适用范围：This standard is applicable to welding power sources for manual metal are wel-ding with limited duty with covered stick electrodes.These welding power sourcesa) are limited to a rated maximum welding current of 160 A,b) are fUted with a thermal cut-out device,c) have performance based on the number of reference electrodes, capable of being melted with the welding power source in the cold and hot state andd) carry on their rating plate a declaration of the fuse size necessary for the maximum output.This standard is not applicable to rotating welding power sources or welding power sources with remote control or welding power sources incorporating fre-quency conversion.Note.- Inverter type welding power sources are excluded from this standard on the grounds thata) there are not yet available methods to test the safety of themb) they cause considerable harmonic distortions to the supply.
