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.

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.

MULTIPROCESS SWITCH (K804-1)

Field installed kit that mounts on the front of the DC- 400, and includes hinged covers over its output studs. The switch has three positions: Positive semiautomat- ic / automatic, negative semiautomatic / automatic, and stick / air carbon arc. Required when using the DC-400 for both semiautomatic/automatic and stick / air carbon arc. The field installed kit is equivalent to the factory installed option. For details on the Multiprocess Switch, see the section for Installation of Equipment Required for Recommended Processes.

HI-FREQUENCY KIT

(K799 CODES 8634 AND AbOVE ONLY)

Kit supplies the high frequency plus gas valve for DC TIG welding. The DC-400 is shipped with proper R.F. bypass circuitry installed to protect the control circuit when welding with a HI-FREQ unit. K844 Water Valve Option Kit can be used with K799 when TIG welding with water cooled torches.
