    Abstract - (Show below) - (Hide below)

    Specifies the requirements for the design, performance and rating of arc welding power sources of the transformer type. It covers transformer type power sources having an alternating current or direct current (rectified) output. Both single-operator and multi-operator machines are covered and calculations of equivalent loadings for multi-operator machines are included. Various routine and type tests are contained in the appendices.

    Scope - (Show below) - (Hide below)

    This standard specifies requirements for the design, performance and rating of electric arc welding power sources (hereinafter referred to as 'welding power sources') with either-(a) transformers-for alternating current welding; or (b) transformer-rectifier units-for direct current, or alternating current/direct current, welding. This standard does not include requirements for connected equipment such as welding leads, electrode holders and automatic wire feeders, etc.
