FANUC ARC Mate 120iD/12L 12kg Payload 2272mm Reach Long Arm Welding Robot 0.03mm

Overview

The FANUC ARC Mate 120iD/12L is a long-arm six-axis arc welding robot for weldments that are too large to turn between stations. A 2272 mm reach lets the torch travel the full length of a trailer frame, a racking upright or a fabricated beam without a second positioner, while the 12 kg wrist payload still accepts a water-cooled torch, wire feeder and collision sensor. Repeatability of 0.03 mm keeps torch angle and contact-tip distance stable across that longer arm.

The extended upper arm is reinforced to limit whip at full extension, and the cable path is managed so the torch bundle does not swing at the end of the reach. The robot is supplied with the R-30iB Plus controller and integrated upper-arm signals and air supply, which keeps wiring short when the arm is mounted on a travelling column or a linear track. That combination makes the long reach practical in cells that already use a track for large parts.

Comparing a long arm arc welding robot usually comes down to whether reach costs stability. On the ARC Mate 120iD/12L the 2272 mm reach, the 12 kg payload and the R-30iB Plus controller are engineered as one package, and the 0.03 mm repeatability holds at full extension. That is what lets the ARC Mate 120iD/12L arc welding robot replace a second positioner in long-part cells.

In daily production the ARC Mate 120iD/12L arc welding robot is normally paired with a two-station positioner, so the operator loads one side while the 2272 mm reach welds the other. The 12 kg payload covers the torch package without derating, and the 0.03 mm repeatability is checked with a TCP test after any collision. Because the long arm shares the R-30iB Plus controller and torch consumables with other ARC Mate models, spare-part stock and operator training carry over between cells.

In service, the 2272 mm reach is usually paired with a two-station positioner so loading and welding overlap. Torch consumables follow a fixed schedule, the wrist seal is inspected quarterly, and the 0.03 mm repeatability can be re-verified with a TCP test after a collision. Our engineers have commissioned long-arm ARC Mate cells in trailer, structural steel and tank fabrication, and can advise on track length, guarding and fume extraction against CE or ANSI requirements.

Key Specifications

Key Advantages

• A 2272 mm reach welds long chassis, beams and uprights in one setup, removing the need for a second positioner.
• 12 kg wrist payload carries a water-cooled torch, feeder and collision sensor at full extension.
• 0.03 mm repeatability keeps contact-tip distance even along the full length of a long seam.
• The reinforced long upper arm limits deflection at extension, so bead width stays consistent.
• Managed cable routing keeps the torch bundle from swinging at the end of the long reach.
• R-30iB Plus control with integrated upper-arm signals suits columns, linear tracks and plant PLCs.

Typical Applications

• Trailer chassis, tank shells and long vehicle frames
• Warehouse racking uprights and long shelving
• Structural beams, columns and fabricated girders
• Stainless steel tanks, ducting and process pipework
• Agricultural trailers and implement frames
• Rail and transport sub-assemblies with long seams

Frequently Asked Questions

Q: What payload does the ARC Mate 120iD/12L carry?
A: The rated payload at the wrist is 12 kg, covering a water-cooled torch, wire feeder, collision sensor and bracket at full reach.

Q: How much does the 2272 mm reach cover?
A: The 2272 mm reach handles long chassis, beams and uprights in a single setup, so a second positioner or re-clamp is often unnecessary.

Q: Does the longer arm affect accuracy?
A: Repeatability is 0.03 mm, and the reinforced upper arm limits deflection at extension so torch angle stays stable along the seam.

Q: Can it be mounted on a linear track?
A: Yes. The arm can sit on a travelling column or linear track to extend coverage further along very long weldments.

Q: Which controller and power supply are used?
A: The R-30iB Plus controller is standard and the robot runs on a 380-575 V three-phase supply at 50 or 60 Hz.

Q: What protection is provided?
A: The body is IP54 rated and the wrist IP67, which suits general fabrication shops with spatter and dust.

Q: What is included with the unit?
A: Manipulator, R-30iB Plus controller, cables, documentation and a test report. Torch, feeder and positioner are quoted separately.

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

When a long weldment is involved, the 12 kg payload, 2272 mm reach and 0.03 mm repeatability of the ARC Mate 120iD/12L are usually specified together, because reach only pays off if the torch package still fits at full extension.
