上海劳动电焊机厂最近试制成功了一台适用于铝及铝合金板全位置焊接的推拉式送丝熔化极半自动氩弧焊机。可焊铝板厚度为8毫米至25毫米。送丝软管长达15米。焊机配用ZPG_2—500型硅焊接整流器。焊机以简单的线路保证了推丝和拉丝马达的同步。其方法是采用100瓦它激电动机拖动推丝机构,用15瓦串激电动机拖动焊枪上的拉丝机构。拉丝串激电动机与推丝他激电动机电枢并联。由于二者功率相差甚殊与电机励磁原理上
Shanghai labor welding machine factory recently successfully trial-produced a suitable aluminum and aluminum alloy plate all-position welding push-pull wire melting semi-automatic welding machine. Weldable aluminum thickness of 8 mm to 25 mm. Wire feeding hose up to 15 meters. Welder equipped with ZPG_2-500 silicon welding rectifier. Welder with a simple line to ensure that the wire and wire drawing synchronization. The method is to use 100 watts of its motivation to drag the wire pushing agencies, 15-watt string motor drag drag on the drawing agency. Brushed string excited motor and push his excited motor armature in parallel. Because of the difference between the two power and motor excitation principle
