ArcReach Technology

Exclusive ArcReach technology uses the existing weld cables to communicate changes in voltage settings. Voltage and wire-feed-speed controls are conveniently located at the operator’s fingertips – not back at the power source.

Remote Override of power source

When an ArcReach feeder is connected to a power source the feeder has full control and the power source controls are disabled. While under ArcReach control, process and V/A adjustments are locked out, preventing accidental changes by personnel other than the welding operator.

Fleet Compatibility

ArcReach-equipped power sources and wire feeders work with non-ArcReach equipment; however the complete ArcReach benefit is only realized with the ArcReach system. This allows you to start investing in ArcReach one power source, one wire feeder at a time.

Setting the Standard for Performance

  • Heavy-duty drive motor with tachometer control provides wire feed speed that is accurate and consistent from the start of the weld to the finish and from one weld to the next, which provides consistent arc quality.
  • Front panel has trigger hold, wire jog, and gas purge for easy operator access.
  • Wide voltage range for small and large diameter wires with no contactor chatter or arc outages.

Improved Weld Quality

Operators can precisely set arc voltage at the feeder and monitor the actual arc voltage and current delivered to the weld using the digital meters on the feeder. This removes guesswork when it comes to adhering to weld procedures.

Increased Productivity

More arc-on time and reduced exposure to workplace hazards for operators can be realized using ArcReach because less time is spent going back to the welding power supply to set process and arc voltage.

Unique and Durable Case

  • Impact-resistant, flame-retardant case provides strength and durability, and protects components and welding wire from moisture, dust and other contaminants.
  • Built-in slide rails allow you to drag the feeder into position for welding.
  • Innovative feeder door design allows you can change wire while feeder is standing upright or laying down.

Digital Meters with SunVision™ Technology

Display voltage, wire feed speed, and also amperage if desired. Meters can be seen clearly even in direct sunlight.


12VS model is sized for an 8- or 12-inch spool of wire. 12-inch spools are the most common in structural steel and fabrication.

Extremely Reliable

  • Potted and trayed main printed circuit board for the harshest environment adds exceptional reliability. Board has full-trigger isolation so a shorted gun trigger will not affect feeder operation.
  • Gun locking tab works with guns having corresponding locking grooves to prevent gun from being pulled out if the feeder is dragged by the gun.
  • Gas inlet recessed into back of case is protected from incidental contact by the weld cable, ensuring consistent and contaminant-free shielding gas delivery to the gun. Double-filtered gas valve helps keep dirt from clogging and affecting gas flow.
