New description: 【New technical field】 This is a gas-cooled water-cooled dual-purpose argon welder, especially one that can be used as an air-cooled or water-cooled argon welder, which is lighter and easier to carry. advantage. [Prior Art] According to the 'existing argon welder and its argon welding, the scaly is mainly used for the pure Nisaki protective electrode (such as tungsten rod) such as argon gas or ammonia gas. Because pure gas such as argon can effectively block the surrounding air, and it will not pollute the metal, and can remove the workpiece _ oxygen tilt during the arc welding process, it can successfully weld such as copper, 35, iron and not Record steel alloy. Although the argon arc welding has the above-mentioned characteristics and advantages, it is required to perform cooling at a high temperature operation condition in order to achieve the wire temperature of various alloys during operation. In conventional argon welders, the most common is the use of water cooling systems. However, when such an argon welder is water-cooled, the water tank, the _ phase, and the water source must be considered. The argon arc welding is performed in the work place, the argon welding machine and its related cooling are used. The heat dissipation effect is also required to be moved. However, if the above-mentioned water tank and pump parts are heavy, it is a problem in handling. Inconvenient, this is its main drawback. In addition, although Xi Gu grabs the cold structure of collecting money, it is often unsatisfactory for the air. [New content] The main purpose of this creation is to provide a gas-cooled water-cooled dual-purpose argon welder, which can be used for air-cooling or water-cooling _, especially for the air-cooled structure. The purpose of this creation is to provide a kind of air-cooled water-cooled argon suitable for use in workplaces with air pressure sources (such as Gongwei). -special
