GTT Scorpion: a high-output, two-stage Triple Mix production torch for large boro

The GTT Scorpion is one of Glass Torch Technologies’ production-class burners — a high-output, two-stage Triple Mix torch built for large borosilicate work and offered in 2- and 4-stud configurations. It belongs to the upper end of GTT’s range, where the job is sustained heat for heavy glass rather than fine detail. GTT publishes less hard detail on the Scorpion than on some other models, so a few specifics below are described qualitatively with an honest note to confirm them.

What the two-stage Triple Mix flame gives you

Triple Mix is GTT’s surface-mix technology: fuel and oxygen meet at the face of the torch, keeping the mixing chamber cool and giving a clean, penetrating flame that drives heat into the core of thick glass instead of just washing the surface — which is what large boro work needs. A two-stage setup lets you scale from a finer center flame up to a broad, hot one. For the underlying tech see GTT Triple Mix technology and surface mix vs premix torches; for why penetration matters on heavy boro, read soaking vs penetrating flame.

Who the Scorpion is for

The Scorpion suits advanced makers and production studios working large borosilicate who want a high-output surface-mix flame and the option of a 2- or 4-stud setup. It is not a soft-glass bead torch and not a beginner’s first burner.

Glass, fuel, and oxygen

The Scorpion burns propane or natural gas with oxygen and is built for boro. As a high-output production torch, its oxygen demand is substantial — realistically tanked oxygen or multiple concentrators. GTT doesn’t publish the Scorpion’s exact LPM (or, in the data we have, its jet count), so size your oxygen to your work and confirm the hardware specifics with GTT. Start with how many LPM does my torch need.

Where it sits in the GTT lineup

The Scorpion sits among GTT’s production burners, alongside torches like the Delta Mag and the versatile Kobuki, and above the two-stage Mirage. Like the rest of the line, it carries GTT’s family surface-mix flame behavior, so the move up from a smaller GTT is about scale and oxygen, not relearning the flame.

Before you buy

Budget for the whole system, not just the torch: an oxygen supply sized to a high-output production torch, the correct propane or natural-gas regulator, flashback arrestors on both lines, didymium eyewear, and serious ventilation. New to plumbing a torch this size? Start with the fittings, hoses & connectors guide and the glass torch safety setup guide.

Editor’s note: spec details reflect GTT’s own materials. GTT doesn’t publish the Scorpion’s jet count, exact oxygen flow (LPM), or current pricing, so confirm those specifics with GTT before purchasing.
