MIG TORCH HEAD SHIELD

Abstract

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.

[0018] Reference is now made in detail to the description of the embodiments as illustrated in the drawings. While embodiments are described in connection with the drawings and related descriptions, there is no intent to limit the scope to the embodiments disclosed herein. On the contrary, the intent is to cover all alternatives, modifications and equivalents. In alternate embodiments, additional devices, or combinations of illustrated devices, may be added to, or combined, without limiting the scope to the embodiments disclosed herein.

[0019] Referring to FIG. 1, an illustrated view of an exemplary MIG torch head shield 100 for additional safety while performing MIG welding is presented. The head shield 100 protects the welder's eyes from arc flash (infrared and ultraviolet radiation) by attenuation of the arc intensity at a distance normal to welding procedures. The MIG torch head shield 100 is useful for increasing a safety zone of arc flash for eye protection. The MIG torch head shield 100 is further useful for allowing increased safety and ability to lighten a percentage of shade setting inside of auto-dimming helmets.

[0020] The MIG torch head shield 100 is preferably made of a high temperature plastic material, however other materials are hereby contemplated, including, but not limited to metal, etc. The MIG torch head shield 100 is preferably disposable, however the MIG torch head shield 100 may be reusable. The MIG torch head shield 100 is preferably flexible, thereby allowing for welding in tight areas without the MIG torch head shield 100 to not interfere. The MIG torch head shield 100 is a tinted shade.

[0021] The MG torch head shield 100 may have a removable, disposable inner lining 305 inside of the sidewall 304 to reveal a new clean surface for visibility, as the previous liner gets contaminated by arc spatter and outgassing of the welding process. The inner lining 305 will be of a high temperature plastic of a clear tint. Only the outer main embodiment will have the protective tinting needed to shield the user from the arc flash and radiation of the high intensity light.

[0022] The MIG torch head shield 100 has a coupling portion 200 and a cone portion 300. The coupling portion 200 of the MIG torch head shield 100 has an inside 201, a first end 202 and a second end 203. The coupling portion 200 of the MIG torch head shield 100, will be further described in FIG. 2, is useful for friction coupling of the MIG torch head shield 100 to a MIG welder nozzle 700. The MIG torch head shield 100 is preferably made of a single material or film, however each of the coupling portion 200 and the cone portion 300 may be made separately.

[0023] The inside 201 of the coupling portion 200 of the MIG torch head shield 100 is necessarily hollow. The coupling portion 200 preferably has a diameter of thirteen-sixteenths ( 13/16) inch, however other diameters are hereby contemplated, including, but not limited to, one-half (½) inch, three-fourth (¾) inch, etc.

[0024] The cone portion 300 of the MIG torch head shield 100 has a first end 301, a second end 302, an inside 303 and a sidewall 304. The inside 303 of the cone portion 300 of the MIG torch head shield 100 is hollow. The cone portion 300 of the MIG torch head shield 100 is preferably flexible. The first end 301 of the cone portion 300 of the MIG torch head shield 100 is coupled to the second end 203 of the coupling portion 200 of the MIG torch head shield 100. The second end 302 of the cone portion 300 preferably has a diameter of one and one-half (1.5) inches, however other diameters are hereby contemplated, including, but not limited to, one and one-fourth (1.25) inches, two (2) inches, etc. The sidewall 304 of the cone portion 300 preferably has an angle of thirty degrees (30°), however other angles are hereby contemplated, including, but not limited to, forty-five degrees (45°).

[0025] Moving now to FIG. 2, an illustrated view of a MIG torch 400 with the MIG torch head shield 100 shown in FIG. 1 is presented.

[0026] The MIG torch 400 has a torch base 402 and a tip 403. The first end 201 of the coupling portion 200 of the MIG torch head shield 100 is placed over the tip 402 of the MIG torch 400 and is slid or maneuvered where the torch base 402 of the MIG torch 400 is on the inside 201 of the coupling portion 200 of the MIG torch head shield 100. The coupling portion 200 remains coupled to the torch base 402 of the MIG torch 400 by friction but not limited to friction (i.e. banding, clamping, springs, etc.). The tip 403 of the MIG torch 400 preferably extends one-fourth (¼) inch to one-half (½) inch (user-adjustable) from the second end 302 of the cone portion 300 of the MIG torch head shield 100, however other extended lengths are hereby contemplated, including, but not limited to, one-half (½), three-quarters (0.75) inch, one and one-half (1.5) inches, etc.

[0027] The coupling portion 200 further receives a nozzle 700. The coupling portion 200 of the MIG torch head shield 100 preferably has a retaining device 204, such as a spring retaining device, however other devices are hereby contemplated, including, but not limited to, rubber band 205, c-clip 206, etc.

[0028] Referring now to FIG. 3, an illustrated view of an arc flash 500 of the MIG torch 400 shown in FIG. 2 with the MIG torch head shield 100 shown in FIG. 1 is presented.

[0029] The tip 403 of the MIG torch 400 is performing a weld on a piece of metal 600. The metal 600 oxidizes and expels an arc flash 500 from the heated metal 600. The arc flash 500 is shown where the arc flash 500 is reduced by making contact with the inside 303 of the cone portion 300 of the MIG torch head shield 100.
