01Services
From the first program to series production
- 01
Commissioning
Programming and start-up of new cells and lines at the customer's plant, through to handover to production.
- 02
Offline programming and simulation
Paths, reach, interference and cycle times validated before arriving at the plant.
- 03
Modifications and cycle-time optimisation
New part variants, tooling changes and cycle-time reduction on lines already in production.
- 04
Production support
On-site or remote technical assistance to resolve stoppages, weld defects and adjustments.
- 05
Robot-PLC integration
Signals, communications, sequences and safety between robots, PLCs and cell peripherals.
02Process
How a project runs
- 0
Analysis
Review of layout, scope, robot and PLC brands, and installation timeline.
- 1
Offline programming
Simulation of paths, reach and cycle time before arriving at the plant.
- 2
Commissioning
Programming, spot and seam tuning, and line testing on site.
- 3
Production ramp-up
Support until target cycle time and weld quality are reached.
- 4
Support
Follow-up assistance, modifications and new part variants.
03Specialty
Robotic welding for automotive
The quality of a seam or a spot depends as much on the program as on the process. We know both.
Resistance spot welding
Spot welding with servo and pneumatic guns: spot programs, equalisation and quality control.
Laser welding
High-density laser welding lines, where path accuracy is critical.
04Technology
Every brand, one standard of work
We program to whatever standard each customer requires, so their maintenance team can follow the program the day after handover.

07How we work
Our way of working
- 01
Willing to travel
We work on site during commissioning and production ramp-up, in Spain or abroad.
- 02
Customer standards
We work to whichever programming standard each customer and plant requires, with clean, documented programs.
- 03
Weld quality
A good part is the goal, not just a moving robot. We care about the process as much as the path.
- 04
Direct contact
Customers deal directly with the people who program, with no intermediaries between the two teams.
- 05
Job management
Planning, follow-up and clear progress reporting through to handover.
