HD Non-Piloted-Nut Electrodes
Tuffaloy Heavy Duty Non-Piloted-Nut Electrodes have a spring-loaded pin so they can't interfere with the contacting of nut and sheet under welding pressure. The parts have an optional 10W weld face to improve the electrode life.
The Heavy Duty Non-Piloted Electrodes are designed for use with Tuffaloy's Heavy Duty Stud-Nut Holders which are suitable for high forces used for projection welding.
The parts have a large diameter taper available in two sizes:
- HD Size 1 with a 1.00 IN diameter weld face
- HD Size 2 with a 1.50 IN diameter weld face
