Stillwater's introduction to automatic tip dressers began in 1987 at the urging of a major automobile manufacturer who was unable to purchase a tip dresser that met their requirements. Stillwater developed a dresser that met and exceeded all of our customer's criteria.
Today, with thousands in use on both sides of the Atlantic, Stillwater offers a full range of dressers, cutters and accessories.
Why Tip Dress?
During the resistance welding process the welding electrodes are exposed to severe heat and pressure. In time, these factors (heat and pressure) begin to deform the electrodes. Welding today's coated materials also tends to contaminate the face of the electrodes. As the electrode deforms, the weld controller is called upon to "step" up the welding current in order to generate an acceptable nugget. Eventually, the line will have to be shut down in order to replace the electrodes or to manually go in and hand dress the electrodes. This process will improve the weld cycle but in either case, the line is stopped and time is lost.
