SIASUN Industrial Robot Arm with 1465mm Reach, 12kg Max Payload, 6 DOFs (SR12A-12/1.46)
A heavy spot welding gun on the end of a long arm is one of the hardest jobs an industrial robot can do. Every weld means stopping hard, holding a heavy tool still while the electrodes close, then accelerating to the next point. Any flex or vibration in the arm shows up as lost cycle time or inconsistent welds. The SIASUN SR360A-280/3.20 is built around that problem: a 280 kg payload, 3200 mm of reach, and a drivetrain designed to stay stiff and settle quickly at every stop.
Background
SIASUN is a Chinese robotics manufacturer whose industrial range covers small payload arms, SCARA robots, collaborative robots and heavy payload six axis robots for automotive, machinery and logistics work. The SR360A series sits in its large payload range. The model name follows SIASUN's convention of series, payload in kilograms and reach in meters, so the SR360A-280/3.20 is the SR360A platform configured for 280 kg and 3.20 m.

Features
High Rigidity
The J5 wrist axis uses a backlash free reducer. Removing play from the wrist improves the stiffness of the whole arm and reduces the vibration that appears when a heavy tool starts and stops, which helps the robot settle faster at each weld or placement point.
High Speed
SIASUN fits the arm with its own high torque motors. According to the manufacturer, this raises spot welding rhythm by more than 10%, so a cell can complete more welds in the same cycle time.
Easy Maintenance
The arm uses a counterweight free design. Without a counterweight assembly, there are fewer parts moving at high frequency, which lowers the chance of mechanical failure and reduces maintenance points.
Easy Deployment
The control cabinet supports mainstream industrial communication protocols and has space reserved for an external axis driver. That makes it simpler to add a track, positioner or servo welding gun axis and to connect the robot to existing line control.
Sealed Wrist
An IP67 rated wrist protects the end of the arm against dust and water, which matters in welding cells, gluing stations and washdown prone environments.
The SIASUN Large Payload Range
| Model | Payload | Reach | Best fit |
|---|---|---|---|
| SR360A-360/2.83 | 360 kg | 2830 mm | Heaviest loads where a shorter reach is enough |
| SR360A-280/3.20 | 280 kg | 3200 mm | Heavy tools that must cover a large work envelope |
| SR270A-220/3.21 | 220 kg | 3210 mm | Long reach with a lighter tool |
| SR270A-270/2.70 | 270 kg | 2700 mm | Heavy handling in a compact cell |
| SR220A-125/3.10 | 125 kg | 3100 mm | Long reach for medium weight tools |

Applications
- Automotive spot welding: carrying heavy servo welding guns across body in white assemblies.
- Heavy part handling: moving castings, frames, panels and assemblies between stations.
- Machine loading and unloading: tending presses, machining centers and fixtures with large parts.
- Assembly: positioning heavy components for joining or fastening.
- Gluing and sealing: applying adhesive along long seams on large parts.
- Machinery and shipbuilding welding: working on large weldments that need long reach.

Who Should Buy the SIASUN SR360A-280/3.20?
Buy the SR360A-280/3.20 if your process combines a heavy end effector with a large work area: spot welding lines with heavy guns, handling cells moving large parts, or loading stations where the robot must reach across fixtures. It suits automotive suppliers, machinery builders, metal fabricators and system integrators designing heavy duty cells.

Before You Buy
- Calculate the full load: add the tool, cables, dress pack and part weight, and check the wrist moment and inertia limits on the full datasheet, not only the 280 kg payload figure.
- Map your work envelope: confirm that 3200 mm reaches every point with the tool in the right orientation, including at the edges of the envelope.
- Check tolerance needs: confirm repeatability and path accuracy figures against your process requirements.
- Plan the foundation: a heavy payload robot needs a suitable floor or base; ask for mounting loads and anchoring requirements.
- Plan external axes: if you need a track, positioner or servo gun, confirm the driver and controller options.
- Confirm communications: check that the controller supports the fieldbus or industrial Ethernet protocol your line uses.
- Plan safety: budget for guarding, light curtains and a risk assessment that meet local regulations.
