摘要： A tip for use in a gas cutting torch is provided that includes an outer tip portion defining a central cavity and a distal orifice and an inner tip portion disposed within the cavity of the outer tip portion. The inner tip portion defines an outer surface, a central gas passageway in communication with the distal orifice of the outer tip portion, and an least one intermediate gas passageway extending from the outer surface to the central gas passageway for a flow of at least one gas to provide improved cooling to the tip.

摘要： A method of operating a plasma arc torch is provided that includes directing a first portion of gas into a plasma chamber, directing a second portion of the gas to initiate a pilot arc in the plasma chamber, and redirecting the second portion of the gas to form a shield gas flow rather than venting the second portion to atmosphere. A plasma arc torch for this method includes a start cartridge disposed between an electrode and a tip for initiating the pilot arc. The start cartridge defines at least one redirect gas passageway in fluid communication with a shield gas passageway. The second portion of gas is redirected through the at least one redirect gas passageway and into the shield gas passageway.
摘要翻译： 提供了一种操作等离子体电弧炬的方法，其包括将气体的第一部分引导到等离子体室中，引导气体的第二部分以在等离子体室中引发导电弧，并且重定向气体的第二部分以形成 屏蔽气体流动而不是将第二部分排放到大气中。 用于该方法的等离子弧焊炬包括设置在电极和尖端之间的启动盒，用于启动引导电弧。 启动盒限定了与屏蔽气体通道流体连通的至少一个重定向气体通道。 气体的第二部分被重新引导通过至少一个重定向气体通道并进入保护气体通道。

摘要： A method of starting an auto-ignition gas torch includes increasing a flow of oxygen above zero and increasing a flow of fuel gas to a level lower than the flow of oxygen for improved start reliability. In one form, the flow of oxygen is from about two times to about six times higher than the flow of fuel gas.
摘要翻译： 启动自动点火气体手电筒的方法包括增加氧气在零以上的流量，并将燃料气体的流量增加到比氧气流低的水平，以提高启动可靠性。 在一种形式中，氧气的流量比燃料气体的流量高约两倍至六倍。

摘要： A tip assembly for use in a gas cutting torch is provided that includes a tip and a mixer. The tip includes a tip central gas passageway and a distal orifice and the mixer includes a proximal end portion and a distal end portion. The distal end portion of the mixer is adapted for connection to the tip and the proximal end portion of the mixer defines a connecting member that removably connects the mixer to a torch head.
