RG4509336

• A copper coated, low carbon steel rod which is widely used on mild steel, it offers good ductility and machinability.
• Use a neutral flame; however a very slight excess of acetylene assures the absence of an oxidizing flame which adversely influences weld quality.
• Flux is not needed but "puddling" of the molten weld metal will bring any scale or impurities to the surface.
