CONNECTING WIRE FEEDER TO
THE CV-300
Based on the type of wire feeder being used follow the
directions for connecting it to the CV-300.
The CV-300 is intended for use with the LN-7, LN-742,
and LN-25 wire feed units. Use the Cables/Kits listed
below to make connection easily:
FIELD INSTALLED ACCESSORIES
NOTE: The instructions for installing and operating
each accessory is included with the accessory.
REMOTE VOLTAGE CONTROL (K857)
The K857 Remote Voltage Control consists of a control
box with 25 feet (7.6 m) of four conductor cable.
Installation of a K857 Remote Voltage Control in the
CV-300 requires a K864 Remote Control Adapter.
Refer to the instructions provided with the K857 for
hookup to the CV-300. When properly connected and
the CV-300 LOCAL/REMOTE SWITCH in the
"Remote" position, the K857 functions the same as the
CV-300 Voltage Adjust control. This enables minimum
to maximum output voltage adjustment of the CV-300.
ONE CYLINDER UNDERCARRIAGE
(K835)
The undercarriage includes front casters, a handle, a
bracket, and a rear wheeled platform that is capable of
carrying one gas cylinder. The CV-300 lifting eye is not
functional with the K835 undercarriage installed.
TWO CYLINDER UNDERCARRIAGE
(K874)
The two-cylinder undercarriage platform type can
accommodate either one or two gas bottles, or one gas
bottle and a Magnum water cooler. The CV-300 lifting
eye is not functional when the K874 undercarriage is
installed.
WIRE FEEDER SWIVEL MOUNT (K178-1)
This allows an LN-7 or LN-742 to be securely mounted
on the roof of a CV-300.
UNIVERSAL ADAPTER (K867)
This provides a means of connecting auxiliary equip-
ment to the wire feeder receptacle on the CV-300
power source. It consists of a 14-pin MS-type
(Amphenol) plug with 8-inch (0.2 meter) long flex
leads, one for each circuit present in the wire feeder
receptacle. This adapter is not required when using a
standard Lincoln Electric wire feeder input cable, such
as a K480.
