F120, F160, FD120 - Spot Welding Heads for Automation
Thanks to their excellent dynamic response and their stable follow-up properties the F series weld heads represent the best solutions for a wide range of resistance welding applications. Maximum reliability and ease of maintenance generate an outstanding cost of ownership and a very long product life in operation. The F120, F160 and FD120 series is designed for welding of materials which require precise and reliable welds continuously. All three weld head types deliver outstanding weld process stability and consistent reproducibility.
The F120, F160 and FD120 weld heads are designed to be used in combination with a variety of electrodes, force sensors and power supplies.
