INSTALLATION OF FIELD INSTALLED
OPTIONS
Remote Output Control (K857 or K857-1
with K864 Adapter)
An optional “remote out control” is available. The
K857 or K857-1 are the same remote control options
that are used on other Lincoln power sources. The
K857 or K857-1 consist of a control box with 25 feet
(7.6 meters) or 100 feet (30.3 meters).
The K857 and K857-1 have a 6-pin connector and
K857 require a K864 adapter cable which connects to
the 14-pin connector on the case front.
REMOTE CONTROL ADAPTER CABLE (K864)
A “V” cable 12” (.30m) long to connect a K857
Remote Control (6 pin connector) with a wire-feeder
(14-pin connector) and the machine (14-pin connec-
tor). If a remote control is used alone the wire-feeder
connection is then not used.
AMPTROL ADAPTER CABLE (843)
A five wire cable, 12” (.30m ) long, used for easy
connection of standard K963 Hand Amptrol or K870
Foot amptrol. The cable has a 6-pin MS-style
connector which connects to the Amptrol and termi-
nals which connect to 75, 76, and 77 on the machine
terminal strip and to the case grounding screw. the
Amptrol will control the same range of output as the
current control on the welder. (if a smaller range of
control is desired for finer adjustment, a K775 Remote
may be used in conjunction with the Amptrol Adapter
Cable Kit.) The Amptrol arc start switch is nonfunc-
tional unless used with a K799 Hi-Frequency Kit.
See Amptrol Adapter installation Instructions on next
page.
ELECTRIC SHOCK can kill.
• Turn the power switch of the
welding power source “OFF”
before installing plugs on
cables or when connecting or
disconnecting plugs to weld-
ing power source.
