Documented examples include 310 kg / 2,800 mm, 260 kg / 3,000 mm and 240 kg / 3,200 mm, with distinct precision values. The starting price does not establish the price of every listed configuration. Where the review gives only a family precision range, this article leaves the exact-variant value for supplier confirmation rather than assigning the best family figure to every arm.
Start with the process, not the payload headline
Yaskawa Motoman SP210 is designed for resistance spot welding, while ABB IRB 6740 is a broader industrial platform. The gun, dress package, process controller and wrist inertia can dominate this comparison. A higher generic payload is not proof that the complete spot-welding package is included or suitable. The acceptance case for this pair should be: A complete spot sequence with the proposed gun, clamp operation, representative part fixture, utilities and between-weld motion. The useful outcome to measure is accepted welds, gun clearance, non-welding time and maintenance access. A supplier demonstration must use the same workpiece range, tool mass, fixtures and normal operating conditions for both proposals.
A dedicated process arm and a general-purpose manipulator can sometimes perform similar motions, yet require very different integration. A torch needs process utilities and seam access; a spot gun imposes mass, inertia and clamp requirements; a pallet tool needs stable grip and stack coverage. Include those differences before comparing robot-only prices.
Payload, wrist moments and the complete end effector
For the worked configurations, the load references are 240 kg and 210 kg. Count fingers, adapters, cameras, valves, cables carried by the wrist and the actual workpiece. A nominally permitted part can become an excessive load once its gripping hardware is added. Use the relevant load diagram rather than assuming the maximum payload is allowed at every centre of gravity.
Check moments and inertia at the worst tool orientation and during the required acceleration. Long, offset parts can create a wrist problem while staying below the mass limit. For a welding gun, include the complete utilities and balancing arrangement. For a pallet gripper, include the full layer or multiple picked cases and a credible grip-loss condition.
Workspace, axis count and required orientation
ABB IRB 6740 has 6 controlled axes and the worked reach is 3,200 mm; Yaskawa Motoman SP210 has 6 axes and 2702 mm. Equal axis counts do not guarantee equal joint limits, elbow clearance or singularity-free access. Check every required pickup, process, reject and recovery pose with the tool attached.
Use a tool-centre-point layout and include the carried-part envelope, machine doors, fixture walls, hose loops and neighboring equipment. Horizontal reach is not the same as vertical reach or useful reach below a shelf. A reachable endpoint can still fail because the wrist cannot attain the required approach angle or retreat without a collision.
ABB IRB 6740: engineering assessment
Select a configuration around the final tool and payload inertia. A higher peak family payload should not hide the installation footprint, floor-load requirements or the effect of dressing on the supplied load envelope. In this comparison, the worked configuration is IRB 6740-240/3.2, with 240 kg, 3,200 mm and the stated repeatability reference of ±0.06 mm. Its practical benefit should be demonstrated at the intended operating load rather than inferred from the family label.
Documented examples include 310 kg / 2,800 mm, 260 kg / 3,000 mm and 240 kg / 3,200 mm, with distinct precision values. Identify who owns the final RAPID program, RobotStudio project, safety settings and backups. Existing ABB experience is useful when the actual maintenance team can restore a stopped application, identify a failed component and keep the cell supported through its planned service life.
Yaskawa Motoman SP210: where the alternative adds value
Validate gun clearance, clamp forces, cable service and the non-welding travel path. Yaskawa Motoman SP210's payload number is not evidence that an equally rated palletizing or handling robot includes the same gun interface or production process. Its reviewed combination is 210 kg, 2702 mm and ±0.05 mm positioning repeatability. Spot-gun mass, inertia, utilities and process control differ from general handling or arc welding. The reviewed mechanism has six controlled axes. Establish what that configuration adds to the actual task: a useful orientation, smaller workspace, longer path coverage, specific process equipment or a more familiar controller.
The source identifies YRC1000 for Yaskawa Motoman SP210. INFORM and MotoSim form the programming and simulation route described in the review. Compare the local team's ability to create, diagnose, back up and recover the finished application rather than judging software only by a short sales demonstration.
Precision and process quality
The two positioning references are ±0.06 mm and ±0.05 mm. These concern returning to a pose under stated conditions; they are not a finished-part tolerance guarantee. Absolute accuracy, path behavior, fixture stiffness, calibration, tool wear, thermal change and workpiece variation remain separate. Where a variant-specific precision value is not documented, obtain it for the quoted order code.
Measure accepted welds, gun clearance, non-welding time and maintenance access. For welding, inspect the accepted seam or spot result using a qualified process. For handling, count stable pickup and placement throughout the fixture range. For palletizing, test stack stability and top-layer clearance. A faster unloaded movement or one successful prepared sample does not establish sustained production quality.
Controller, interfaces and error recovery
ABB OmniCore and YRC1000 are the controller references for the reviewed configurations. Controller generation affects the program format, available interfaces and support plan. Confirm the actual pendant, network roles, protocol options, external-axis support and software licences; a capability mentioned in a brochure is not proof that it is enabled in the starting package.
