I was welding last night for about 30 minutes and I kept getting flashed as the lens switched on and off. I had a 150 watt work light about 12" away from my work piece to see what I was doing. I don't know what was causing the problem but it could have been from the intermittent popping in the MIG wire as I hit rusty or oily metal and lost the arc for a millisecond. I was using a Miller auto darkening welding helmet that's about 3 years old. I have Miller, Hobart auto dark helmets and 6 other fixed shade helmets. I normally use a fixed shade but in certain conditions I have to use an auto darkening helmet. My eyes feel like I have sand in them and I'm don with this helmet. I don't want to spend more than $250. Is there anything reliable that you would recommend?
