Yaskawa AR1440 12kg Payload 1440mm Reach 6 Axis Hollow Wrist Welding Robot 0.02mm

Overview

The Yaskawa MOTOMAN AR1440 is a six-axis arc welding robot aimed at shops that weld medium steel assemblies in small batches and need the same result on the tenth part as on the first. A 12 kg payload leaves headroom for a water-cooled torch, a pull-type wire feeder and a collision sensor on the same wrist, while the 1440 mm reach lets the torch travel around a sub-frame or bracket without moving the fixture. Repeatability of 0.02 mm is the tightest in this class, so contact-tip distance and travel angle stay where the programmer set them.

The hollow wrist carries the torch bundle inside the arm, which is what allows the wrist to rotate freely in a deep box section instead of fighting a cable loop. The arm is supplied on a YRC1000 controller with EtherNet IP, PROFINET and DeviceNet, and it uses the same flange pattern as the rest of the AR family, so a spare unit can drop into an existing cell without rewiring. We verify torch TCP, wrist sealing and a test weld before dispatch, and we can advise on positioner, fume extraction and guarding so the cell meets CE or ANSI safety requirements.

Day to day, the AR1440 is maintained like any Yaskawa arc welding robot: torch consumables are replaced on a schedule, the hollow wrist seal is checked each quarter, and axis lubrication follows the YRC1000 service interval. Because the 12 kg payload and 1440 mm reach are matched to a standard welding package, replacement parts and torch necks are easy to source, and the 0.02 mm repeatability can be re-verified with a simple TCP test after any collision.

Buyers comparing the AR1440 with other arc welding robots usually focus on one trade-off: how much payload is left after the torch is fitted. Here the 12 kg payload, the 1440 mm reach and the hollow wrist are specified together, so the welding package fits without compromise and the 0.02 mm repeatability is available at full extension rather than only close to the base.

Key Specifications

Key Advantages

• The 12 kg payload carries a water-cooled torch, wire feeder and collision sensor together, with capacity left for a heavier torch neck.
• Repeatability of 0.02 mm is tight enough for thin-gauge work where a drifting contact tip burns through the sheet.
• A 1440 mm reach covers medium frames and still gets past ribs, gussets and stiffeners in one setup.
• The hollow wrist keeps the torch cable inside the arm, so the wrist turns through deep box sections without cable snag.
• Floor, wall and ceiling mounting lets one arm model fit a new cell or replace an ageing welder on a crowded line.
• YRC1000 control with EtherNet IP, PROFINET and DeviceNet connects to common PLC, positioner and safety hardware.

Typical Applications

• Automotive sub-frames, cross members and exhaust assemblies
• Furniture frames, shelving and display stands
• Structural steel brackets, railings and scaffolding
• Stainless steel kitchen and food processing equipment
• Agricultural implement frames and trailer chassis
• Aluminium profiles and light transport structures

Frequently Asked Questions

Q: What payload can the AR1440 carry?
A: The rated payload is 12 kg, enough for a water-cooled torch, pull-type wire feeder, collision sensor and bracket on one wrist.

Q: What does 0.02 mm repeatability mean in practice?
A: The arm returns to the taught point within 0.02 mm, so contact-tip distance and torch angle stay constant and thin-gauge sheet is less likely to burn through.

Q: How much area does the 1440 mm reach cover?
A: The 1440 mm reach covers medium frames and lets the torch work around ribs and gussets without repositioning the fixture.

Q: Why does the hollow wrist matter for welding?
A: The torch cable and hose run inside the arm rather than looping outside, so the wrist rotates freely in deep sections and the cable lasts longer.

Q: Which controller and networks are supplied?
A: The YRC1000 controller is standard, with EtherNet IP, PROFINET and DeviceNet for PLC, positioner and safety integration.

Q: Can it weld aluminium and stainless?
A: Yes. With a matched power source and programme the arm runs MIG MAG, TIG and flux cored welding on carbon steel, stainless and aluminium.

Q: What is included in the package?
A: Manipulator, YRC1000 controller, connecting cables, documentation and a test report. Torch, feeder and positioner are quoted to suit the application.

Q: How is the robot shipped and supported?
A: It ships in an export wooden crate with shock absorbing packing. We provide commissioning guidance, spare parts and remote diagnostics.
