Review on Weld-Aid-7061 Lube-Matic Wire Kleener Pad, Red (Pack of 6) - Enhance Welding Performance with This Innovative Wire Cleaning Solution by Nathan Tsugawa

Works, best price I could find. Good business. It keeps the inside of your MIG gun mounting liner clean. Cleans the wire itself of contamination BEFORE it enters the MIG liner. Improves and extends the life of the liner itself. Along with reducing "skipping" (to a degree) of the case's internal "wire resistance" due to dirt and debris. This may not be noticeable to an inexperienced welder, but improves the overall quality of the weld over the long term. And reduces the number of liners you will purchase over the life of the machine. Change the oil in your car for the same reason. Good service. Easy.
