The byproduct of the combustion triangle is a 10,000 degree particle stream. An operator merely brings the particle stream into contact with the parent material for melting to take place. The Magnum torch also allows the operator a considerable degree of control over the oxygen pressure by way of a micrometering valve attached to the torch lever. Tubes will efficiently run with as little five pounds oxygen pressure. A magmatube consists of a seamless copper coated steel tube with an inner wire fuel recipe crimped inside forming a radial axis.
Oxygen flows through the spaces between the wire for consistent combustion at low pressure.
The wire fuel recipe is recessed at one end of the tube to stop fusion near the torch head. The tube and wire are balanced for smooth consistent burn characteristics. The tubular design serves both as a conduit for the internal delivery of oxygen and a means for focusing the thermic stream for the efficient removal of vaporized material . A focused internal stream allows for greater control of heat. Two copper contact plates are secured within an insulated phenolic handle for cause ignition.
