Tuffaloy Weld Pins
METRIC NUT ELECTRODES
TUFFALOY now stocks the head/pin style welding system components that adds to your selection of stud and nut welding needs. From our standard style to our Arctic electrode that produces higher quality welds and longer life, you can find the product that best meets your needs with us.
Heads are made from RWMA class 2 material that are an optimal cost consumable. Class 3 and 10W are available for longer life. With a concave seat the pin locates in the center of assembly when air is applied to the system. This gives you a repeatable location for automated nut feeders to introduce the nut to the environment.
Pins have a nonconductive surface on a steel matrix that gives longer life in a repetitive motion environment. With the threaded head securing the pin in place it makes it easy to replace the pin to meet your requirements. TUFFALOY can design pins for special applications.
