Abstract

Scope: While resistance welding machines vary considerably in size and complexity, there are basic principles applicable to the installation, operation, maintenance, and troubleshooting. This document is intended to provide basic information to the users of the resistance welding equipment to supplement the instructions and recommendations of the equipment manufacturer. Where there is conflict, the equipment manufacturers’ document shall take precedence. Although this guide is not written with mandatory requirements, mandatory language, such as the use of “shall,” will be found in those portions of the document where failure to follow the instructions or procedures could produce inferior, misleading, or unsafe results. It is the responsibility of the resistance welding equipment user to ensure the equipment conforms to relevant electrical, mechanical, and operating safety standards. Further assistance relating to interpretation or applicability of any of the suggestions outlined in this guide shall be obtained from the original machine manufacturer, rebuilder, integrator, other organization or individual qualified to make such a determination.
