When this configuration makes sense
- ✓Repeatable batches of parts with torch access to the weld
- ✓Companies that want to use a compatible MAG power source

Applications
When the part is repeatable and the torch has access
The base variant works well for batches that can be fixtured securely and handled within the arm’s working area. It needs no track or part rotation, provided the torch can reach the whole weld in a properly designed cell.
When to choose a different solution
- -Processes without repeatable part fixturing
- -Tasks requiring an additional axis: a linear track or part rotation
- -Laser processes - use the laser welding kit for those
The key limitation
No arm can replace secure fixturing or create torch access where there is none. Long parts and circumferential welds need an additional axis - a linear track or a positioner.
Scope of delivery
A kit is more than the arm alone
The photo shows the cell at work: the cobot guides the torch along a programmed path. The kit consists of the five components shown on the board at the top of the page - the arm, smart tool, manual seventh axis for torch adjustment, MIG/MAG torch with a Euro connector and the cobot base. The magnetic foot applies to the variant with the WS-5 arm; the kit with the WS-5 WML works on the PIN 28 system. The lists below separate the scope of delivery from what we select for the cell.
Included in the kit
- ✓WS cobot arm matched to the process - with power supply, safety button and control box
- ✓Cobot base matched to the arm: PIN 28 system in the WS-5 WML kit, magnetic foot or PIN 28 in the WS-5 kit
- ✓Smart tool, manual seventh axis and adjustable torch holder
- ✓5 m MIG/MAG cable, control panel and Welderstal welding plugin (PL/EN)
- ✓Delivery, commissioning, operator training and certification appropriate to the cell
- ✓5 years of technical support included in the kit price
Selected for the process
- -MAG power source - your own or selected by Welderstal
- -Part fixtures and additional safeguards are selected for the process
- -Welding table with a hole grid for the PIN 28 system, if the cell is to be relocated
Choosing the cobot
Which cobot goes into the kit
Any cobot in the WS family fits the welding kit. We match the model to the part, reach and cycle time - the rest of the kit stays the same.

MIG/MAG integration
You can use the welder you already have
The base variant does not include a MIG/MAG power source. We check whether your welder can be connected via a Euro connector, or we select a suitable power source separately.
- MIG/MAG power source
- WS-5 WML control
- Cobot and torch
- Part and weld
- On the kit side
- 5 m MIG/MAG cable, torch holder, control panel and the Welderstal welding plugin in Polish and English.
- On the qualification side
- Power source compatibility, process parameters, torch geometry and the way the part is fixtured - we check these before selection.
Cell base
The cobot base depends on the chosen arm
The cobot has to return to the same position relative to the part. The longer the arm, the greater the moment on the base - which is why the mounting method in the kit is not arbitrary.
Kit with the WS-5 WML: PIN 28 system
With a 1900 mm reach, a magnetic foot cannot hold the cell base. That is why we supply the WS-5 WML kit on PIN 28 locating pins. After repositioning, the cobot returns to the same base and the program needs fewer corrections.
Magnetic foot: WS-3 and WS-5 only
Only the short arms - the WS-3 and WS-5 - work on the compact magnetic foot. It attaches to a steel surface without tools, so it is the choice for cells moved between workplaces. A larger cobot needs a PIN 28 base.
Kit selection
Five kits, five different jobs
The welding kits share the same plugin and the same choice of arm. What sets them apart is the external axis and the joining process. The choice depends on the part geometry, not on the arm’s reach alone.
| Kit | When it makes sense | External axis |
|---|---|---|
| Basic kitYou are here | Repeatable parts that fit within the arm’s working envelope. | No additional axis |
| WS kit + linear track | Long structures or several workstations in one line. | External 2 m linear axis |
| WS kit + positioner | Circumferential welds on pipes, sleeves and shafts. | External rotary axis |
| Laser welding kit | A process qualified for laser: welding, cleaning or cutting. | Separate architecture and training |
| Palletising kit | Stacking cartons, bags and containers from the end of the line onto a pallet. | Column-mounted cobot, guarding and conveyor |
From trial to production
Process first, configuration second
We do not select a kit from the catalogue alone. The order is the reverse: first we check the part and the process, and only then the cell configuration.
- 01
Part and process
We check the geometry, weld, material, fixturing, cycle time and available space.
- 02
Welding trial
We set the path, torch position and the way the cell works with the MIG/MAG power source.
- 03
Cell
We prepare the configuration, assembly, calibration and commissioning on the customer’s site.
- 04
Operator
We train staff to operate the cell and provide five years of technical support.
FAQ
Questions about the basic kit
Which cobot goes into this kit - WS-5 WML or WS-5?
Your choice. The WS-5 WML is based on the Fairino FR5-WML arm with 1900 mm reach and ±0.1 mm repeatability. The WS-5 is based on the FR5: 922 mm and ±0.02 mm. The rest of the kit is the same, and we match the arm to the part size and required accuracy.
How does the cobot mounting differ between the two versions?
We supply the WS-5 WML kit on PIN 28 locating pins. With a 1900 mm reach a magnetic foot cannot hold the cell base, so it is not used in this version. The WS-5 kit can work on a magnetic foot or on the PIN 28 system.
Does the kit include commissioning and training?
Yes. The scope covers preparing and commissioning the kit, operator training, certification appropriate to the cell and 5 years of technical support included in the kit price.
Does the kit include a MAG welder?
Not in the basic version. The cell is ready to integrate with the customer’s power source via a Euro connector or with a power source selected by Welderstal.
