Remote Voltage Control

Saves the operator a trip back to the power supply for welding adjustments. For applications where the feeder is within 100 feet of the power source and control cords are acceptable.

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. Wide voltage range for small and large wires with no contactor chatter or arc outages.

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.

Extreme Reliability

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.

Ultra-low Drag Inlet Guide Pins

Make loading the wire easy and does not deform the wire on the way into the drive rolls improving wire feeding performance.

Scaled Wire Pressure Knob

Provides easy adjustment and consistent pressure on the drive rolls and wire.

Digital Meters with SunVision™ Technology

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

How to connect welding gun:

  1. Turn off wire feeder and power source.

    Stop engine on welding generator.

  2. Connect gun.

    Loosen gun securing knob and insert gun power pin into gun block. Power pin should be as close as possible to drive rolls without touching. Align gun power pin groove with gun locking tab and tighten gun securing knob. If gun power pin doesn’t have a groove, loosen knob to rotate the gun locking tab 180 degrees to prevent dun locking tab from interfering with gun power pin when inserted into the gun block.

  3. Connect gun trigger plug to gun trigger receptacle.

    Gun is now ready for use.
