A Fusion Torch is a Tau utility tool issued to XV46 Vanguard Void Battlesuits to aid them in exploring the hazardous interior environments of Space Hulks. A Fusion Torch is a short-ranged and very high-powered Melta cutting tool, utilising an atomic fusion reaction to generate an immensely hot beam capable of cutting through even the thickest of bulkheads and barriers. Whilst designed to breach obstacles, a Fusion Torch can also be used as an incredibly potent, if clumsy, close combat weapon capable of vaporising anything that its wielder happens to target within reach of its beam.
