TPS/i Robotics – Automated Welding Redefined.

Fronius is launching the new TPS/i Robotics power source, which is specially designed to meet thedemands of robot-assisted welding. Thanks to its interconnected and fully synchronised systemcomponents, it enables robotic welding to be performed faster and with a higher degree ofreproducibility. A new level of quality can be achieved and maintained as a result of the ingenious yeteasy-to-use functions of the TPS/i Robotics.


Fronius engineers have drawn on the power source's consistently implemented digital system architecture andnew communication technology features to cover and address all the major influencing factors crucial to thewelding process with high definition and reaction speed. The result is an exceptionally stable arc and optimumwelding results.

A crucial role is played by the modified dip transfer arc (LSC – Low Spatter Control) and the modified pulsed arc(PMC – Pulse Multi Control), which give the welder a significantly higher level of control over the arc. The useris also supported by brand new stabilisers: while the penetration stabilizer ensures that the penetration remainsconstant – even if stick out fluctuations occur – by adjusting the highly dynamic wirefeeder, the arc lengthstabilizer keeps the arc at an optimum length when the arc geometry (e.g. due to a change in the weld seamprofile) or weld pool temperature changes.

As a result TPS/i Robotics not only makes the welding process considerably quicker than ever before, but alsoenhances the weld seam quality. One of the visible improvements is the minimal amount of spatter produced.

Another benefit of the power source's consistent digitalisation is the continuous collection of information on thecurrent status of the power source and on every weld seam, which is made available to the user. This detaileddata can be used to monitor, analyse and document the welding process. Using the central server unit(WeldCube), the data gathered from several power sources via their Ethernet interfaces can be combined andmanaged from a company-wide perspective.

Fronius is also forging new paths in the area of communication between the welding system and robot control.Like all other process control components, the TPS/i system's new robot interfaces are incorporated into thesystem bus architecture and are therefore able to provide data relevant to the robot control in real time.

A new Interface Designer allows the robot interface to be programmed quickly and conveniently offline using agraphical user interface. Users can thus configure and adapt the interface to their own individual requirementsat any time. In addition, Fronius provides pre-prepared interfaces to the control systems of leading robotmanufacturers.
