标准摘要
[中文适用范围]： 本部分IEC 60974规定了适用于普通人员使用的限制工作制电弧焊和切割电源及辅助设备的性能和安全要求。电力驱动的设备设计用于连接单相公共低压供电系统。驱动式电源的输出功率不得超过7.5 kVA。注1：此类设备通常由住宅区的非专业人员使用。本部分IEC 60974不适用于需要电弧引弧和稳弧装置、液体冷却系统、气体控制台或三相输入供电的弧焊和切割电源，且仅用于工业和专业用途。本部分IEC 60974也不适用于在机械导向应用、埋弧焊工艺、等离子挖削工艺和等离子焊接工艺中使用的弧焊和切割电源及辅助设备和，这些由IEC 60974的其他部分涵盖。注2：为工业和专业用途设计的电源、送丝机、焊炬和焊钳分别由IEC 60974-1、IEC 60974-5、IEC 60974-7和IEC 60974-11覆盖。 [外文原描述]： 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 .
