Had to pack in a mig welding course today. All I could see when welding was the green weld line not the line that I was supposed to be welding on. I was using an auto darkening helmet.
Maybe the setting on the helmet was set to the darkest. I set my helmet when using my welder at work to shade 10.5-11...some use it darker but i struggle as you did.Everyones eyes are different so try out again?No I didn't take a note of the helmet brand. I wonder if a lot of the light from the welding process was being lost as it was reflected from the shiny metal surfaces of the part that I was trying to weld and the table. I achieved much straighter weld lines on dull scrap metal.
