I'm by no means a professional welder but I follow a lot of welders on IG. They seem to have started recommending this Lizer tungsten to everyone. I was intrigued, but I still have a full box of 2% Lanthanate. I was never happy with how wide and messy my wires were no matter how sharpened the tungsten was. I finally broke down and tried the Laizre and I was blown away! Either I have a very bad batch of 2% or Lyzr is the best tungsten money can buy right now. You have to do it yourself to try it.
