(2) As the wire feeding is smoothly, it can be applied for stable welding. (3) Unique reforming devices such as wire straightener are not necessary for CS-PACK. (4) Since a great amount of wire is contained than spool-wound types, there is less need to change wires, ensuring improved efficiency in large welding jobs. 233
