News / Yaskawa Motoman Introduces SP-Series Robot Line to Optimize Spot Welding Productivity

Dayton, OH (September 2018) — Designed for exceptional spot welding performance, the new SP-series robots offer exceptionally fast axis speeds and acceleration to reduce air-cut time and increase production output. Now available in five models – SP80, SP100, SP165, SP165-105 and SP210 – these six-axis robots are powerful and efficient.

Offering improved acceleration/deceleration control for all axes, the SP-series robots enable improved productivity. 
While high allowable moment of inertia ratings provide substantial wrist rigidity, a wide wrist motion range eliminates interference and improves application flexibility.

A slim profile design allows SP-series robots to reach into confined spaces, facilitating close proximity placement of robots for high-density layouts. An integrated spot harness improves wrist flexibility and reduces downtime for all five robot models as well.

SP-series robots are equipped with servo gun and DC timer technology to optimize productivity and consistent weld quality. Spot monitoring and waveform graphing helps troubleshoot welding conditions, and controller connectivity provides simple wiring to spot timers and robot pendant weld programming for Medar® and Nadex® brand timers.

Installation is quick and efficient. A single cable is all that is needed to connect the manipulator to the controller, resulting in easy setup and reduced expenses for maintenance and spare parts inventory. Equipped with an IP67-rated wrist and an IP54 body standard, each robot can be floor-mounted.
   SP80  SP100  SP165  SP165-105  SP210
Axes  6  6  6  6  6
Payload (kg)  80 kg  100 kg  165 kg  105 kg  210 kg
Payload without Spot Harness (kg) 88 kg 110 kg 180 kg 120 kg 225 kg
Horizontal Reach (mm) 2,236 mm 2,236 mm 2,702 mm 3,058 mm 2,702 mm
Vertical Reach (mm) 3,751 mm 3,751 mm 3,393 mm 4,105 mm 3,393 mm
Repeatability (mm) ±0.07 mm ±0.07 mm ±0.2 mm ±0.2 mm ±0.2 mm

Uniquely, designed for large part processing, the extended reach SP165-105 can eliminate the need for a linear track, reducing system cost and simplifying programming. Also, the SP165, SP165-105 and SP210 models do not include a counterbalance, reducing the mass of the robot arm and enabling higher acceleration, deceleration and speed.

SP-series robots are controlled by Yaskawa’s high-performance YRC1000 controller that is built to a global standard and does not require a transformer for input voltages ranging from 380VAC to 480VAC. The YRC1000 is highly compact (598 W x 490 H x 427 D mm), resulting in reduced space requirements.
