CABLE CONNECTIONS
There are three circular connectors on the front of the
POWER FEED® 25M.
There is one circular connector on the rear of the POWER FEED® 25M.
DIGITAL CONTROL CABLE, K1543-XX
(See Figure A.3)
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 elec-
trode sense lead.
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 con-
trol cable between components.
