The present invention relates to methods and apparatus for detection of fire states in the presence of welding activities. In some examples, the welding detection system may algorithmically calculate a risk of a fire state developing. In some embodiments, the welding fire detection and prevention system may communicate warning states to users, supervisors, equipment and/or building monitoring systems.

A MIG torch head shield for protection of the eyes from arc flash during the welding process. The MIG torch head shield is further useful for allowing increased safety and ability to lighten a percentage of shade setting inside of helmets. The MIG torch head shield is also useful for providing a shaded or tinted vision of the arc welding when a helmet is not worn by a welder.

A fastening system for welding a welding stud in a welding direction to a substrate is provided, comprising a welding gun, which defines the welding direction, and the welding stud, wherein the welding gun has a holding device for holding the welding stud during a welding process and an outer contour, wherein the welding stud comprises a contact surface, which is provided for making contact with the substrate before and/or during the welding process, and wherein, starting from the contact surface, a tangent can be applied to the outer contour, which encloses an angle of less than 60° with the welding direction when the welding stud is held by the holding device and the contact surface is in contact with the substrate.

A welding accessory apparatus can include a welding lens, a manifold, an articulated arm assembly, and a tube. The welding lens can be mounted to the manifold. The manifold can have an intake aperture, an outlet aperture, and an internal cavity. The articulated arm assembly can be interconnected with the manifold and be adjustable whereby a user can position the manifold and the welding lens among different positions and orientations in three dimensions and then retain the manifold and the welding lens in the selected position and orientation. The tube can be interconnected with the manifold and can communicate with the intake aperture and the internal cavity by way of the outlet aperture. At least part of the tube can be moved and held in place with the manifold and the welding lens by the articulated arm assembly.

A protective cover for a remote device for welding equipment is provided. In some examples, the protective cover is configured as a fitted and sacrificial protective cover configured to prevent damage to the remote device from byproducts of a welding process.

Systems and methods to aid a welder or welding student. A system may provide a real-world arc welding system or a virtual reality arc welding system along with a computerized eyewear device having a head-up display (HUD). The computerized eyewear device may be worn by a user under a conventional welding helmet as eye glasses are worn and may wirelessly communicate with a welding power source of a real-world arc welding system or a programmable processor-based subsystem of a virtual reality arc welding system.

A male welding lead connector apparatus including a slidable member to block the male welding lead connector from rotating relative to a female welding lead connector when the two connectors are engaged with one another. A method of locking a male welding lead connector to a female welding lead connector using a special male welding lead connector including a slidable member to block the male welding lead connector from rotating relative to a female welding lead connector when the two connectors are engaged with one another.

The present invention relates to methods and apparatus for detection of fire states in the presence of welding activities. In some examples, the welding detection system may algorithmically calculate a risk of a fire state developing. In some embodiments, the welding fire detection and prevention system may communicate warning states to users, supervisors, equipment and/or building monitoring systems.

A welding shield that is configured to provide improved gas distribution adjacent a weld seam during the welding process so as to improve the weld quality. The welding shield includes a central member wherein the central member includes contiguously formed sidewalls and a top wall operable to create an interior volume. Mounted within the interior volume is a gas distribution module that is operably coupled to a gas source. A clip member is mounted to the central member and is configured to provide retention of the gas distribution module. A torch retention member is movably mounted to the top wall of the central member. The torch retention member is configured to receive and secure a welding torch and further provide rotational and pivotal movement thereof. A plasma cutter holding member is further included and is operable to releasably retain a plasma cutter.

A portable welding ground attachment system used to attach a welding ground clamp (also called a work clamp or work cable) of an arc welder to a workpiece to be welded. The system is particularly useful in establishing positive connections between a work cable and extended lengths of pipe.
