Overview

Not a pencil-flame tool for soldering, this Bernzomatic DuraCast is described as a heat shrink torch for large surface areas. The body is cast aluminum, and the title lists cooking and metalworking among its uses.

A wide surface of heat suits shrink tubing and vinyl wrap jobs better than a narrow flame. The listing does not say what fuel it uses, how it lights or how hot it runs.

Who it's for

Installers and crafters heating wide surfaces get a broad working area. Anyone doing fine soldering should pick a narrow-flame head instead, and buyers who need ratings should ask the maker.

Performance notes

A wide flame spreads heat over a larger area at once, which gives more even results on shrink tubing and film. Distance from the work and movement speed decide whether the material shrinks or scorches.
