I have used a few Ad hood speedglas,Miller,Hobart,Hb. The one I like best is a old school Fiber-metal with a Auto-lens because I can switch it to a fixed shade and keep right on welding with no down time. I have 2 one with about 2 inchs cut off with a leather flap and one stock. Plus most shops always have 2x4 glass on site where the auto tend to be a Pia to get from your employer. Like most people have said it more about how you act the the hood on your head. Be early, show up ready to work clean work cloths boots for the job welding hats ect. I shine my boots a starch my shirts old school yes but shows you have pride. Have copy's of any paper work you may need burning card. weld cert,OSHA,SWAC card,drivers license.
