# FANUC ARC Mate 50iD/7L

Hardware · `ARC Mate 50iD/7L` · verification: source checked

The ARC Mate 50iD/7L is a six-axis FANUC industrial robot for arc welding, with a 7 kg maximum load capacity at the wrist and a 911 mm maximum reach. It uses the R-30iB Plus Mate Cabinet controller. The arm is built to work in harsh environments and can flip over backwards to extend the working envelope.

## Connected

- Manufacturer: [FANUC](https://machineschema.com/manufacturer/fanuc.md)
- Controllers: [FANUC R-30iB Plus Mate Cabinet](https://machineschema.com/controller/fanuc-r-30ib-plus-mate-cabinet.md)

## Safety

- Body protection is IP67 as standard and IP67 on request (option) for the wrist and J3 arm.
- If applied load on the robot exceeds 5 kg when the robot is installed on an angle, the operating area is limited by the mount angle; with payload below 5 kg there is no restriction of the operating space.
- The robot can flip over backwards, which increases the work envelope.

## Study notes

- Datasheet type designation is ARC Mate 50iD/7L; a long-arm version is listed as ARC Mate 50iD/7L Long arm.
- Repeatability of ±0.01 mm is stated as based on ISO 9283.
- Motion range table values: J1 340° (360° with hardware and/or software option), J2 245°, J3 430°, J4 380°, J5 250°, J6 720°.
- Datasheet also lists J4/J5/J6 moments (N·m) and inertia (kg·m²): 16.6/0.47, 16.6/0.47, 9.4/0.15.
- Operating space figures give J5-axis rotation centre envelope, J3-axis rear-side interference areas (7L/7LC) and a 911 mm reach radius.
- Optional torch maintenance station cleans and dresses arc welding torches automatically.
- Applications listed for the ARC Mate series include welding, material removal, aerospace, automotive and consumer goods.
