Fronius has launched the Robacta Drive TPS/I, a compact, push-pull robot welding torch that features a consistent, modular structure that eases the workload of servicing engineers while simplifying the storage of spare and replacement par ts. Its drive unit dynamic has also been increased to 33 m/s2, which is 10 times that of its predecessor generation.
It is available as a gas-cooled or water-cooled version, and can be fitted to robots capable of supporting just three kilograms thanks to its extra-small interface profile and reduced weight.
It comprises a three-phase stepper motor, a maintenancefree unit for smooth wire travel at a speed of up to 25m/min. Speed is kept constant by an integrated rotary position encoder, while two driven feed rollers transfer the speed to the wire electrode.
