METRIC NUT WELDING ELECTRODES AND COATED PINS
Production Engineering now stocks the coated dolphin nose style pin used in many resistance welding systems. Our DLC (Dimond like coating) pins will outlast your current tool steel pins guaranteed. Choose from the components below or ask us about producing a custom pin for your application. From our standard style pins to our Arctic, that produces higher quality welds and longer life, you can select the product that best meets your needs.
Electrode Heads are made from RWMA class 2 material that are an optimal cost consumable. Class 3 and 10W GH electrodes 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.
Resistance welding 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. We can even help design pins for special applications.
Please Note : Locating pins for projection welding nuts are produced from several different materials with several different coatings. Ceramic, ACT, Tool Steel, DLC, and KCF are available with many sizes in stock. Let one of our knowledgeable customer service representatives help you choose which coating is best for your application.
