Abstract
A shield for the protection of a welder's gloved hand and/or a welding instrument during a welding operation is provided having dual plates that define an air channel that allows a cooling flow of air through the air channel and past the plate that is in closest proximity to the welding operation.
Claims8
A shield for protecting a welder and/or a welding instrument from heat, sparks and slag of a welding operation, comprising:
- a front plate having a middle region, a peripheral region, and a contour defined by a first radius of curvature;
- a rear plate having a middle region, a peripheral region, and a contour defined by a second radius of curvature that is greater than the first radius of curvature;
- wherein the front plate is attached to the rear plate about a portion of their respective peripheral regions so that the middle region of the front plate is separated from the middle region of the rear plate to define an air channel for permitting air to pass between the front plate and the rear plate, thereby cooling the front plate and attenuating the transmission of heat to the rear plate.
A method of protecting a welder and/or a welding instrument during a welding operation, comprising:
- providing a shield including a front plate having a middle region, a peripheral region, and a contour defined by a first radius of curvature, a rear plate having a middle region, a peripheral region, and a contour defined by a second radius of curvature that is greater than the first radius of curvature wherein a portion of the rear plate peripheral region is attached to a portion of the front plate peripheral region so that the middle region of the rear plate is separated from the middle region of the front plate to define an air channel for allowing air to pass between the front plate and the rear plate, thereby cooling the front plate and attenuating the transmission of heat to the rear plate;
- and
- interposing the shield between the welding operation and the welder.
