The helmet contains a fan, filter and cooling module to provide clean cool air that reduces welding fume levels in the breathing zone below suggested maximums. By providing cool air to the welders head and neck area their whole body will feel cooler. It suggests the use of an external power source to provide the energy required to have a fan of sufficient capacity to draw air thorough a quality filter so potentially hazardous constituents of welding fumes are captured. This externally supplied power allows the required cooling capacity thermal electric cooling modules to be used to significantly lower the ambient air temperature. This helmet allows the welding operator to have sufficient cooling to improve their overall work environment for one of the most objectionable welding issues, excess heat. | 12-02-2010 |
20110219506 | Cool, clean air welding helmet - An improved welding helmet encloses a welders head and a portion of the neck. The helmet contains a fan, filter and thermoelectric cooling module to provide clean, cool air that reduces welding fume levels below suggested maximums and provides cool air to the welders head and neck area making their body feel cooler. Air exhausted from the helmet is captured and further utilized to significantly improve system efficiency by causing it to be in contact with the hot side heat sink that is a part of the thermoelectric cooling module assembly. The use of an external power source, including readily available welding power, is suggested as one option for supplying system power. An optional configuration is presented where an external container strapped to the welders body is employed containing the fan, air filter and thermoelectric cooling module and is connected to the helmet by cool air intake and exhaust air hoses. | 09-15-2011 |
