S-420iF Information

The low mass of the FANUC S-420iF arm is ideal for spot welding. It offers high-speed positioning and fast motion speeds, resulting in high throughput and less time between welds.

The S420iF RJ2 has a straightforward design with few components for ease of maintenance and changeability.

RobotWorx also offers a variety of of refurbished robots, including the used FANUC S-420iF. The used S-420iF has undergone a rigorous refurbishment process and comes with the RobotWorx Value Package

While this FANUC robot excels at spot welding, the new or used S 420iF RJ2 is versatile enough to perform other applications including machine loading and unloading, material handling, and parts transfer.
