How to choose a configuration
| Decision point | Selection guidance |
|---|---|
| Payload | Start with the combined mass of the end tool, mounting bracket, cables carried by the wrist, and workpiece. CR5A is rated for up to 5 kg, CR10A for up to 10 kg, and CR12A for up to 12 kg. The final combination must also remain within the applicable payload curve. |
| Working radius | Compare the required tool path and fixture access with the working radius: 900 mm for CR5A, 1300 mm for CR10A, and 1200 mm for CR12A. The highest-payload model does not have the longest reach. |
| Repeatability | The manual lists ±0.02 mm repeatability for CR5A and ±0.03 mm for CR10A and CR12A. Treat this as robot repeatability, not a guarantee of finished-process accuracy. |
| Maximum linear speed | The listed maximum linear speed is 2 m/s for CR5A, CR10A, and CR12A. Actual operating speed depends on the programmed path, payload, installation, risk assessment, tooling, and process requirements. |
| Installation | All three models support upright, ceiling, side, or any-angle installation. Non-upright installation requires mounting-angle calibration in the control software after power-on. |
| End tool and communication | Confirm the tool flange, required digital and analog signals, RS485 use, wired communication protocol, and whether Wi-Fi setup access is required before selecting the final model and accessories. |
A payload/reach comparison is only the first selection step. Confirm the complete tool center of gravity, payload curve, working envelope, mounting structure, and application risk assessment before ordering.

Before using it with a handheld laser welder
A Dobot CR Series robot can only be considered for a handheld-laser-welder integration after the complete system has been engineered and assessed. The robot listing by itself does not include or promise a laser welding package.
| Integration item | What to confirm |
|---|---|
| Payload and center of gravity | Include the laser head, mounting bracket, wire-feeding components if used, cables, gas lines, and all wrist-carried hardware. Check the applicable Dobot payload curve. |
| Mechanical mounting and TCP | Design a rigid flange-compatible bracket and establish a repeatable tool center point. Verify stiffness, collision clearance, service access, and the robot working envelope. |
| Fiber, cable, and hose routing | Plan routing through the full robot motion range without exceeding the fiber or cable bend limits or creating pull, twist, pinch, or collision risks. |
| I/O and process sequence | Map laser enable, emission, gas, wire feed, cooling status, alarms, and emergency-stop behavior to the available robot and controller interfaces. |
| Laser safety | Complete a separate laser-safety assessment covering enclosure or controlled area, interlocks, emergency stops, protective equipment, fume extraction, and applicable local requirements. |
Important: robot payload, reach, and I/O specifications do not establish compatibility with a particular handheld laser welder. Confirm the complete mechanical, electrical, process, and safety design before purchase or installation.

FAQ
| Which model should I choose? | Compare the complete wrist-carried payload and required reach first. CR5A is rated for 5 kg with a 900 mm working radius, CR10A for 10 kg with a 1300 mm working radius, and CR12A for 12 kg with a 1200 mm working radius. Check the applicable payload curve and working envelope before ordering. |
| Does the payload rating include the workpiece? | Yes. Selection must account for everything carried by the robot, including the end tool, mounting bracket, wrist-carried cables or hoses, accessories, and workpiece. The center of gravity must also remain within the applicable payload curve. |
| Is this listing a complete laser welding or arc welding system? | No. This listing is for the selected Dobot CR A Series robot configuration. A welding source, laser source, welding head or torch, wire feeder, chiller, gas system, fixtures, guarding, and process integration are not represented as included unless they are specifically confirmed in the final order scope. |
| Can I mount a handheld laser welding head on the robot? | It may be considered only after engineering review. Confirm payload and center of gravity, flange-compatible bracket, tool center point, fiber and cable routing, I/O sequence, cooling, gas, emergency-stop behavior, guarding, and laser-safety requirements. |
| Can the robot replace a dedicated CNC laser cutter? | No. A six-axis robot and a dedicated CNC laser cutting machine have different working envelopes, motion systems, process integration, accuracy considerations, and safety requirements. Select the machine architecture according to the actual cutting or welding process. |
| Does the listed price include tooling and integration? | Do not assume so. End tools, brackets, fixtures, sensors, vision, welding or laser equipment, guarding, installation, programming, commissioning, training, packing, freight, taxes, and destination-specific requirements must be confirmed separately unless stated in the final quotation. |
| Can it be installed on a wall or ceiling? | The manual specifies any-angle installation. Non-upright installation requires mounting-angle calibration in the control software after power-on, a sufficiently strong mounting structure, and anti-fall measures for wall or ceiling mounting. |
| What controller is used with these models? | The CRA Series manual lists the DOBOT CC262 AC or DC controller for CR3A through CR16A. Confirm the required controller version and input power when placing the order. |
| What communication interfaces are available? | The CC262 provides Ethernet interfaces for TCP/IP, Modbus TCP, EtherNet/IP, and Profinet, plus RS485 for RS485 and Modbus RTU. It also provides USB interfaces, an ABZ incremental-encoder input, and a Wi-Fi antenna for wireless connection to a computer or tablet during setup and debugging. Confirm the required protocol and I/O mapping for the application. |
| What information should I send before ordering? | Send the intended application, part and fixture drawings, end-tool mass and center of gravity, required reach and path, installation orientation, accuracy and cycle-time targets, I/O and communication requirements, site conditions, safety concept, and delivery destination. |
| Can suitability be guaranteed before the application is reviewed? | No. Payload and reach are only the first checks. Final suitability depends on the complete tooling, center of gravity, payload curve, working envelope, mounting structure, process requirements, controls, and application risk assessment. |
Before ordering
Confirm the required payload, payload center of gravity, working radius, installation orientation, working envelope, end tool, fixtures, I/O, communication method, and local safety requirements. The payload curve—not payload mass alone—determines whether a tool and workpiece combination is suitable.
