Arc welding equipment - Part 7: Torches
IEC 60974-7:2013 specifies safety and construction requirements for torches for arc welding and allied processes. This part of IEC 60974 is applicable to manual, mechanically guided, air-cooled, liquid-cooled, motorized, spool-on and fume extraction torches. In this part of IEC 60974, a torch consists of the torch body, the cable-hose assembly and other components. This part of IEC 60974 is also applicable to a cable-hose assembly connected between a power source and ancillary equipment. This part of IEC 60974 is not applicable to electrode holders for manual metal arc welding or air-arc cutting/gouging. This third edition cancels and replaces the second edition published in 2007 and constitutes a technical revision. The significant changes with respect to the previous edition are listed below: - new requirement for degree of protection of torch coupling device (see Table 1);- scope is extended to cable-hose assembly connected between a power source and ancillary equipment (see Clause 1);- torch parts, as recommended by the manufacturer, are included in the safe plasma cutting system design (see 7.4.2);- new flammability requirement for handle material (see 11.3).This publication is to be read in conjunction with IEC 60974-1:2012.

Arc welding equipment - Part 7: Torches
IEC 60974-7:2019 specifies safety and construction requirements for torches used for arc welding and allied processes. This document is applicable to manual, mechanically guided, air-cooled, liquid-cooled, motorized, spool-on and fume extraction torches. This fourth edition cancels and replaces the third edition published in 2013 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) definitions 3.11 and 3.20 were revised; b) requirements for arc striking and stabilizing voltage rating have been added to the sequence of type tests (see 6.2); c) the AC test voltage requirement for torches that utilize arc striking and stabilizing voltageshas been revised (see 7.5.2); d) the test configuration of isolated circuits for torches that utilize arc striking and stabilizing voltages has been revised (see 7.5.2); e) the metal tube used for the heating tests has additional allowable means of cooling methods (see 8.3.2 and 8.3.5); f) for fume extraction torches, the instructions for use include additional information (see Clause 13, item i)). This document is to be used in conjunction with IEC 60974-1:2017.
