SIASUN Industrial Robot Arm with 2010mm Reach, 12kg Max Payload, 6 DOFs (SR25A-12/2.01)

It is positioned as a mid-payload, long-reach robot (12 kg payload class with roughly 2.0 m reach) suited to production environments that require repeatable motion, flexible mounting, and integration with common factory automation components such as welding power sources, tool changers, sensors, and safety systems.

In typical deployments, the SR25A-12/2.01 is used as part of a workcell that includes a robot controller, end-of-arm tooling (EOAT), fixtures, guarding, and (where applicable) process equipment such as arc-welding packages or part presentation systems. SIASUN also references the SR25A-12/2.01 as a selectable robot option in pre-engineered welding “machine set” solutions for industrial fabrication workflows.

Design and Features

Mechanical architecture

The SR25A-12/2.01 is an articulated robot with six rotational axes (6 DOFs), a common configuration that enables a wide range of tool orientations and approach angles—especially useful in arc welding, machine tending, and assembly tasks that require reaching around fixtures.

Mounting flexibility

A notable feature for cell designers is multi-position installation support. The robot is listed as suitable for floor-mounted and ceiling-mounted configurations, which can help optimize footprint in crowded production lines and allow overhead reach into jigs, stations, or conveyor lanes.

Protection and industrial suitability

The SR25A-12/2.01 is listed with an IP65 protection level, which is commonly associated with dust-tight sealing and resistance to water jets—useful in industrial settings where particulate, spatter, or washdown-adjacent conditions may be present (final suitability depends on the specific process and cell design).

Technology and Specifications

Key published specifications

The following specifications are commonly used by engineers to size a robot for reach, payload, and precision requirements:

• Robot type: Articulated industrial robot

• Axes / DOFs: 6-axis

• Maximum payload: 12 kg

• Maximum reach: 2,010 mm

• Repeatability: 0.07 mm

• Protection rating: IP65

• Mounting options: Floor-mounted, ceiling-mounted

• Typical functions listed: handling, assembly, loading/unloading, welding

What these specs mean in practice

• 2010 mm reach supports larger work envelopes (e.g., reaching across wider fixtures, multiple stations, or deeper jigs) without requiring rails in many layouts.

• 12 kg payload generally accommodates many welding torches, small grippers, inspection heads, and compact process tools—while leaving some margin for brackets, cabling, and adapters.

• 0.07 mm repeatability indicates how consistently the robot can return to a taught point under defined conditions, which matters for tasks like precise torch placement, consistent part presentation, and repeatable pick points.

Applications and Use Cases

Arc welding and fabrication cells

The SR25A-12/2.01 is explicitly listed for welding applications and is also referenced by SIASUN in welding “machine set” solutions, which typically bundle robot selection with fixtures and process integration for production welding.
Common welding use cases include:

• Multi-pass weld paths on fabricated parts

• Repetitive seam welding on assemblies

• Robot-assisted welding in stations where overhead mounting improves access or reduces floor footprint

Machine tending, loading, and unloading

With a mid-range payload and long reach, the robot is suited to:

• CNC machine tending (door opening tools, part handling, infeed/outfeed)

• Press and forming station handling (where permitted by safety design)

• Conveyor pick-and-place and bin presentation workflows

Assembly and general handling

The model is also listed for assembly and handling tasks, which often include:

• Subassembly placement and light fastening operations

• Positioning parts for vision inspection or measurement

• Feeding parts into downstream processes (e.g., labeling, packaging, or secondary operations)

Industry domains

The robot is listed for automotive and electronics industry applications—two sectors that often require high throughput, repeatable motion, and reliable uptime in standardized cells.

Advantages / Benefits

Reach-to-payload balance

A 2.0 m-class reach combined with a 12 kg payload can be attractive for cells that need to service multiple points or stations without moving the robot base, especially where longer torch or gripper tooling is used.

Flexible installation for space-constrained lines

Support for both floor and ceiling mounting can simplify line layouts, improve access to fixtures, and help integrators maintain ergonomic and maintenance-friendly workcell designs.

Repeatability for consistent production quality

Published repeatability (0.07 mm) supports process consistency in many industrial operations, especially when paired with calibration, proper fixturing, and (where needed) in-process sensing such as seam tracking or vision guidance.

FAQ Section

What is the SIASUN SR25A-12/2.01?

The SIASUN SR25A-12/2.01 is a 6-axis articulated industrial robot arm designed for factory automation tasks including handling, assembly, loading/unloading, and welding, with a 12 kg payload and 2,010 mm reach.

How does the SR25A-12/2.01 work?

It operates as a programmable robotic manipulator controlled by an industrial robot controller. The robot moves through coordinated rotations across six axes to position a tool (such as a welding torch or gripper) along taught points or program-generated paths for repeatable production operations.

Why is the SR25A-12/2.01 important in industrial automation?

Robots in this class help manufacturers improve repeatability, throughput, and process consistency. The SR25A-12/2.01’s published 0.07 mm repeatability, long reach, and flexible mounting can support stable production in workcells where consistent tool positioning is required.

What are the benefits of a 2010 mm reach, 12 kg payload 6-axis robot?

A 2,010 mm reach can cover larger fixtures or multiple stations, while a 12 kg payload accommodates many industrial tools and grippers. A 6-axis configuration enables flexible tool orientation for tasks like welding and assembly where approach angle matters.

Summary

The SIASUN SR25A-12/2.01 is a 6-axis industrial robot arm characterized by a 12 kg maximum payload, 2,010 mm reach, 0.07 mm repeatability, IP65-rated protection, and support for floor or ceiling mounting. Its specification profile and listed use cases make it a practical option for welding, machine tending, assembly, and general handling in industrial automation environments where reach, repeatable motion, and layout flexibility are key requirements.
