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 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.

REMOTE CONTROL ADAPTER CAbLE (K864)

For easy moving of the machine, optional undercar- riages are available with either steel (K817) or rubber tired (K817R) wheels or a platform undercarriage (K841) with mountings for two gas cylinder at rear of welder.

Install per instructions provided with trailer.

The switch has three positions: Positive semiautomat- ic / automatic, negative semiautomatic / automatic, and stick / air carbon arc.
