1, JG-50 is China's Jinzhou Jintai welding wire factory produced wire.2 and 50 represent the tensile strength of the welding wire 490N/mm2, that is, we usually say that the tensile strength is about 50 kilograms.3, 50, there are 52, 53, 80 and so on.4, JG50 TIG is a non welding wire is used for welding melt gas arc welding (i.e. argon arc welding).5, then JG50 is argon arc welding wire, understand?
