3M Infrared Welding Flip-Up Shade 3 Safety Glasses — ANSI Z87.1+ Fits-Over

The 3M Infrared Welding Flip-Up Shade 3 (model 90033) is an ANSI Z87.1+ welding safety glass with a built-in Shade 3.0 infrared filter, designed for brazing, soldering, and light oxy-fuel cutting. The shaded lens blocks the bright light and IR of light gas processes while the impact-rated polycarbonate base shields against sparks, slag, and debris. It's a fits-over (OTG) design that wears over most prescription eyewear, and the flip-up lens lets you switch between shaded and clear vision without removing the frame.

Why the 3M Infrared Welding Flip-Up suits gas work

Brazing, soldering, and light oxy-fuel cutting throw off bright light and infrared a clear lens won't filter — but they don't produce the blinding radiation of an electric arc. This 3M flip-up fits that middle: a Shade 3.0 IR filter to cut the glare and IR of light gas processes, on an impact-rated base that stops sparks and slag. Two features set it apart — it fits over your prescription glasses, and the shade flips up so you get clear vision between welds without taking the frame off. Our full 3M welding flip-up review rates it 4.4/5, and the safety glasses buyer's guide covers matching eyewear to the task.

What the listing documents

From the published specs: an ANSI Z87.1+ welding safety glass with a built-in Shade 3.0 infrared filter for brazing, soldering, and light oxy-fuel cutting; an impact-rated polycarbonate base that shields against sparks, slag, and debris; a fits-over (OTG) design that wears over most prescription eyewear; a flip-up lens to switch between shaded and clear vision; model 90033. As 3m safety glasses go, this is the flip-up shade — a genuine flip up welding safety glasses and a true shade 3 welding safety glasses for light gas processes.

Choosing the right shade for the process

Shade selection is a safety decision, not a preference: too light a shade lets harmful radiation through. Shade 3.0 covers brazing, soldering, and light oxy-fuel cutting; heavier gas cutting and gas welding need a darker shade. Always match the shade to the process and its radiation level using a recognized OSHA/ANSI shade selection chart. Compare other shaded options in the welding safety glasses collection, and the broader eye protection collection for face shields and helmets where the process demands them.

Where it sits in the 3M line

This flip-up is 3M's dedicated fits-over welding shade; the anti-fog flagship Solus 2000 also offers IR-shade variants for gas work, while the SecureFit and premium Solus 1000 are the general non-shaded frames, and the Virtua CCS adds a tether for on-off task work. Keep a clear, non-shaded glass from the clear-lens collection for the non-welding parts of the job, and an anti-fog model where hot gas work fogs the lens.

Where it fits by job and crew orders

The Shade 3.0 fits-over flip-up suits brazing, soldering, and light cutting in fabrication and maintenance — especially for prescription-glasses wearers — with the construction, manufacturing, and mechanics guides ranking frames by task, and smaller-faced wearers should check the small-face guide and women's fit guide. For arc welding use a proper helmet; where the hazard adds splash or fumes, add a sealed goggle from the safety goggles collection or a respirator.
