Abstract
Guidelines are given for applying SCR's in resistance welding controls. The stresses the SCR's are subjected to in resistance welding applications due to the cyclic nature of the load are discussed from a device, design, and application point of view. In addition the special rating of SCR's and cooling requirements for cyclic duty are described along with techniques for protecting the devices from overvoltage, overcurrent, and loss of coolant. Gating requirements are outlined from a circuit view point.Keywords
