Selection of Fuses for Resistance Welding Machines

This paper covers: 1. An analysis of available fuse data with special reference to the data´s applicability for resistance welding machines. 2. A proposed method of analysis of fuse characteristics. 3. Discussion of these fuse characteristics. 4. Use of these characteristics in welding applications. 5. The application of fuses as it is practiced in the industry today. The data that are presented are based only on 250-volt fuses. Six-hundred-volt fuses were checked and found to have characteristics substantially the same as 250-volt fuses. Consequently, any system of rating of 250-volt fuses applies also to other fuses.
