What protective eye ware is recommended for silver solder? Can the same be used for filet brazing? I am no longer able to TIG weld because my seventy year old eyes cannot handle the glare. Instead of seeing the puddle in detail I just see an area of orange glare. I have been through every combination of helmet, lenses and glasses. Nothing works. I am hoping that the much less bright light of brazing will allow me to continue. Thanks, Jerry
Silver, technically, does not require any UV protection, if it is used at the cold end. Doing fillets with 45% gets pretty hot for me, and I wear sunglasses type lenses in safety form, because I only do this a little not day in day out. For the hot end of things there is Didymium, which was recently discussed in another brazing post.
A TIG alternative is gas welding bike tubes. There is one pro who does this that I know of, but I lost his contact/website info. There is a good 4130 gas welding DVD set that you can rent or buy. Smartflix does the rentals. I use these glasses for that:
if all you are doing is working with silver, something with didymium (ACE) cut down the glare from the flux nicely. I spent a lot of time looking at this since my eyes are a mess. I ended up getting ACE with #2 shade. They are on this page with shade opt GB-P2-FO I got the fitover style, they work really well with my glasses unless I'm sweating too heavily.
These work for brass too. I've done some welding with them, and they work, but I probably should figure out how to make something darker work for me. Bifocals mess everything up.
There are better glasses, but I didn't really feel like spending $300 when didymium works fine for most everything I do.
OSHA recommends #3 shade for brazing, I find it much too dark.
