AWS F4.2:2020 pdf download.Safety Guidelines for Proper Selection of Welding Cables
1.1 Scope.
This safety standard offers guidance in the proper selection and use of welding cables, an important aspect of the safe setup and use of welding equipment. It promotes workplace safety for welders and associated personnel by giving educators, operators, managers, and supervisors information about the testing, selection, and safe use of welding cables. Proper cable selection also improves machine efficiency and reduces energy use. The purpose of this standard is to provide reasonable and adequate means, ways, and methods for the testing, selection, and safe use of welding cables.
This standard recommends minimal performance requirements for welding cables in the tests herein described. It is not intended to imply quality of nonelectrical performance or of other factors of design, such as insulation/jacket perfor-mance, service life or cable appearance, except as indicated by the tests called out. Nor should these recommendations be interpreted to mean that the welding cables described herein are capable of affording greater protection than is indi-cated in this standard.
1.2 Units of Measure. This standard makes sole use of U.S. Customary Units. Approximate mathematical equivalents in the International System of Units (SI) are provided for comparison in parentheses or in appropriate columns in tables and figures.
Work performed in accordance with this standard may involve the use of materials that have been deemed hazardous,and may involve operations or equipment that may cause injury or death. This standard does not purport to address all safety and health risks that may be encountered. The user of this standard should establish an appropriate safety program to address such risks as well as to meet applicable regulatory requirements. ANSI Z49.1 should be considered when developing the safety program.
2. Normative References
The following documents are referenced within this publication and are mandatory to the extent specified herein. For undated references, the latest edition of the referenced standard shall apply. For dated references, subsequent amend-ments to, or revisions of, any of these publications do not apply.
5. Wire Gauge System
Depending upon the country of use, the physical size of cables, including insulation and copper content, used for weld-ing will follow a locally accepted gauge system. The American Wire Gauge (AWG) system and SAE, both generally accepted in the United States, are referenced in welding cable comparison charts for purposes of this standard. The met-ric system, generally preferred in Europe and Asia, is also referenced in comparison charts for the purpose of this stan-dard. Table Al, in Annex A, compares several systems in use today.AWS F4.2 pdf download.
