IEC 60974-6:20 15规定了适用于设计供外行人使用的有限责任弧焊和切割电源和辅助设备的安全和性能要求。电动设备旨在连接到单相公共低压供电系统。发动机驱动电源的输出功率不能超过7.5 kVA。这第三版取消并取代了2010年出版的第二版。它构成技术修订。与上一版相比，主要的重大技术变化如下: -修改的测量条件（见7.3.1）； -根据绝缘等级改进温度极限值（见表1）； -改进的最高温度限制(见表2)； -删除过载测试。 本出版物应与IEC 60974-1:20 12一起阅读。

IEC 60974-6:2015 specifies safety and performance requirements applicable to limited duty arc welding and cutting power sources and auxiliaries designed for use by laymen. Electrically powered equipment is intended to be connected to the single phase public low-voltage supply system. Engine driven power sources cannot exceed output power of 7,5 kVA. This third edition cancels and replaces the second edition published in 2010. It constitutes a technical revision. The main significant technical changes with respect to the previous edition are the following:
- modified measurement conditions (see 7.3.1);
- improved values for temperature limits according to the class of insulation (see Table 1);
- improved maximum temperature limits (see Table 2);
- deleted overload test.

This publication is to be read in conjunction with IEC 60974-1:2012.
