CHW-50C3

CHW-50C3 is a coppered solid wire for welding with Ar+CO2 gas mixtures. It shows a very good welding performance performance especially in the range of lower current. Molten steel flows smoothly and weld seam has a high crack-risistance. It is suitable for butt of fillet strucures made of mild steel and 500Mpa high tensile steel, in particular for high speed welding sheet-steel.
