Review on Hobart 770028 Welding Holder Electrode: Superior Performance for Precise Welding by Gilbert Pfaff

This is a great tip and very pleasant to use. It even has a little lip on the bottom to attach it to something so it doesn't touch metal and accidentally start an arc. My only complaint is that after all day of unscrewing and unscrewing to install new bars, I think the wiring loosened and fell out and I had to turn the machine off and plug it back in. I've made sure it's screwed in as tight as possible and haven't had any problems so far. The time will show.
