Diffuser Shape Vent Slots in a Hand Torch Shield Castellation

摘要

A torch tip for a plasma arc torch includes a body having a first end, configured to attach to the torch, and a second end, where an end wall is disposed. A plasma exit orifice is formed in the end wall. At least two castellations are formed in the end wall. Each castellation has a castellation width defined by the distance between the sidewalls of that castellation. At least one slot is disposed between two castellations. Each slot has a slot width defined by a distance between the sidewalls of its adjacent castellations. The slot width can be at least twice the castellation width. Each slot also has a slot floor and an exterior shape. The slot floor can have slope that tapers toward the first end of the body in an outward radial direction and the exterior shape of the slot can have a generally V-shaped or U-shaped contour.

1. A torch tip for a plasma arc torch, the torch tip comprising:
a body having a first end and a second end, the first end of the body configured to attach to the plasma arc torch; an end wall disposed at the second end of the body; a plasma exit orifice formed in the end wall at the second end of the body; at least two castellations formed in an exterior surface of the end wall, each castellation having a castellation width defined by a distance between a first sidewall of each castellation and a second sidewall of each castellation at the second end of the body; at least one slot disposed between the two castellations, each slot having a slot floor and a slot width, and the slot width being defined by a distance between the first sidewall of a first castellation and the second sidewall of a second castellation adjacent the first castellation at the second end of the body, the slot width increasing with axial or radial distance away from the plasma exit orifice; wherein the slot width is at least twice the castellation width.
