SAFETY PRECAUTIONS
ELECTRIC SHOCK can kill.
•Only qualified personnel should per-
form this installation.
•Turn the input power OFF at the dis-
connect switch or fuse box before work-

this equipment
LOCATION
The MIG Pulser can be used in the same locations and
environments as the V300. It is rated for use in damp,
dirty environments.
MOUNTING BRACKETS
Locate the two mounting brackets and rubber bumper
with screw that are supplied with the MIG Pulser in the
loose parts bag. To prevent accidentally dropping the
unit, always secure the MIG Pulser to a stable surface
with one of the brackets.
The first bracket is designed to “hook” onto the front
handle of the V300, allowing the MIG Pulser to be
located next to the V300 Control Panel.
Attach this
bracket as shown in figure A.1a by using the two
screws from the top of the MIG Pulser. To prevent the
MIG Pulser from scratching the paint off the V300, affix
the rubber bumper to the bottom corner of the MIG
Pulser case with the longer provided screw.
The second bracket is a universal bracket that is
designed to allow the MIG Pulser to be fastened to any
secure surface. Attach the bracket to the desired sur-
face. Then attach the MIG Pulser to the universal
bracket using the two screws from the top of the MIG
Pulser as shown in figure A.1b.
HIGH FREQUENCY INTERFERENCE
PROTECTION
A V300 with a MIG Pulser may not be suitable for use
near a high frequency arc starter (such as is found in
a TIG welding power source or a plasma cutter). The
V300 should be located at least 15 feet (5 meters) from
the high frequency source.
There should be at least
25 feet (7.5 meters) or greater separation between the
ground connections and welding or cutting arcs of the
V300 and the high frequency source.
ELECTRICAL INPUT CONNECTIONS
MACHINE GROUNDING
The MIG Pulser is grounded to the V300 by the ground
lead carried inside the Control Cable. Ground the V300
according to all local and national electrical codes.
Also refer to the V300 operator’s manual for any other
grounding considerations.
SUPPLY CONNECTIONS
The MIG Pulser receives its input power from the V300
through the Control Cable.
CONNECTION TO A V300
Turn the Power switch on the V300 “OFF” before con-
necting or disconnecting input power lines, output
cables or control cables.
------------------------------------------------------------------------
CONTROL CABLE CONNECTION
The MIG Pulser is supplied with a “wye” adapter for
making connections to the V300.
The 14-pin plug
should be inserted into the V300 Wire Feeder recepta-
cle, the 14-pin socket is for the wire feeder Control
Cable, and the 6-pin socket connects directly to the
MIG Pulser (Refer to figure A.2). If a DC TIG Starter is
attached and connected to the V300, the 14 pin Pulser
plug can be connected to the lower 14 pin socket on
the DC TIG STARTER, which is labeled “connect to
WIRE FEEDER”. Switch to “control at wire feeder” to
transfer control to the MIG PULSER.
The MIG PULSER cannot be used for TIG welding.
