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 correspon - ding 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.
