OPTIONS/ACCESSORIES
The following options/accessories are available for your
CV-400 from your local Lincoln Electric Distributor.
FACTORY INSTALLED OPTIONS
Diode Option - This internally installed option allows
use of the cold start and cold electrode sensing fea-
tures of the NA-3, NA-5, or NA-5R automatic wire feed-
ers. See the topic
Connecting the NA-3 [NA-5] to the
CV-400
.
Ammeter and Voltmeter - Display output current and
voltage when welding.
FIELD INSTALLED OPTIONS
The following options/accessories are available from
your local Lincoln Distributor.
Undercarriage (K817P) - Includes a platform and
polyolefin wheels for easily moving the welder.
Undercarriage (K841) - Includes a platform, wheels,
and brackets for supporting the welder and two gas
cylinders.
Remote Output Control (K775 or K857 with K864
Adapter Plug) - The K857 has a 6-pin MS-style con-
nector. The K857 requires a K864 adapter cable which
connects to the 14-pin connector on the CV-400.
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 ground-
ing screw marked with the symbol on the machine.
These terminals are located behind the control panel
on the front. These devices will give the same control
as the output control on the machine.
Remote Control Adapter Cable (K864) - A "V" cable
12 inches (.30 m) long to connect a K857 Remote
Control with a wire-feeder control cable (14-pin con-
nector) and the machine (14-pin connector). If a remote
control is used alone, the wire-feeder connection is not
used. See Figure C.1.
Capacitor Discharge Circuit (K828-1) - Mounts inside
the CV-400. Recommended when:
• 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-9s with serial numbers
above 115187 (manufactured after 12/83), or any LN-
9 having an L6043-1 Power PC Board.
• 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.
• A small spark is objectionable if electrode touches
work just after the trigger is released.
