Poll: "Has anyone used both the Burtweld and the Tinman lenses?"
Answer: Yes, I have used both. And I know many others who have also.
Heard a lot of feedback on green welding lenses, since 1989.
"Better than Burts" has been heard a time or two, on the other hand ...
Every welder has hissown particulars .....
..... Hanna, Epperle, Hagemann Sr, Troutman, Tweit, Remington, Berger ....
...... so many fab guys over so many years .....
("Hey Kent, I love your lenses - still have my old Burts though, in a box on the shelf. Let me know if anybody wants a set of old Burts.")
FYI, "Shade" or "darkness/shading" of welding filter:
Burts are the S4 shade, "Light" shade for some brazing, welding some aluminum, (according to the AWS specs for welding filters.)
TM2000 are the S5 shade, "Standard" shade for general gas welding - including:
Welding steel, 4130, stainless alloys, cast iron .... and aluminum.
Meets ANSI Z87, current dates.
(Shade S3 - glassblowing lenses = didymium lenses, a combo of 2 rare earth oxides - praseodymium + neodimium = DI-dymium.
)
Note: According to Optometrist info: "The need for light doubles after the age of 45. Doubles again at 55. Doubles again at 65." .... and etc.
Some folks reach their 70's without needing any correctives for vision.... maybe reading glasses?
Note 2: The odd duck that is "color blind" usually has good/excellent night vision / low light vision. (the rods and cones on the retina vary in ratio but not density. More rods = night vision, but means fewer cones = poor color distinction.))
