Great product, runs smoothly, quick change design with no strings to cut, makes work a pleasure. Long lasting, durable, slag appears to be easily removed from the tip without the slightest bit of dipping. So far I've run about 5 pounds of .035 flux cored wire through a tip of my Esab EMP 215ic and it's still working fine. This system is new to me as I am used to running Lincoln and Miller. So far I am very happy with this system.
