SAFETY GAS WELDER

The utility model belongs to flame welding equipment. In order to overcome the problems of the transportation and the storage of hazardous gases, such as acetylene and oxygen in the welding process, the project of the safety gas welder using electrolytic water is provided particularly. In the project, the designs of novel components are adopted and improved on the basis of the predecessor's welders. In the utility model, the components of an integral cylinder body gas-water diffluent electrolytic cell, a gas-water diffluent fin type radiator, a gas mixer with hybrid screw threads and different screw pitches, a double-layer sleeve wall-attached airflow type secondary gas-water separator, etc. are adopted. Two flammable air sources which can be selected to use or can be matched to use are arranged in the project. The utility model has the characteristics of stable working flame and wide temperature regulation range.
