ESAB’S RobustFeed AVS ECHO automatic voltage-sensing wire feeder, which premiered at FABTECH 2024, is now in stock and available through welding supply distributors (find a dealer) and online retailers. ESAB’s new “ECHO” communication technology allows voltage adjustment at the feeder without a communication/control cable to the power source. The RobustFeed AVS ECHO works with the Warrior 500i CC/CV multiprocess welder with the ECHO technology upgrade option.
“The RobustFeed AVS ECHO enables operators to adjust both voltage and wire feed speed at the feeder to increase setting accuracy and improve productivity by eliminating trips to the power source to adjust voltage,” says Jeff Chittim, Senior Product Manager, ESAB. “Users can save hundreds of hours per year, as well as enhance safety by reducing movement.”
Key Product Features and Benefits:
- On the first weld, the system performs a measurement and compensates for any losses that occur in the welding circuit for all the subsequent welds.
- Compensating for voltage drop improves accuracy when using long cables, which is common in off-shore, railcar, ship/barge, construction and repair and maintenance applications.
- AVS-style feeders eliminate the need for a communication/control cable between the power source and the feeder. The design simplifies cable management, eliminating a cable that could potentially get damaged. A rugged case with an IP54 rating shields the wire and internal components from dust ingress and water splashes from any direction.
- Can handle a maximum output of 500 amps and 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 ECHO uses a 4-wheel drive mechanism and encoder-controlled feeding for smooth wire delivery. The feeder accepts a broad variety of Tweco MIG guns.
