Sellstrom S79101 Flip Up Welding Glasses — Shade 5.0 IR, ANSI Z87.1+ (X35 Series)

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.

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.
