Nozzle for a plasma arc torch

The invention relates to a single or multipart insulating component for a plasma torch, particularly a plasma cutting torch, for electrical insulation between at least two electrically conductive components of the plasma torch, characterized in that the insulating component consists of an electrically non-conductive and easily thermally conductive material, or at least one part thereof consists of an electrically non-conductive and easily thermally conductive material. The invention further relates to assemblies and plasma torches having the same and to a method for processing, plasma cutting and plasma welding.

Single or multi-part insulating component for a plasma torch, particularly a plasma cutting torch, and assemblies and plasma torches having the same

The invention relates to a plasma torch, preferably to a plasma cutting torch, in which a plasma gas PGand/or PGflows through at least one feed through a housing of the plasma torch gas up to a nozzle opening. A hollow space connected to the feed(s) is also present within the housing and a valve which opens and closes an opening is arranged at the opening at said hollow space and a leading off of plasma gas PGand/or PGout of the feed(s) up to the nozzle opening can be achieved in the open state of this valve.

Plasma torch

A plasma torch head, a plasma torch shaft and a plasma torch for providing a quick and simple possibility of changing the plasma torch head are described.

Plasma torch head, plasma torch shaft and plasma torch

Connection between a plasma torch wearing part and a plasma torch wearing part holder, plasma torch wearing part and plasma torch wearing part holder.

Interconnection arrangement for a plasma torch wearing part and part holder

A nozzle for a liquid cooled plasma torch includes a nozzle bore for the exit of a plasma gas beam at a nozzle tip, a first section, of which the outer surface is essentially cylindrical, and a second section connecting the nozzle tip, of which the second section the outer surface tapers essentially conically towards the nozzle tip, wherein at least one liquid supply groove is provided and extends over a part of the first section and over the second section in the outer surface of the nozzle towards the nozzle tip and at least one liquid return groove separate from the liquid supply groove is provided and extends over the second section.

Nozzle for a liquid-cooled plasma torch, nozzle cap for a liquid-cooled plasma torch and plasma torch head comprising the same

A nozzle protection cap for an arc plasma torch comprises a front end section and a rear end section with a thread region on its inner surface for screwing to a torch body of an arc plasma torch. At least one groove crosses the thread region on the inner surface. A nozzle protection cap holder for the arc plasma torch comprises a section with a thread region on its outer surface for screwing to the nozzle protection cap. At least one groove crosses the thread region on its outer surface. An arc plasma torch comprises a torch body and a nozzle protection cap screwed thereto in a screw connection region. The torch body and/or the nozzle protection cap is/are designed so that at least one channel is formed between them, the channel crossing the screw connection region.

Protective nozzle cap, protective nozzle cap retainer, and arc plasma torch having said protective nozzle cap and or said protective nozzle cap retainer
