Automatic contact tip changeover in just 40 seconds

Changing the contact tip manually is time-consuming and necessitates an interruption to production. The Robacta CTC automates this step. Changing the tip takes no more than 40 seconds - without a halt in production.

Pre-defined torques also reduce the risk of operating errors by maintenance personnel, thus extending the service life of the equipment.
