NEW ESAB ARISTO EDGE ROBOSYSTEM STREAMLINES AUTOMATION INTEGRATION - FEATURES ADVANCED GMAW WELDMODES FOR HIGH-QUALITY WELDS

North Bethesda, Md. – The ESAB RoboSystem automated GMAW welding package features the next-generation Aristo® Edge 500R power source and RoboFeed Edge robotic wire feeder. It also features the ESAB Connect browser-based user interface, an automation gateway with support for the seven most common communication protocols, a variety of torch options and simplified cable dressing kits for leading robotic arms. The components use high speed, low latency communications to support fast, effective process control and coordination between connected devices. 

An innovative mounting design enables fast installation of the RoboFeed Edge feeder on hollow wrist and standard arm robots, and features such as programmable buttons on the torch allow for easy adjustments, such as for setting a specific wire stick-out. The user interface is easy to navigate and understand, and the service mode can be activated from the feeder to simplify routine maintenance. The ESAB RoboSystem also features built-in connectivity for InduSuite applications such as WeldCloud Fleet, WeldCloud Productivity and WeldCloud Assembly. 

“The ESAB RoboSystem streamlines implementation for system integrators and end-users because we preconfigured it for major robotic brands,” says Petter Svensson, Global Director Robotic Welding, ESAB. “To further simplify usage, ESAB developed GMAW WeldModes that provide high quality welds with minimal adjustments needed.”

Advanced Processes

In addition to conventional GMAW process, the Aristo Edge 500R features five advanced GMAW WeldModes with tailored waveforms — THIN, ROOT, ROOT Pipe, SPEED and Advanced Pulse WeldMode. All WeldModes enhance arc stability, offer more control at faster travel speeds and reduce spatter by up to 85% (depending on the processes compared) for less post-weld clean-up. Compared to conventional short circuit transfer, the THIN WeldMode reduces heat input, typically by 20%, to minimize distortion when welding thin plates, such as from 22 to 11 gauge. It also reduces spatter and fume generation. 

The SPEED mode creates a more focused arc by taking a conventional spray transfer arc and overlaying a modified pulsed current wave form on top. Benefits of the SPEED mode include improved control at higher travel speeds (up to 70 inch/min), reduced spatter, deeper more focused penetration in fillet welds and the ability to weld in narrower grooves. The Aristo Edge 500R also offers synergic Pulse MIG WeldMode, which generates up to 70% less fume compared to generic pulse waveforms. 

With an ability to bridge gaps, the easy-to-control ROOT WeldMode is optimized for root passes on plates in all welding positions and creates a smooth arc even while weaving. The ROOT Pipe WeldMode optimizes gap bridging in vertical down pipe applications. 

“The Aristo Edge platform also enables ESAB engineers to create additional, application specific WeldModes and add synergic lines to existing WeldModes, giving users the confidence of buying a future-proof system,” says Svensson. 

Within the Aristo Edge 500R power source, a next-generation current control module controls the arc more quickly than the microprocessor controls used on other pulsed welding equipment. As a result, it can detect and clear a short circuit or manage current transients 10 to 20 times faster. The system minimizes weld spatter and creates a stable, more controllable weld pool, and can deliver a stable welding arc even if mains (primary) current fluctuates.

Next-Generation Feeder

RoboFeed Edge features ESAB’s PreciDrive wire drive system to deliver reliable arc starts and stops and consistent wire feeding performance with solid wires up to 0.63 in (1.6 mm). Internal LED lights illuminate the feed mechanism for easy and safe exchange of feed rollers. It uses a special drive mode for the motor, an encoder for precise positioning and has little to no backlash in the gears. The 4-wheel drive system uses larger diameter drive rolls that offer more gripping area and provides more pushing force without deforming soft wires, a common source of feeding problems.

Digital Gas Control

RoboFeed Edge integrates gas flow sensing and control technologies that improve uptime, performance and WPS/PQR compliance. TrueFlow™ digital gas control technology ensures flow rates stay within the WPS. It also eliminates gas surges during arc start to prevent porosity and minimizes gas waste because users can define the flow rate for each weld schedule.

Instead of a standard solenoid valve with open/closed positions, the RoboFeed Edge feeder uses TrueFlow™ digital gas control technology with a proportional flow valve to provide variable control. Combined, they can precisely and rapidly control gas flow to eliminate gas surges during arc start, minimize gas waste and ensure WPS compliance. TrueFlow also helps prevent weld defects due to insufficient gas flow or gas-out situations. RoboFeed Edge can also provide high-volume air blow-out to remove spatter from the gas nozzle, tip and diffuser after the spatter is broken up by an automatic torch cleaning station, such as the Jetstream from ESAB.
