Weld-Aid Lube-Matic® Pad system will clean and lubricate your wire to extend tip and liner life by up to 300% while preventing burnbacks. Simply install both red and black pads right before the inlet guides with the red pad closest to the welding wire. The wire is cleaned as it travels through the red pad, then the black pad adds just a touch of lubricant to help the wire move through the liner and tip. The Lube-Matic® Pads are also available in separate bulk packages and are part the complete line of Weld-Aid products engineered to improve your welding productivity. crcindustries.com weldaid.com
