REMOTE CONTROL ADAPTER CABLE (K864)
A “V” cable 12” (.30m) long to connect a K857
Remote Control, K963 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 then not used.
ELECTRIC SHOCK can kill.

power source “OFF” before installing
plugs on cables or when connecting
or disconnecting plugs to welding

AMPTROL™ ADAPTER CABLE (K843)
A five wire cable, 12” (.30m) long, is available for easy
connection of standard K963 Hand Amptrol or K870
Foot Amptrol. The cable has a 6-pin MS-style con-
nector which connects to the Amptrol and terminals
which connect to 75, 76 and 77 on the machine termi-
nal 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
nonfunctional unless used with a K799 Hi-Frequency
Kit.
