ESAB RobustFeed AVS

SKU: 0446700881

The industry’s most durable and high-performing industrial wire feeder is now available for any brand of CC/CV power source or engine-driven welder. Using automatic voltage sensing (AVS), you’ll have best-in-class feeder performance, portability, and usability. Start taking on the toughest environments with RobustFeed AVS.

RobustFeed AVS

RobustFeed AVS has voltage-sensing feeder, which eliminates the need for a power supply/control cable between the power source and the feeder. The design simplifies cable management in portable applications, eliminating a cable that could potentially get damaged. Voltage-sensing feeder technology also enables the feeder to work with either constant current (CC) or constant voltage (CV) power sources for greater flexibility.

Ergonomic and Operator Friendly

When carried by the middle handle, RobustFeed rests comfortably against the side of the operator’s body when walking longer distances. The RobustFeed has three crane certified handles and two additional lifting points for best-in-class portability and maneuverability. Its front and rear handles make it easy to carry up a ladder, maneuver through confined spaces or pass the unit from one person to another. For greater mobility, the RobustFeed AVS has an optional wheel kit that mounts on either the bottom or side of the feeder. To keep digital meters oriented for easy viewing (e.g., horizontally), the control panel can be rotated 90 degrees with the removal of two screws.

With RobustFeed , operators use a single control knob and digital meter on the front panel to adjust wire feed speed at the feeder (but must set voltage at the power source). The RobustFeed AVS has two internal LEDs to illuminate the feeder in dark conditions, 2T (standard) or 4T (trigger lock) control, gas purge, wire jog, CC/CV mode switch and an optional internal gas flow meter protected by the rugged case.

The RobustFeed AVS accepts 8- and 12-in. diameter wire spools, measures 23.4 x 9.8 x 16.9 in. and weighs 40.5 lbs. It feeds solid wires as large as 5/64 in., cored wires up to 3/32 in. and has a wire feed speed range of 32 to 984 inches per minute. It has a duty cycle rating of 100% at 350 amps, the best in its class Where other portable feeders only have 2-wheel drive, the RobustFeed AVS uses a 4-wheel drive mechanism and encoder-controlled feeding.

IP44 Protection Rating

RobustFeed AVS with its IP44 rating is truly weather restistant. You can leave this feeder in the rain or drag it through the dirt and it will continue to perform reliably.

Regardless of power source brand, using a RobustFeed AVS when you want a voltage-sensing style feeder improves uptime and productivity.

Featuring a completely-sealed wire feed compartment that protects the wire and internal components from water splashes in all directions. The seal also keeps out dirt, grinding dust and other particles than can damage feeder components or degrade the wire and contaminate the weld pool.

The controls, as well as the power and gas cable connections, are also protected inside the housing. On the outside, the feeder uses a double-wall design that has special zones to provide abrasion and impact resistance, while a reliable strain relief removes cable stress.

Optimized Usability.

Reduce downtime on the jobsite with color-coded drive rollers, tool-free change-outs, and spare parts storage. RobustFeed AVS’s double-door design provides easy access to cable connections, built-in gas flow meter, and dust-proof electronics compartment.

Superior Performance.

Industry-leading duty cycle, wire diameter, and speed give you the feeder performance and power you need to weld the widest range of material thicknesses. Plus, a self-feeding, 4-wheel drive roll system guarantees smoother, more reliable wire feeding than the traditional 2-wheel system.

Limitless Portability.

Carry, lift, or drag RobustFeed AVS anywhere with ease thanks to its five sturdy comfort-grip handles and lifting points with integrated cable strain relief protection. Optional flat and vertical wheel kits allow for even greater mobility.
