Arc Welding and Cutting - Installation |
||||||
|
Arc welding requires proper installation of equipment. A critical part of
installation is ensuring that proper grounding is completed. The frame or case of the
welding machine (except engine-driven machines) shall be grounded under the conditions and
according to the methods prescribed in Subpart S, Electrical. Conduits containing electrical conductors shall not be used for completing a work-lead circuit. Pipelines shall not be used as a permanent part of a work-lead circuit, but may be used during construction, extension, or repair providing current is not carried through threaded joints, flanged bolted joints, or caulked joints and that special precautions are used to avoid sparking at connection of the work-lead cable. |
