WELDERSTAL
WS-3 WMS
The WELDERSTAL WS-3 WMS is a ready-to-work welding cobot built on the bare Fairino FR3-WMS arm (3 kg payload, 622 mm reach, ±0.02 mm repeatability, 6 axes). It is the most compact welding variant in the family - easy to move between workstations. The WS model adds the torch, cell equipment, the Welderstal welding plugin, configuration, commissioning, training and support.

The WELDERSTAL WS-3 WMS is a ready-to-work welding cobot built on the bare Fairino FR3-WMS arm. The FR3-WMS arm on its own is a technical base with 3 kg payload, 622 mm reach, ±0.02 mm repeatability and 6 axes. It is the most compact welding variant in the FR family.
The bare FR3-WMS arm vs the WS-3 WMS cobot
The WS model adds to the arm: the torch and welding equipment, part fixturing, the Welderstal welding plugin, 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, weld, fixture, cycle time and space at the cell. Start with a process description. See also ready-made cobot kits, all WS cobots and the WS-3 WML and WS-5 WML variants.
What you buy
What the WELDERSTAL WS-3 WMS kit includes
You are not buying just the Fairino FR3-WMS 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-3 WMS cobot is built on the Fairino FR3-WMS arm - 3 kg payload, 622 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-3 WMS for
The most common tasks this cobot handles well. We confirm the final scope after a process analysis.
Changing welding workstations
The lightest welding variant in the family. Suitable where the cobot is moved between stations instead of staying in one place.
Starting welding automation from scratch
A compact base for a first robotic cell: operator training, process trials and the move from manual welding to a repeatable process.
Welderstal plugins
The WELDERSTAL WS-3 WMS 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-3 WMS
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-3 WMS 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.

Other WS cobots
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-3 WMS differ from the bare Fairino FR3-WMS arm?
The FR3-WMS is the cobot arm alone in its welding variant, with 3 kg payload and 622 mm reach. The WS-3 WMS is a ready Welderstal cell built on that base: the FR3-WMS arm, torch, equipment, welding plugin, process configuration, commissioning, training and support after start-up.
How does the WS-3 WMS differ from the WS-3 WML?
The difference is arm reach. The WS-3 WMS has 622 mm and ±0.02 mm repeatability, the WS-3 WML has 922 mm and ±0.05 mm. Both have a 3 kg payload and the rest of the kit is the same. We choose the WMS for smaller parts and tight cells, the WML for larger structures.
What parts is the WS-3 WMS suitable for?
Parts that fit within the 622 mm reach and do not require more than 3 kg payload including the torch and cables. We confirm the specific range after analysing the part, fixture and cycle time.
What is added to the arm in a WS kit?
The torch and welding equipment, part fixturing, the cell base, the Welderstal welding plugin (Polish/English), process configuration, cell safety assessment, commissioning, operator training and technical support after start-up.
