Failure to follow these instructions can cause immedi-
ate failure of components within the machine.
When powering welder from a generator be sure
to turn off the welder first, before generator is
shut down
in order to prevent damage to welder.
Output Cable Connections
The output leads are connected to the output termi-
nals marked “
+
” and “
-
”. They are located at the lower
right and lower left corners of the front panel. The
CV-400 provides 1/2” studs for weld cable connection.

Installation of 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.
The K775 consists of a control box with 28 ft (8.5m) of
four conductor 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.
REMOTE CONTROL ADAPTER CABLE (K864)
A “V” cable 12” (.30m) long to connect a K857
Remote Control (6 pin connector) with a wire-feeder
(14-pin connector) and the machine (14-pin connec-
tor). If a remote control or amptrol is used alone the
wire-feeder connection is then not used.
CAPACITOR DISCHARGE CIRCUIT (K828-1)
Circuit that mounts inside the CV-400.
Recommended when:
1) CV-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
numbers above 115187 (manufactured after
12/83), or any Ln-9 having an L6043-1 Power PC
Board.
2) CV-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) CV-400 is used with any semiautomatic wire-feed-
er and possible small spark, if electrode touches
work just after gun trigger is released, is objection-
able.
Install per M17060 instructions included with the
Kit.
ELECTRIC SHOCK can kill.
• Turn the power switch of the
welding power source “ OFF ”
before installing plugs on cables or
when connecting or disconnecting plugs to
welding power source.
