电焊机是间断工作的电器设备,有相当多的时间处于空载耗电状态。为使电焊机在停焊间隙中不耗电或少耗电,各式各样的电焊机“节能器”已先后问世。这里,介绍一种技术上比较成功的交流电焊机空载节电装置。此装置能自动控制电焊机的断电与接通。当焊条与工件接触时,电焊机立即接上电源,保证正常焊接。焊接停止后,焊条离开焊件,电焊机也就自动断电。具有起弧迅速,工作稳定,安全可靠,节电效果明显的特点。
Welder is intermittent work of electrical equipment, there is a considerable amount of time in no-load power state. In order to make the welding machine in the stop welding gap or less power consumption, a wide range of welding machine “energy-saving device” has come out. Here, a technically more successful AC welding machine no-load saving device. This device can automatically control the welding machine off and on. When the electrode and the workpiece contact, the welding machine immediately connected to the power to ensure normal welding. After the welding is stopped, the welding rod leaves the weldment and the welding machine also automatically powers off. Arcing with rapid, stable, safe, reliable, energy-saving effect of obvious characteristics.
