AMPTROL ADAPTER FOR K799 HI-FREQUENCY KIT (K915-1, REQUIRES K864 ADAPTER)

A “V” cable to connect a K799 Hi-Freq Kit (5-pin con- nector) with either a K963 Hand Amptrol or a K870 Foot Amptrol (6-pin connector) and the machine. The cable going to the machine has a 6-pin connector which requires a K864 adapter to connect with the 14- pin connector on the DC-400. Refer to S20909 instructions for connection information.

MULTIPROCESS SWITCH (K804-1)

Kit that mounts on the front of the DC-400, and includes hinged covers over its output studs. The switch has three positions: Positive semiautomatic/automatic, negative semiautomatic/ automatic, and stick/air carbon arc. Required when using the DC-400 for both semiautomatic/automatic and stick/air carbon arc.

Install per M17137 instructions included with the field installed kit.

CAPACITOR DISCHARGE CIRCUIT (K828-1)

Circuit that mounts inside the DC-400.

Recommended when:

1)DC-400 is used in conjunction with any LN-23P or older LN-8 or LN-9 semiautomatic wire-feeder. Eliminates possible arc flash re-start of weld when trigger interlock is used. Not required with current LN-8 (above Code 8700), or LN-9’s with serial num- bers above 115187 (manufactured after 12/83), or any LN-9 having an L6043-1 Power PC Board.

2)DC-400 is used with an LN-22 equipped with an older K279 Contactor-Voltage Control Option. Eliminates electrode overrun when gun trigger is released. Not required when later K279 (above Code 8800) is used.

3)DC-400 is used with any semiautomatic wire-feeder and possible small spark, if electrode touches work just after gun trigger is released, is objectionable. Install per M17060 instructions included with the Kit.

UNDERCARRIAGES (K817, K817R, K841)

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.

OPTIONAL EQUIPMENT

Factory Installed Options

DIODE OPTION

This internally installed option allows the use of the cold start and cold electrode sensing features of the NA-3, NA-5 or NA-5R.

MULTIPROCESS SWITCH

Factory or field installed kit that mounts on the front of the DC-400, and includes hinged covers over its out- put studs. The switch has three positions: Positive semiautomatic / 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 equiva- lent is identified as K804-1. For details on the Multiprocess Switch, see the Installation of Equipment section.

Field Installed Options

REMOTE OUTPUT CONTROL

(K857 WITH K864 ADAPTER 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 so marked with the symbol on the machine. These terminals are located behind the control panel on the front of the power source. This control will give the same control as the output control on the machine.
