DW-50 u in• Fast freezing slag formula gives DW-50

• e its excellent weldability not only inhorizontal but in vertical and overhead

t welding.

• DW-50 can be used with 100%C02 or75%Ar-25%C02 shielding gas. It has awide welding parameter range whichmakes DW-50 very versatile.

• Its low fume emission formula creates aclean welding environment at anywelding condition.

• Non-baked wire surface covered withspecial lubricant creates smooth wirefeedabilty and extended liner life.
