Abstract: A TIG welding torch (10) including a torch body (22), a metallic front section of the torch body (22) for holding a tungsten rod and conducting electricity to the tungsten rod, and a ceramic nozzle (48a,b,c) for surrounding the metallic front section, wherein a heat isolation spacer (36a,b,c) is provided between the metallic front section and the ceramic nozzle (48a,b,c), the nozzle (48a,b,c) bearing against the outside of the heat isolation spacer (36a,b,c), the heat isolation spacer (36a,b,c) being attached, at a point of attachment, to the metallic front section at a rear end of the metallic front section and a rear end of the heat isolation spacer (36a,b,c), and the heat isolation spacer (36a,b,c) extending forwards of the point of attachment, spaced from the metallic front section to provide a thermal break between the nozzle (48a,b,c) and the metallic front section, and the ceramic nozzle (48a,b,c) being in contact with the heat isolation spacer (36a,b,c) forward of the point of attachment when the cera

Abstract: A TIG (Tungsten Inert Gas) welding torch (10) comprises a torch body (22), a collet (38a,b,c) for retaining a tungsten rod, and a back cap (42), in which the collet 838a,b,c) passes through an aperture in the torch body (22) from the front of the torch body (22) to the rear of the torch body (22), and is joined directly to the back cap (42) by a screw thread (40a,b,c), the collet (38a,b,c) being drawn backwards against a front section of the torch body (22), to close the collet (38a,b,c) and retain the tungsten rod when the screw thread (40a,b,c) is tightened.

Abstract: A welding torch 10 is provided for use in a Gas Metal Arc Welding (GMAW) process. The welding torch 10 includes a torch body 12, a welding tip 16 extending from the torch body 12, and a detachable nozzle 22 which substantially surrounds the welding tip 16 in use to direct gas around the welding tip 16 and onto a workpiece, the nozzle 22 having a front end which faces the workpiece in use and a rear end which attaches to the torch body 12 in use, in which a ring 24 is provided, the ring 24 being substantially axially fixed to the nozzle 22 at the rear end of the nozzle 22, and the ring 24 being rotatable with respect to the nozzle 22, the ring 24 having a screw thread and the torch body having a corresponding screw thread 26, for fixing the nozzle 22 to the torch body 12.

Abstract: Wedge-shaped shelf attachments are located on a shelf of a display case to provide a support surface against which a row of products, such as frozen food boxes, can be stacked. The attachments are located on the shelf so as to display the products at the front of the shelf thereby providing the appearance of a filled shelf.
