MONTREAL - These days, Mylene Gamache-Tremblay spends her evenings and weekends taking orders for solar eclipse glasses, and packing and shipping them around the eastern part of the country.
The demand has led to concerns that people will order glasses that don’t offer true protection, or worse, try to rely on sunglasses or welding glasses.
Most welding glass will not be #14 or #13. If it’s meant for stick welding, it’ll be [Edit to add, #7 was still common when I was welding stick, but is not recommended even for that, it was old-timers who were used to 6011 rods] #9 or #10 at the darkest, far too light. If for MIG it will be darker, #11-13; I set my shield to #11. TIG glass will be the darkest, and ideal.
Oxyacetylene cutting masks will be between a #4 and #6. Don’t watch the eclipse with those. Plenty of people will though.
Sunglasses, for reference, are typically going to be between a #1 and #3 shade. Definitely don’t stare at the sun through those
