Review on Welding Darkening Breathable Grinding Adjustable Tools & Equipment by Steve Hauck

During TIG welding the hood kept switching from dark to light. No I didn't interrupt my arc, I checked the settings and the same battery problem changed the settings , the same problem. After my eyes burned out, I packed it up. I am a welder by trade and have several auto dimming fume hoods and have never had this problem. I can't find anything about customer service so I think 1 star is generous.
