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 connec-
tor which connects to the Amptrol and terminals 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 is nonfunctional in this application.
