scope:

This part of IEC 60974 specifies safety and performance requirements for gas consoles intended to be used with combustible gases or oxygen. These gas consoles are designed to supply gases for use in arc welding, plasma cutting, gouging and allied processes in non-explosive atmospheres.

The gas console can be external or internal to the power source enclosure. In the latter case, this standard also applies to the power source.

1DV.1 Modify clause 1 by adding the following:

This part of IEC 60974 does not include gas consoles intended for use in hazardous locations (i.e., explosive atmospheres) as defined in ANSI/UL 60079 and in Article 500 of ANSI/NFPA 70.

NOTE The placement of an ANSI/NEMA/IEC 60974-8-compliant gas console in a location is not intended to change the classification of that location.
