DANGER WILL ROBINSON! While welder's glass blocks UV and reduces visible light to comfortable levels for welding it does not stop IR and is not reccomended for even unaided solar observation. 7x50 binoculars have 250+ times the light gathering power of a light adapted eye. If you are going to observe the Sun, get aluminized mylar solar filters for your binocs. They're cheap (especially compared to the possible consequences).

Welders' Goggles
Welders' goggles or the filters for welder's goggles with a rating of 14 or higher are safe to use for looking directly at the Sun. They are also relatively inexpensive."
Do you know something they don't know? I've been using this type of filter over my binocs for years. I don't look too often, (once you've seen a few spots they aren't too exciting). I would hate to be doing more damage than time itself is doing.
