GTT Samurai: a compact three-stage, 72-jet Triple Mix production torch

The GTT Samurai is one of Glass Torch Technologies’ three-stage production burners — a 72-jet Triple Mix torch built around a 7-jet Lynx center, a 33-jet Mirage middle, and a 32-jet outer fire. Like its close sibling the Ninja, it’s sized between the Kobuki and Delta Mag with a compact body that’s easy to work behind, and it’s aimed at fast melt-ins and production. The Samurai simply weights more of its 72 jets into the middle stage. A compressed-air path is available.

What the three-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 — what large boro and fast melt-ins demand. Three stages let you keep a fine center flame available while having a big soaking flame on tap. For the underlying tech see GTT Triple Mix technology and surface mix vs premix torches; for why penetration matters here, read soaking vs penetrating flame.

The compressed-air option

The Samurai can be ordered with GTT’s compressed-air path, which injects air into the fuel system so you can lower flame temperature while keeping the same flame chemistry and flame type. It’s a useful lever for tuning the flame without otherwise changing how the torch behaves. The full explanation is in GTT compressed air & 4-Way Mix.

Who the Samurai is for

The Samurai suits advanced makers and production studios who want big-torch heat and fast melt-ins from a compact body they can work close behind. It isn’t a soft-glass bead torch and it isn’t a beginner’s first burner.

Glass, fuel, and oxygen

The Samurai burns propane or natural gas with oxygen and runs both boro and soft glass, with its center of gravity firmly in large boro. As a three-stage production torch its oxygen demand is high — realistically tanked oxygen or multiple concentrators. GTT doesn’t publish the Samurai’s exact LPM, so size your oxygen to your work and confirm with GTT. Start with how many LPM does my torch need.

Where it sits in the GTT lineup

The Samurai slots between the Kobuki and Delta Mag among GTT’s three-stage production torches, as the Mirage-middle counterpart to the Phantom-middle Ninja. Both are built on the same Lynx center, so the flame behavior is familiar across the line; the choice between them comes down to how the jets are distributed across the stages.

Before you buy

Budget for the whole system, not just the torch: an oxygen supply sized to a three-stage production torch, the correct propane or natural-gas regulator (plus an air source if you take the compressed-air option), 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 Samurai’s exact oxygen flow (LPM) or current pricing, so confirm those specifics with GTT before purchasing.
