KUKA Industrial 6-Axis High-Precision Arc Welding Robot Workstation with MIG/MAG Torch Feeder for Auto Steel Parts

Overview

• • The KUKA six-axis arc welding robot workstation is a turnkey automated welding cell built for repetitive, high-mix arc welding duty in metal fabrication shops.
• • The cell combines a KUKA arc welding robot with a KR C5 smallsize-2 controller, a low-spatter MIG/MAG power source and torch feeder, a wrist-routed welding torch, and a workpiece positioner or fixture configured to the part.
• • Payload options of 6 kg, 8 kg and 12 kg cover torch packages ranging from air-cooled guns to water-cooled torches fitted with collision sensors and seam tracking.
• • A repeat positioning accuracy of 0.04 mm and a maximum reach of 2010 mm keep torch alignment stable on long structural members as well as on tight automotive brackets.
• • Dedicated low-spatter MIG/MAG schedules for carbon steel, stainless steel and aluminium let mixed-material batches run in one cell instead of two.
• • Every unit is released with a machinery test report and a video outgoing inspection, and the supplier supports cell integration plus weld schedule setup at commissioning.
• • The workstation is delivered as a single item with a 1-year warranty, online technical support, pre-production samples before mass production, and final inspection before shipment.

Technical Specifications

Advantages

Multi-material coverage in one cell

• • Low-spatter MIG/MAG schedules for carbon steel, stainless steel and aluminium run from the same power source and the same robot program structure.
• • Thin-gauge sheet batches and multi-pass thick-plate work share one footprint, so buyers do not build a second station for mixed-material orders.
• • Torch angle, travel speed and heat input are stored per material, keeping parameter recall consistent between shifts and between operators.

Stable seam quality across long runs

• • 0.04 mm repeat positioning accuracy and a stiff arm design hold torch alignment through long production runs, cutting touch-up grinding on visible welds.
• • Consistent heat input and travel speed limit distortion on thin-gauge parts, which protects dimensional tolerance and reduces rework loops.
• • Wrist-routed torch cabling removes cable whip from the working envelope, so the torch package stays predictable in tight fixtures.

Compact cell with flexible mounting

• • The compact cell can be mounted on the floor, on the ceiling or on a wall, and can sit beside a positioner or under an existing fixture.
• • Cable routing through the wrist reduces snag risk in narrow fixtures and supports retrofits into existing lines without rebuilding the layout.
• • A single-item package of 95 x 95 x 300 cm and 530 kg gross weight keeps shipping and site handling straightforward for a full welding cell.

Fieldbus-ready electrical integration

• • Native PROFINET and EtherCAT support connect the cell directly to common PLC architectures, with EtherNet/IP and safety protocols available as options.
• • Motion control, safety logic and welding sequence run from one controller chain, avoiding the mismatch between a robot controller and a third-party weld timer.
• • One spare-part and support path covers robot, controller and welding package, simplifying maintenance planning for the plant team.

Configured around the part, not the catalogue

• • Fixture design, cycle planning and torch accessibility are worked out together with the full cell layout, so reach and payload are validated before the order is released.
• • Drawing-based, sample-based and full customization are supported for workpiece geometry, positioner type and line layout.
• • The supplier has delivered robot cells since 2016 and offers positioners, linear tracks, dress packs, grippers and torch-cleaning devices as matching peripherals.

Applications

• • Automotive parts such as brackets, seat frames, exhaust assemblies and chassis components welded in medium to high volumes.
• • Steel structures and construction components including beams, columns, trusses and connection plates with long, visible weld seams.
• • Shipbuilding and offshore components where multi-pass welding, distortion control and traceable weld quality are contractual requirements.
• • Construction machinery frames, booms and attachments produced in mixed batches with frequent changeover.
• • New-energy structural parts such as battery housings, frames and support brackets in aluminium or stainless steel.
• • Job shops and integrators that need a repeatable arc welding cell with fixture design, cycle planning and weld schedule support included.

FAQ

Q: Which model should I choose, the R2010 or the R1440 variant?

A: The R2010 variants reach up to 2010 mm and suit larger structural work; the R1440 variants trade reach for a tighter working envelope on compact fixtures. Payload choice of 6 kg, 8 kg or 12 kg follows the torch package. Final payload, reach and torch interface combinations are confirmed in the supplier's formal technical documentation.

Q: Can one cell weld carbon steel, stainless steel and aluminium?

A: Yes. The MIG/MAG package carries separate low-spatter schedules for each material. For aluminium, a push-pull torch and matching liner are recommended for stable wire feed over longer conduit lengths.

Q: What is included in the turnkey scope of supply?

A: Robot body, KR C5 smallsize-2 controller with teach pendant, MIG/MAG power source and torch feeder, welding torch with wrist cable routing, and the positioner or fixture agreed in the contract. Options such as vision systems, torch cleaning devices and safety packages are quoted separately.

Q: How long is the lead time?

A: Lead time is 60 days for one set. For multiple sets the delivery schedule is negotiated against the selected configuration and fixture scope.

Q: How is the cell priced?

A: Published tiered list prices are USD 23,000 per set for 1 to 4 sets, USD 22,000 for 5 to 9 sets and USD 21,000 for 10 sets and above. Freight, duties, taxes, installation, commissioning and options are excluded, and the formal written quotation prevails.

Q: What support and warranty come with the workstation?

A: A 1-year warranty with online technical support, a machinery test report, a video outgoing inspection, a pre-production sample before mass production and a final inspection before shipment. Cell integration, fixture design, cycle planning and weld schedule setup are handled with the order.
