Power supply for resistance — Welding machines — III

An adequate power supply is one of the requisites of present-day, high-production resistance welding. A major part of the power supply system of any industrial plant lies within the plant itself and consists of the plant wiring and transformer substations. It is the purpose of this report to show how to properly lay out such a plant distribution system for serving welders. Much of the fundamental data included in the tables and charts is not new but is included in order that the layout engineer will have complete information available in one compact report and will not have to refer to various articles and handbooks, copies of which may not be readily available.
