Abstract:
1. A welding helmet including an anti-blinding device to selectively and conveniently control a welding operation and a grinding operation, the anti-blinding device serving to protect welder's eyes from light emitted from a welding or cutting torch during the welding or grinding operation, wherein a switch is provided at an outer surface of the welding helmet, the switch being turned on or turned off to switch the anti-blinding device from a welding operation mode to a grinding operation mode or vice versa, wherein the switch includes a case provided at a bottom surface thereof with a fitting protrusion and the welding helmet is formed at a lateral position thereof with an electric line insertion hole and a fitting hole, whereby the fitting protrusion of the switch is fitted into the fitting hole to couple the switch to the welding helmet, wherein the switch comprises a curved surface to allow the welder to operate the switch by sliding a finger over the switch, and the switch further comprises a plurality of mark protrusions formed on the curved surface to allow the welder to easily locate the switch, wherein the switch is configured to hide the curved surface when the welding helmet is viewed from a front of the helmet, wherein the switch is configured to rapidly switch the anti-blinding device from the welding operation mode to the grinding operation mode or vice versa, wherein the anti-blinding device includes a liquid crystal display or a control panel to indicate a current status thereof by displaying words “Welding” and “Grinding,” and wherein a Light Emitting Diode (LED) lamp is embedded in the welding helmet so as to be turned on during a grinding operation for easy recognition of a current status.
