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-paneltwist-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.
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).
Duty Cycle | Amps. | Volts |
| | |
100% | 145 | 26 |
60% | 200 | 28 |
35% | 250 | 26 |

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