REMOTE OUTPUT CONTROL (K857 WITH K864
ADAPTER PLUG OR K775)
The K857 has a 6-pin MS-style connector. The K857
requires a K864 adapter cable which connects to the
14-pin connector on the machine.
An optional "remote output control" is available. This
is the same remote control that is used on the Lincoln
R3R and DC-600 power sources (K775). The K775
consists of a control box with 28 ft (8.5m) of four con-
ductor cable. This connects to terminals 75, 76, and
77 on the terminal strip and the case grounding screw
marked with the symbol
terminals are located behind the control panel on the
front. This device will give the same control as the out-
put control on the machine.

REMOTE CONTROL ADAPTER CABLE (K864)

A "V" cable 12 inches (.30 m) long to connect a K857
Remote Control, K812 Hand Amptrol or K870 Foot
Amptrol (6-pin connector) with a wire-feeder (14-pin
connector) and the machine (14-pin connector). If a
remote control or amptrol is used alone, the wire-feed-
er connection is not used. See Figure C.3.
AMPTROL™ ADAPTER CABLE (K843)
A five wire cable, 12 inches (.30 m) long, is available for
easy connection of standard K812 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. Connection information is included with the
Amptrol Adapter Cable Kit.) The Amptrol arc start
switch does not function in this application.
