TUFF Threaded Base
Tuffaloy’s TUFF BASE series of electrode holders are designed for use with GH Head style weld heads. The TUFF BASE can be used in both Nut and Stud welding applications. The Threaded Taper mount design is allows you to mount the TUFF bases to any standard press welder or rocker arm welder with platen mount holders or custom tooling.
The benefits of the TUFF BASE series are:
- Water cooling channels to cool the weld head and extend electrode life
- Inlet airport for blowing air through the part to prevent slag build up
- Low Maintenance design
The TUFF Threaded base includes a return spring and a cup for holding a weld pin. EVOLUTIONTM GH Heads and SS Weld Pins are sold separately.
