WIRE FEEDER FEATURES:

Wire Loading - Adjustable brake spindle mounts
Readi-Reel® Adapter, included with WIRE-MATIC 255,
or most any 2" (51mm) I.D. wire spool.
Accommodating standard 12" (305mm) and 8"
(203mm) diameter coils, the spindle’s adjustable brake
provides appropriate dereeling drag to prevent wire
reel overrun and loop-offs.

Tachometer Controlled Wire Drive - Precision con-
trol of permanent magnet motor provides proper wire
feed acceleration and speed accuracy, independent of
fluctuations in line voltage and wire loading. This gives
reliable arc starting and weld consistency.

Selectable Run-In Start-Up - A user selectable fea-
ture allows the wire feeder to feed wire directly at the
selected speed, (factory selected), or when the trigger
is pulled the wire feeder feeds wire at slow speed
regardless of the set wire feed speed until welding cur-
rent is drawn or 2 seconds has expired. This feature
enhances starting and makes setting stick out a snap
The 2 second limit permits high speed loading of the
gun and cable.

Solid State Overload Protection - No circuit breaker
to reset. Simply pull the trigger to resume welding
once the overload condition has been cleared.

Unique Drive Roll and Guide Tube Design -
Precisely aligned guide tubes and drive rolls provide
long life. The design also permits quick reload by sim-
ply starting wire into ingoing guide tube. Adjustable
tension setting minimizes 'birdnesting', eliminates
milling through the wire, and gives positive feeding.
The double groove, reversible drive roll included with
the WIRE-MATIC 255 allows use of .030" (0.8mm)
through .045" (1.2mm) diameter wire. Drive roll kits for
other sizes and types of wire are also available.

Quick-Connect Welding Gun - Gun connector has
integrated welding power and gas connection with sep-
arate front-panel twist-lock trigger connection mount.

Gun and Cable - A 12 ft. (3.6m) GMAW gun and cable
assembly, rated 200 amps 60% duty, or 250 amps 35%
duty, is provided with the WIRE-MATIC 255. A liner,
diffuser and contact tips for .035" (0.9mm) and .045"
(1.2mm) electrodes are included.

MACHINE CAPABILITY

The WIRE-MATIC 255 is rated on the following duty
cycles based on a 10-minute time period (i.e., for 60%
duty cycle, it is 6 minutes on and 4 minutes off).

LIMITATIONS

The WIRE-MATIC 255 may not operate satisfactorily if
powered with a portable or in-plant generating system.
