“We first began using the TPS/i Robotics power sources from Fronius as a pilot customer, but the exceptional results we achieved meant we have stayed ever since.”

Welded components are rapidly growing in importance in the formwork industry. Choosing the appropriate welding technology is not only critical for the quality of the products and the performance of the company, but it can also deliver significant cost savings.

“By turning to the latest welding technology from Fronius, we are making a huge leap forward in terms of system availability, welding speed, weld seam quality and flexibility,” Thomas Auer, Master Welder at Doka.


Doka has optimised its welding processes with technology from the Austrian innovation leader Fronius. By upgrading an existing robotic welding cell with a Fronius TPS/i Robotics power source, Doka has been able to boost productivity while enjoying even greater flexibility. System availability - including setup time - has risen from 90 to 94 percent. The innovative arc length stabiliser of the TPS/i Robotics in conjunction with the new PMC pulsed arc process increases welding speed by up to 10 percent. In order to ensure that any collisions do not damage the welding torch or cause long machine downtimes, Doka has fitted the magnetic Fronius CrashBox. In the event of a collision, this breaks the magnetic connection to the workpiece, protects against mechanical damage and also ensures high levels of machine availability.