Prepare an I/O and network schedule for the PLC, gripper, machine, process equipment, vision and protective devices. Specify acknowledgement timeouts, safe state and restart sequence. Demonstrate a lost grip, missing part, rejected result, interrupted machine cycle and communication loss. Retain editable programs, calibration files, controller backups and a recovery guide suitable for the intended operators.
Guarding, environment and installation
These are industrial robot applications. Design the complete safeguarding concept around the robot, tools, carried part, stored energy, machine and process hazards. Safe access, stopping behavior, interlocks, isolation and restart belong in the cell design. A newer controller or an additional axis does not make an industrial application suitable for unrestricted human access.
The arm protection references are IP67 for the reviewed ABB package and Confirm exact protection package for Yaskawa Motoman SP210. An unspecified value requires exact-package confirmation. Check the cabinet, tool, connectors and dress pack separately. Ingress protection alone does not approve every coolant, abrasive exposure, chemical or high-pressure cleaning method.
Obtain the installation mass and floor reactions for IRB 6740-240/3.2; the alternative's review gives 1080 kg. Keep carried payload separate from installation mass and cabinet weight. Design the support, anchoring, lifting plan, cooling space and service route using the exact drawings. Shelf-mounted and very heavy arms can make structural work a significant part of total installed cost.
Starting price and installed-cost comparison
The numerical starting references are USD 92,000 and USD 66,000. The first is a family-level review reference; it is not assigned to the selected variant as a firm offer. New, legacy, refurbished and process-package quotations can have different scope and condition. Confirm the supplied revision, warranty, support, delivery and commissioning responsibilities before using either number in a payback calculation.
Request comparable bills of materials covering robot and controller, tool, fixtures, process utilities, sensing, safeguarding, machine interfaces, support structure, integration, simulation, commissioning and training. Include freight, tax and on-site work where applicable. Assign responsibility for faults spanning vendors. A lower arm price can be outweighed by an extra positioner, unsuitable fixture, structural change or software maintenance burden.

Begin with the actual process: spot-welding integration. Large-part handling and automotive or EV process stations. Resistance spot welding using a 210 kg robot and the required gun package. Eliminate a candidate if it cannot meet the complete load, pose, quality or safeguarding requirement. If both pass, compare useful throughput, operator changeover and the maintenance burden of the supplied system. A different robot category can be appropriate only when the whole cell concept changes with it.
Give both suppliers the same tool CAD, part range, fixture model, target output and access pattern. Agree measurable pass criteria before the trial. Use representative variation and normal safety settings; include replenishment, rejects, process interruptions and recovery after power loss. Keep the tested configuration, program and acceptance record as part of the delivered system.

Frequently asked questions
Which should I choose: ABB IRB 6740 or Yaskawa Motoman SP210?
Yaskawa Motoman SP210 is designed for resistance spot welding, while ABB IRB 6740 is a broader industrial platform. The gun, dress package, process controller and wrist inertia can dominate this comparison. A higher generic payload is not proof that the complete spot-welding package is included or suitable. Choose the complete proposal that passes the real load, process-quality, workspace and safeguarding requirements, then compare installed cost and the skills needed to maintain it.
Which ABB configuration is compared with Yaskawa Motoman SP210?
IRB 6740-240/3.2 is used as the worked configuration, with 240 kg and 3,200 mm. Documented examples include 310 kg / 2,800 mm, 260 kg / 3,000 mm and 240 kg / 3,200 mm, with distinct precision values. Confirm the full order code and generation with the supplier.
What starting prices are used?
The linked review references are USD 92,000 for ABB IRB 6740 and USD 66,000 for Yaskawa Motoman SP210. The ABB value is a family starting reference, not a quote for every variant. Confirm the current supplied package, condition, controller, process equipment, safeguarding, delivery and integration scope.
Does payload include the tool?
Yes. Include the complete end effector, adapters, attached equipment and workpiece, then verify the permitted centre of gravity, wrist moments and inertia. The worked references are 240 kg and 210 kg. A part below the mass headline can still violate an eccentric-load or inertia limit.
Are the reach and axis counts directly interchangeable?
No. The comparison uses 3,200 mm with 6 axes and 2702 mm with 6 axes. Check tool offset, required orientation, joint limits, vertical or below-base access and the full loaded path. A four-axis or five-axis mechanism does not offer every six-axis orientation.
Does repeatability guarantee process quality?
No. The positioning references are ±0.06 mm and ±0.05 mm. Measure the finished result with representative fixtures, tooling and part variation. For this comparison, the process criterion is accepted welds, gun clearance, non-welding time and maintenance access.
What is the main limitation of Yaskawa Motoman SP210?
Spot-gun mass, inertia, utilities and process control differ from general handling or arc welding. The reviewed mechanism has six controlled axes. Validate gun clearance, clamp forces, cable service and the non-welding travel path. Yaskawa Motoman SP210's payload number is not evidence that an equally rated palletizing or handling robot includes the same gun interface or production process.
What should be demonstrated before purchase?
A complete spot sequence with the proposed gun, clamp operation, representative part fixture, utilities and between-weld motion. Include machine or process interlocks, normal guarding, missed grip or rejected part, communication loss, changeover and safe restart. Retain the exact configuration, controller backup, program and agreed acceptance record from the trial.
