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.

Automatic gas torch ignition in an oxygen rich environment

A method of directing a gas flow in a tip of a gas torch includes: directing a flow of gas to an outer passageway of the tip; directing the flow of gas inwardly through at least one intermediate gas passageway; directing the flow of gas to a central gas passageway of the tip; and directing the flow of gas distally through a distal orifice of the tip.

Method of directing a gas flow in a gas cutting tip

A method of directing gas flows in a gas torch includes directing a flow of a first gas and a flow of a second gas to a mixer central gas passageway of a mixer and directing the flow of the mixed first and second gases from the mixer to an axial passageway of a tip. The method further includes directing a flow of a third gas to an outer passageway of the tip, directing the flow of the third gas inwardly through at least one intermediate gas passageway, and then directing the flow of the third gas to a tip central gas passageway of the tip. Finally, the flow of the mixed first and second gases and the flow of the third gas are directed distally through a distal portion of the tip.

Method of mixing gases for a gas cutting torch

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.

Gas cutting tip with improved flow passage

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.
