The Gateway Safety 36U50 Welding Glasses are really a pair of cup-style welding goggles: 50 mm double-walled eyecups, a rigid frame and 3 mm polycarbonate lenses with a shade 5.0 infrared filter, per the retailer listing. That makes them a fit for light gas welding, brazing and torch cutting, and the wrong tool for arc welding, which needs a much darker lens and a full helmet.
This review covers the specs the listings give, where the goggles fit, where they do not, and how to check the details before you buy.

What shade 5 means for your work
Shade 5.0 is a light filter. It suits tasks such as torch brazing, light gas welding and torch cutting, where the glare is far weaker than an electric arc. Arc welding (stick, MIG, TIG) needs a much darker lens, so use a proper welding helmet for those processes and follow the shade chart in your safety standard or the lens maker guidance.
If you mainly weld with an arc, these goggles are at most a supplement for grinding prep or helper use, not your primary eye protection.
Fit, venting and lens care
The double-walled eyecups with slot vents are meant to let heat and moisture escape while keeping sparks and debris out of the eye area. Venting reduces fogging but cannot eliminate it in heavy sweat or sudden temperature changes.
If you wear prescription glasses, check the fit before relying on the goggles for a full session, as the listings do not state whether they fit over frames. Clean the lenses with a soft cloth and lens-safe cleaner, never dry-wipe gritty lenses, and replace the goggles if the lens is cracked, deeply scratched or loose in the cup.

Who should buy them and who should skip
Buy them if you braze, gas weld or torch cut and want durable cup goggles with a shade 5 lens. Skip them if you arc weld, need full-face coverage, or want over-the-glasses fit confirmed first. In those cases look at a helmet or compare goggles in our other eye-protection reviews.

No. The retailer listing gives a shade 5.0 infrared filter lens, which is a light filter meant for tasks such as brazing, light gas welding and torch cutting. Arc welding needs a much darker shade and a welding helmet.
Do the Gateway Safety 36U50 goggles meet ANSI Z87?

How do you clean the lenses?
Rinse off grit first, then wipe with a soft microfiber cloth and a lens-safe cleaner. Avoid abrasive towels and harsh solvents that can scratch or cloud the lens.
