Spot welding for indoor products and 6-axis welding robots for sustainable quality of IP protection.

The use of robotic technology allows for precise and quick results, less waste, and greater safety. The robots are capable of reaching otherwise inaccessible locations and can perform complicated and precise weld lines and welds more quickly than in manual welding. This frees time for manufacturing and allows for more flexibility.

 Welding robots with integrated torch cable system. Arc sensors detect deviation of welding current.
