CWR electrostatic oiler was designed to lubricant the welding wire with AL 503 coating material. CWR Electrostatic oiler provides a layer of lubricant over the surface of the wire. The resulting wire has an improved appearance, will not clog the automatic welding apparatus, and the lubricant will not contribute adversely to weld porosity in use. Al-503 welding lubricant won't increase the smoke amount during welding process.
