Abstract: A rotating power connection for connecting an electrical supply power cable to an electric welding torch body is provided. In the rotating power connection, the mechanical load is carried by steel bearings, and the electric load is carried by multi-contact, spring loaded fins made out of highly conductive materials or coatings. In some examples, a rotating power connector is affixed to a torch before the power connection to a wire feeder. The rotating power connector advantageously allows for rotation of the welding torch relative to the unicable while providing continual electrical connection at the high current levels employed in welding applications.

Abstract: Some examples of the present disclosure relate to a cover cap for a welding torch. The cover cap is attached to a housing of the welding torch and rotatable between a closed position, where the cover cap covers an access port of the welding torch, and an open position, where the cover cap does not cover the access port. The welding torch may have welding components within the handle that may be accessed through the access port when the cover cap is in the open position. A cap holder may be used to hold the cover cap in the open position.

Abstract: Some examples of the present disclosure relate to welding torches having a thermal insulating plate (400). The thermal insulating plate is comprised of a thermally insulating material, and is positioned between a front housing (302) and a drive gearbox (324) of the welding torch. The front housing (302) is connected to a gooseneck that conducts electrical energy to a torch tip (i.e. front end) of the welding torch. The drive gearbox (324) includes a gear assembly configured to drive a drive roll that moves a wire electrode through the welding torch (e.g. toward the torch tip of the torch). The thermal insulating plate (400) acts as a heat dam to decrease and/or reduce thermal energy transfer from the torch tip of the welding torch (e.g. via the front housing) towards the rear of the welding torch (e.g. through the drive gearbox), where the thermal energy may heat the welding torch handle and/or damage some of the more expensive and/or sensitive components in the handle (e.g. a motor of the drive gearbox).

Abstract: The present disclosure relates to a welding torch having a clasp (300) that couples a protective sleeve (150) to a welding torch through a strain relief (200). The protective sleeve (150) encloses a welding cable assembly. The strain relief (200) encircles a portion of the protective sleeve (150). The protective sleeve (150) is further fitted over a ball swivel that is coupled to a handle (38) of the welding torch. The clasp (300) clamps over the strain relief (200), protective sleeve (150), and ball swivel to securely couple the protective sleeve (150) to the welding torch.
