I was wondering what people had to say about welding hood lens colors and fixed or auto shade. Just recently I had to use a coworkers hood on a job. The lens in his helmet was I guess an amber or brown type color upon striking an arc. I have always owned green shade lenses and wondered what others use. How about auto dark helmets. Are you for or against them. Also what # shades do you prefer for your certain types of welding. I hope to see some good input. Thanks and have nice day.
