CONTROL CABLE CONNECTIONS
GENERAL GUIDELINES
Genuine Lincoln control cables should be used at all
times (except where noted otherwise). Lincoln cables
are specifically designed for the communication and
power needs of the Power Wave ® / Power Feed ™ sys-
tems. Most are designed to be connected end-to-end
for ease of extension. Generally, it is recommended
that the total length not exceed 100ft. (30.5m). The
use of non-standard cables, especially in lengths
greater than 25 feet, can lead to communication prob-
lems (system shutdowns), poor motor acceleration
(poor arc starting) and low wire driving force (wire
feeding problems). Always use the shortest length of
control cable possible and DO NOT coil excess
cable.
Regarding cable placement, best results will be
obtained when control cables are routed separate
from the weld cables. This minimizes the possibility of
interference between the high currents flowing
through the weld cables and the low level signals in
the control cables. These recommendations apply to
all communication cables including ArcLink
® and
Ethernet connections.
COMMON EQUIPMENT CONNECTIONS
Connection Between Power Source and ArcLink ®
Compatible Wire Feeders
The K1543-xx 5-pin ArcLink
® control cable or the
heavy duty K2683-xx ArcLink ® control cable connects
the power source to the wire feeder. The control cable
consists of two power leads, one twisted pair for digi-
tal communication, and one lead for voltage sensing.
The 5-pin ArcLink
® connection on the Power Wave ®
S700 is located on the rear panel.
The control cable is keyed and polarized to prevent
improper connection. Best results will be obtained
when control cables are routed separate from the
weld cables, especially in long distance applications.
The recommended combined length of the ArcLink
®
control cable network should not exceed 200ft.
Connection Between the Power Source and
Optional DeviceNet Programmable Logic
Controller (PLC)
It is sometimes more practical and cost effective to
use a custom PLC interface to control a system. The
Power Wave
® S700 is equipped with a 5-pin
DeviceNet mini-style receptacle for this purpose. The
receptacle is located on the rear panel of the machine.
The DeviceNet cable is keyed and polarized to pre-
vent improper connection.
Note: DeviceNet cables should not be routed with
weld cables, wire drive control cables, or any other
current carrying device that can create a fluctuating
magnetic field.
DeviceNet cables must be sourced locally by the cus-
tomer. For additional guidelines refer to the
“DeviceNet Cable Planning and Installation Manual”
(Allen Bradley publication DN-6.7.2).
Connection Between Power Source and Ethernet
Networks
The Power Wave
® S700 is equipped with a RJ-45
Ethernet connector, which is located on the rear
panel. All external Ethernet equipment (cables,
switches, etc.), as defined by the connection dia-
grams, must be supplied by the customer. It is critical
that all Ethernet cables external to either a conduit or
an enclosure are solid conductor, shielded cat 5e
cable, with a drain. The drain should be grounded at
the source of transmission. For best results, route
Ethernet cables away from weld cables, wire drive
control cables, or any other current carrying device
that can create a fluctuating magnetic field. For addi-
tional guidelines refer to ISO/IEC 11801. Failure to fol-
low these recommendations can result in an Ethernet
connection failure during welding.
Connections Between Power Sources in Multi-Arc
Applications
The Power Wave
® S700 is equipped with an I/O con-
nector such that two power sources can be used for a
Synchronized Tandem application. An Autodrive 19
Tandem controller is required for tandem welding.
Refer to Connection Diagrams for more information on
the Synchronized Tandem configuration.
