WS-5
The WELDERSTAL WS-5 is a ready-to-work cobot built on the bare Fairino FR5 cobot arm (5 kg payload, 922 mm reach, ±0.02 mm repeatability, 6 axes). A versatile base for light production tasks: welding, placing and handling parts. The WS model adds the tool, equipment, Welderstal plugins, configuration, commissioning, training and support.

The WELDERSTAL WS-5 is a ready-to-work cobot built on the bare Fairino FR5 cobot arm. The FR5 arm on its own is a technical base with 5 kg payload, 922 mm reach, ±0.02 mm repeatability and 6 axes. It is a versatile base for light production tasks.
The bare FR5 arm vs the WS-5 cobot
The WS model adds to the arm: the working tool (torch, gripper or holder), cell equipment, Welderstal plugins, process configuration, safety assessment, commissioning, operator training and support after start-up.
Selection and deployment
We select the model after analysing the process - the part, tool, fixturing, cycle time and space at the cell. Start with a process description. See also ready-made cobot kits, all WS cobots, welding cobots and the WS-3 and WS-10 models.
What you buy
What the WELDERSTAL WS-5 kit includes
You are not buying just the Fairino FR5 cobot arm. Our specialists analyse the cell and put together the complete WS cobot - from the tool and plugins to commissioning, training and support after start-up.
Technical base
The WELDERSTAL WS-5 cobot is built on the Fairino FR5 arm - 5 kg payload, 922 mm reach.

02 
Magnetic foot
Quick mounting of the cobot on a steel table or part. With longer arms the PIN 28 system is used instead.
03 
Teach pendant
Touch control panel with an emergency button for programming and operating the cobot.
04 
Manual 7th axis
Torch angle adjustment from -60° to +60° without reprogramming the path. Matched to the weld in a few seconds.
05 
Smart tool
A wrist-mounted handle with buttons. The operator saves points and starts the program without reaching for the pendant.
06 
Welderstal plugin (Polish/English)
Weld sequences, points and arc parameters in the operator’s language. The code is generated in the background.
07
Process configuration
Paths, parameters and working logic set up for your part, product and cell pace.
08
Operator training
Operation, changeovers and programming new parts. The operator works independently from day one.
09
Support after start-up
Technical contact, materials, the forum and help with further parts.
Applications
What we select the WELDERSTAL WS-5 for
The most common tasks this cobot handles well. We confirm the final scope after a process analysis.
Placing and handling parts
Light pick-and-place operations between stations and placing parts into packaging once the gripper is matched to the product.
Light production tasks
Simple, repeatable auxiliary operations where a steady pace and repeatable motion matter more than manual work.
Welderstal plugins
The WELDERSTAL WS-5 with Welderstal plugins
Plugins are the difference between a bare arm and a ready-made cell. The operator works with prepared points and parameters, and a changeover does not start with programming from scratch.

Accessories
Choose accessories for the WELDERSTAL WS-5
We match equipment to the process: welding torch holders and torches, grippers, suction cups, fixtures, tables and positioners. Accessories are selected together with the model, not separately.

Kits the WELDERSTAL WS-5 works in
A cobot is an arm with equipment, ready to work. A kit goes a step further: it adds a process tool, an external axis or line equipment and becomes a complete cell.
Safety
We assess safety for the whole cell
The Fairino FR arm is a collaborative robot - it has joint sensors and force limiting. Whether the cell can work without guarding, however, depends on assessing the whole: tool, part, speed, forces and surroundings. We carry out this assessment before commissioning.

Each WS cobot is built on a different Fairino FR arm - they differ in payload and reach.
FAQ
Frequently asked questions
How does the WS-5 differ from the bare Fairino FR5 arm?
The FR5 is the cobot arm alone, with 5 kg payload and 922 mm reach. The WS-5 is a Welderstal cobot built on that base: the FR5 arm, tool, equipment, plugins, configuration, commissioning, training and support. You can find the FR cobot arms on the Fairino models page.
What tasks is the WS-5 suitable for?
The WS-5 is a versatile base for light tasks: MIG/MAG and TIG welding of repeatable parts, placing and handling components, and simple production operations. We select the specific scope after analysing the process and tool.
Is the WS-5 suitable for welding?
Yes, the FR5 is often chosen as the base of a welding cell. Its ±0.02 mm repeatability helps keep welds consistent on repeatable parts. The WS model adds the torch, equipment, welding plugin and operator training.
How do we select and deploy the WS-5?
We start with a description of the process, part and cell. We check whether the task suits a cobot, select the tool and equipment, configure the cell with plugins, commission it and train the operators, and after start-up we agree the scope of support.
