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 on the machine. These 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.

K843 AMPTROL™ ADAPTER INSTALLATION INSTRUCTIONS

WARNING

ELECTRIC SHOCK can kill.

•Turn the input supply power OFF before installing plugs or cables or when connecting or disconnecting plugs to the welder.

This K843 adapter is used to connect Amptrol (K812, K813 or K870), remote control (K775), and Hi-Freq™ (K799) accessories to the DC-400. The OUTPUT CONTROL switch must be in “Remote” for Amptrol™ to control current. Accessories may be combined and connected in four different ways, as shown on the fol- lowing page.
