CABLE INDUCTANCE AND ITS EFFECTS ON
WELDING
Excessive cable inductance will cause the welding performance to
degrade. There are several factors that contribute to the overall
inductance of the cabling system including cable size and loop
the electrode and work cables and the overall welding loop length.
electrode cable (A) + work cable (B) + work path (C) (See Figure
A.5).
FIGURE A.4
C
To minimize inductance always use the appropriate size cables,
and whenever possible, run the electrode and work cables in close
proximity to one another to minimize the loop area. Since the most
avoid excessive lengths and do not coil excess cable. For long
work piece lengths, a sliding ground should be considered to keep
the total welding loop length as short as possible.
Electrode Voltage Sensing
The remote electrode sense lead (67) is built into the 5-pin
ArcLink control cable and is always connected to the wire drive
feed plate when an ArcLink wire feeder is present. Enabling or
Voltage sense leads requirements are based on the weld process

CONTROL CABLE CONNECTIONS
General Guidelines
Genuine Lincoln control cables should be used at all times (except
for the communication and power needs of the engine driven
welder and Power Feed systems. Most are designed to be
®
connected end to end for ease of extension. Generally, it is
recommended that the total length not exceed 200 ft (61 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
control cables.
Connection Between Air Vantage
Compatible Wire Feeders
ArkLink
®
The 5-pin ArcLink ® control cable connects the Air Vantage
to the wire feeder. The control cable consists of two power leads,
one twisted pair for digital communication, and one lead for voltage
sensing. The 5-pin ArcLink ®
600X-I is located on control 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
exceed 200 ft (61 m).
CROSSLINC TECHNOLOGY
This machine features CrossLinc technology, which allows for
remote control of the welding output via the weld cables rather
than a control cable. As result, the control cable is no longer
needed when connected to a CrossLinc compatible wire feeder or
remote control.
This machine will function with all CrossLinc compatible wire
feeders except for the oldest LN-25X models. Incompatible models
include:
