Control Cable Connections, Paralleling - Lincoln Electric RED-D-ARC FX650XL Operator's Manual

FX650XL
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 FX650XL. Most are
designed to be connected end to end for ease of extension.
Generally, it is recommended that the total length not exceed 100
feet (30.5 m). The use of non-standard cables, especially in
lengths greater than 25 feet, can lead to communication problems
(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.
PARALLELING
FX650XL power sources may be paralleled for increased output
requirements without the need of any additional kits or equipment
(See Figure A.3). The FX650XL can be paralleled for constant
current processes (switch must be in the SMAW position; set the
output of each power source to one half of the desired current) or
when placed in Multi-Weld™* mode (switch must be in the Multi-
Weld™ position; voltage will be set at the Mult-Weld™).
