    Abstract - (Show below) - (Hide below)

    Part 2 specifies the requirements for the design, performance and rating of arc welding power sources of the rotary type. It covers rotary type power sources having alternating current and/or direct current generator 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 rotating a.c. and/or d.c. electric arc welding power sources (hereinafter referred to as 'welding power source') consisting of alternators or generators with suitable control for regulating welding current, and driven by electric motors, internal combustion engines or mechanical drives from separate prime movers.This standard does not include requirements for connected equipment such as welding leads, electrode holders and automatic wire feeders, etc.
