They claim better vision of surrounding features - being able to follow a line, gap, seam, etc. (auto body welding is a PITA compared to structural.) THE PROBLEM: seeing the actual puddle when electric welding. Supposedly this improves that ability. I want that! THE OTHER PROBLEM: I have the sadistically expensive 3M Speedglas 9100FX-AIR that is at least 10 years old and am trying to find if there is a lens upgrade. I will never purchase a new air package welding helmet, they are just too stupid expensive $2000-3000. I lucked into mine and got a once in lifetime deal on it. QUSTIONS: Does True Color improve ability to see puddle? Is my 9100FX-AIR upgradeable? NOTE: have been searching internet for these answers and nothing so far.
