	CHW-50C3 Solid Wire for MAG/MIG Welding	AWS 5.18 ER70S-3 BS EN ISO 14341-A-G 38 4 M G2Si1 BS EN ISO 14341-B-G 49A 2 C G3 CSA W48-01 ER49S-3 JIS Z3312 YGW16 GB/T 8110 ER50-3

Description: CHW-50C3 is a coppered solid wire for welding with mixture gas Ar+CO2. It shows a very good welding performance especially in the range of lower current in case spark is much lower than CHW-50C6SM (ER70S-6). Molten steel flows smoothly and weld seam has a high crack-resistance. It is suitable for butt or fillet structures made by mild steels and 500MPa tensile strength low alloy steels, in particular for high speed welding sheet-steel, e.g. automobiles, railway wagons, vehicles and locomotives.
