F120-Z and F160-Z - Weld Pincers for Automation

Thanks to their floating bearing with locking cylinder and their excellent follow-up properties the F-series weld pincers are designed for a wide range of resitance welding applications. Maximum reliability and ease of maintenance generate an outstanding cost of ownership and a very long product life in operation. The weld pincer F-series is designed for welding of materials which require precise and reliable welds continuously. Both weld pincer types deliver outstanding weld process stability and consistent repoducibility.
The F120-Z and F160-Z weld pincers are designed to be used in combination with a variety of electrodes, force sensors and displacement sensors.

Key Features:

• Modular for easy integration for automation
• Adjustable force-firing from 1.2 N to 550N
• Pneumatic actuation
• Optional horizontal mounting
• Ideal for safety critical applications
