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-pinMS-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.
