Anyone have experience with large capacity (nameplate 400A, 380 volt) spot welders and the best procedure to use in combating voltage drop in the building wiring system causing lighting etc to dim? These welders are only activated for very short periods but cause havoc in the rest of the building. My first suggestion to the customer would be oversized conductors but would like to hear from the rest of you should somebody have a clear and dependable way to solve this problem. Customer is building a new factory and would like to eliminate this problem at the start. Thanks in advance for any suggestions.
