REMOTE SENSE LEAD SPECIFICATIONS

Genuine Lincoln Electric control cables should be used at all times
(except where noted otherwise). Lincoln Electric cables are
the Flextec 350XP CCC. 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 accel-
eration (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
control cables.
Paralleling Machines
The Flextec 350XP CCC power sources may be paralleled for
increased output requirements in constant current application. No
kit is required for paralleling of Flextec 350XP CCC power sources.
The Flextec 350XP CCC can only be paralleled for constant
current processes. Connect the power sources as shown, and set
the output control of each power sources to one half of the desired
arc current.
