The Sellstrom S79101 solves the torch worker's two-pairs problem: burn in Shade 5.0, then flip the shaded front up and inspect the cut through the ANSI Z87.1+ impact-rated base — eye protection never leaves your face. For oxy-acetylene cutting, brazing, and medium gas welding, that hinge is the whole argument, and Sellstrom executes it at a working-crew price.

Why flip up welding glasses earn their place
Gas work is rhythm work: heat, check, reposition, heat again. Fixed shade 5 glasses force a choice at every check — peer through green or push the glasses up and work bare-eyed, and the second option is how slag finds corneas. A flip front breaks the dilemma: the shaded lens handles the flame, the impact base handles everything else, and the hinge handles the transitions. That's why torch crews, maintenance welders, and HVAC brazers who tried flip-fronts rarely go back, and why the format spans our shelf from this Sellstrom to the 3M flip-up Shade 3 for lighter torch duty. Our full S79101 review and the welder's eyewear roundup place it in the field.
Safety first: Shade 5.0 is gas-process eye protection — never arc protection. MIG, TIG, and stick arcs require a welding helmet at a far darker shade; flash burn from an arc through Shade 5 is immediate and painful. And these are open safety glasses, not sealed goggles: heavy grinding dust or chemical splash hazard work calls for sealed eyewear instead. Match shade to process per OSHA's filter tables before the torch lights.
What the listing documents
From the listing: ANSI Z87.1+ high-impact rating; built-in Shade 5.0 infrared filter on a flip-up front; polycarbonate lenses in green shade over a black X35-series frame; 99.8% UV protection; universal size; stated duty of oxy-acetylene cutting, brazing, and medium gas welding — with the maker's own warning that arc welding requires a helmet at a much darker shade. Part number S79101. As oxy acetylene cutting glasses, that spec sheet covers exactly what the flame throws: IR, UV, sparks, and slag.
Shade 5 glasses across the shelf
If you'd rather have a fixed lens than a hinge, the shade 5 safety glasses field is deep: the Miller Electric and Hobart 770726 carry welding-brand pedigrees, the Bollé brings European comfort styling, and the Lincoln Starlite IR is the featherweight. Lighter processes step down to shade 3 with the Pyramex SB7950SF or HexArmor NX1. Sealed-coverage buyers should compare the Forney lift-front, Jackson flip-front goggle, and Sellstrom's own Odyssey II — the cutting goggle roundup sorts that branch.
Where glasses end and helmets begin
The honest boundary: Shade 5 eyewear owns the torch bench; the arc bay belongs to helmets. Can safety glasses be used for welding? answers the question process by process, the shade-number reference decodes the filter tables, and when your work crosses into arc territory the helmet guide and auto-darkening roundup take over. High-spatter cutting adds a face shield over the glasses; fume-heavy work belongs with welding respirators.
Ownership and program fit
Work the hinge before you trust it — a flip front that flops mid-cut is a hazard, not a convenience — and treat lens care like the consumable it is: rinse before wiping, retire at line-of-sight pitting. Verify the Z87+ and shade markings on arrival and log the pair into your eye-protection program like any other PPE.

Frequently asked questions
What is the Sellstrom S79101?
Flip-up welding safety glasses from Sellstrom's X35 series: an ANSI Z87.1+ high-impact polycarbonate base with a Shade 5.0 infrared flip front, black frame, universal fit. Made for oxy-acetylene cutting, brazing, and medium gas welding.
Can I arc weld (MIG/TIG/stick) in Shade 5 glasses?
No. Shade 5.0 handles the lower radiant intensity of gas processes only. Arc welding demands a welding helmet with a much darker filter — typically Shade 10 to 13 — plus full-face coverage. Treat these as torch, braze, and cutting eyewear, never arc protection.
How does the flip-up design actually help?
Torch work alternates constantly between burning and checking. The Shade 5.0 front flips up so you can inspect the cut, adjust the workpiece, or walk the shop with the impact-rated base lens still on your face — no pushing glasses onto your forehead, no juggling two pairs.
What does ANSI Z87.1+ mean on these?
The plus marks the high-impact (high velocity/high mass) rating of ANSI Z87.1 — the base lens is tested to stop the sparks, slag chips, and debris that torch cutting throws. The shade rating covers radiation; the Z87+ rating covers impact. You need both.
What is Shade 5.0 actually right for?
Oxy-acetylene cutting and welding, brazing, soldering, and similar gas-flame work — the listing's stated uses. Shade guidance ultimately comes from your process and OSHA's filter tables; our shade-number reference walks the selection through.
Do they block UV?
The listing states 99.8% UV protection, on top of the infrared filtering the green Shade 5.0 lens provides for gas work.
Glasses or goggles for torch work?
Glasses are lighter and easier to live in all day; sealed cutting goggles add wraparound splash, dust, and peripheral-flash protection and coexist better with respirators. High-spatter or overhead cutting generally argues for goggles or a face shield over the top.
Will these fit over prescription glasses?
They're universal-fit safety glasses, not an OTG (over-the-glass) design, and the listing doesn't claim OTG fit. Prescription wearers should compare a flip-front cutting goggle instead, which is built to cover eyewear.
Can I wear these under a welding helmet?
Many welders run shaded or clear safety glasses under a helmet as secondary protection — the glasses catch debris when the hood is up. That layered setup is standard practice; the helmet still does the arc-shade work.
What should I check when they arrive?
The Z87+ mark on the frame and lens, the shade marking on the flip front, smooth hinge action through repeated flips, and no optical distortion looking through both lenses. A flip front that droops mid-cut is a return.
How do I keep the lenses serviceable?
Rinse dust before wiping — dry-wiping grinds grit into polycarbonate — use lens-safe cleaner, and store them where the flip front isn't compressed. Retire them when pitting or scratches sit in your line of sight.
How do I order these for a full crew?
