Hey everyone,
I am a spectacled (and short-bearded) welder and I find that my 3M 7500-series respirator doesn't create a perfect seal. Around my nose there is often the tell-tale signs of an air leak in the form of small black marks of ultrafine grinding particles.
I have long noticed this and assumed I needed to tighten the mask more frequently, but only just worked out that it's because the nose pads want to sit exactly where the top of the mask needs to sit.
Does anyone know of another solution? I have a 3M SpeedGlas helmet, but can't really justify the cost of upgrading to the forced-air version since I only really weld a couple times a month.
