Robot details

The Yaskawa MOTOMAN SP225H is a high-performance 6-axis industrial robot specifically designed for spot welding applications in demanding automotive and heavy manufacturing environments. Combined with the advanced YRC1000 controller, the SP225H delivers exceptional speed, precision, flexibility, and reliability, making it one of the leading robotic solutions for automated resistance spot welding and material handling operations. 

The robot features a 225 kg payload capacity and a 2,702 mm horizontal reach, allowing it to handle large welding guns, servo welding equipment, and heavy end-of-arm tooling while maintaining high accuracy and productivity.

A key characteristic of the SP225H is its hollow upper-arm design, which enables internal routing of welding cables and hoses. This significantly reduces cable wear, minimizes interference with surrounding equipment, simplifies offline programming, and improves overall cell efficiency. 

The robot is controlled by the Yaskawa YRC1000, a compact and powerful industrial controller capable of coordinating multiple robots and external axes while providing advanced motion control, high-speed processing, simplified programming, and enhanced safety functions.

Main Applications

1. Automotive Spot Welding

The SP225H is primarily used in automotive body shops for:

• Body-in-white (BIW) production
• Car body assembly
• Door welding
• Side panel welding
• Chassis welding
• Structural component joining
• Battery enclosure welding for electric vehicles

Its high payload capacity allows the robot to manipulate large servo welding guns with excellent positioning accuracy. 

2. Resistance Spot Welding

The robot performs:

• Steel spot welding
• High-strength steel welding
• Aluminum component welding
• Multi-point welding operations
• High-volume production welding

The fast axis speeds reduce air-cut time and improve production throughput. 

3. Material Handling

Although designed for welding, the SP225H can also be deployed for:

• Heavy component handling
• Fixture loading and unloading
• Automotive parts transfer
• Manufacturing logistics
• Machine tending

A version without integrated spot harness can be used specifically for material handling applications. 

4. Automated Production Lines

The robot is ideal for:

• Automotive manufacturing
• Metal fabrication
• Transportation equipment production
• Heavy machinery assembly
• Industrial automation cells

Its slim profile enables installation in compact robotic workcells.
