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-9ʼs 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.
