IEC 60974-6:20 10规定了适用于有限负荷弧焊和切割电源以及设计供外行人使用的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。这第二版取消并取代了2003年出版的第一版。它构成技术修订。与上一版相比，主要的重大技术变化如下: -范围的扩展； -修订标题； -故障条件下的触摸电流（见6.3.7）； -基于两个独立设备的热要求的新定义，一个用于热保护，一个用于热控制（见7.1）；-20℃下热性能的新定义（见7.2）； -热安全要求基于正常条件下的工作温度和过载条件下的最高温度（见7.4）； -增加热控装置异常运行试验（见10.4）； -对辅助设备的新要求（见第16条）； -新的评级板定义（见第17条）； -引入新的强制性警告符号（见12.1.11 7.3，方框17b）和19.2）； -由于IEC 60974-1:20 05的发布而引起的变化。 本出版物应与IEC 60974-1:20 05一起阅读。

IEC 60974-6:2010 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 can not exceed output power of 7,5 kVA. This second edition cancels and replaces the first edition published in 2003. It constitutes a technical revision. The main significant technical changes with respect to the previous edition are the following:
- extension of the scope;
- amendment of the title;
- touch current at fault condition (see 6.3.7);
- new definition of thermal requirements based two independent devices, one for thermal protection and one for thermal control (see 7.1);
- new definition for thermal performances at 20 °C (see 7.2);
- thermal safety requirements are based on operating temperature for normal condition and maximum temperature in overload condition (see 7.4);
- addition of abnormal operation test for thermal control device (see 10.4);
- new requirement for auxiliaries (see Clause 16);
- new rating plate definition (see Clause 17);
- introduction of new mandatory warning symbols (see 12.1.117.3, Box 17b) and 19.2);
- induced changes due to publication of IEC 60974-1:2005.

This publication is to be read in conjunction with IEC 60974-1:2005.
