables may lead to system shut-

downs, poor arc starting and wire feeding problems.

The control cables connect the power source to the

wire feeder, and the wire feeder to other wire feeders.

Control cables may be connected end to end to

extend their length. Use a maximum of 200 ft.

(61.0m) of control cable between components.
