Plasma torch

A plasma torch.

A plasma torch is a handheld device used to generate a directed flow of plasma, called a "plasma jet."

The torch works by heating deuterium plasma, using an oscillating positron beam. The plasma is then compressed, and shaped by a strong magnetic field, which uses the torch's nickel-rhombium ceramic electromagnets.
The heated plasma is then vented through a tapered ceramic-polymer nozzle to produce a plasma jet.

Plasma torches are typically cylindrical, with a tapered nozzle at one end, though the exact form varies between the species that use such tools. The lower section of the device has a non-slip surface, which allowed it be held comfortably with one or two hands. The body of the tool has power controls that allow the user to regulate the flow of plasma.

With a higher energy density than laser and phaser torches, plasma torches have the advantage of being able to cut and weld thicker and more durable materials. On its highest setting, a plasma torch can cut a hole 1 meter deep in solid duranium or tritanium in fifteen minutes. Welds made with a plasma torch are more tolerant of joint gaps and misalignment, and can cut and weld faster when compared to other types of torches. Plasma torches can also be used for "plasma spraying," a process used to coat a surface by spraying it with a melted material.

Unlike other types of torches, plasma torches are unable to cleanly cut non-metallic or brittle materials. Their greater heat output has the potential to cause thermal deformation of the material near the cut or weld site.
Plasma torches tend to be less precise, due to the plasma jet affecting a larger area of the target material. Additionally, the device has a limited effective distance. This requires the torch’s operator to be in close proximity to the
target material, which may pose a safety hazard. As such, the Starfleet Regulatory Agency requires that appropriate safety protocols are in effect while using this device.
