在开展计划用电、节约用电、群众办电的群众运动中,我们针对交流弧焊机空载损耗大,功率因数低,白白浪费电能的缺点,制作了一种焊机节电控制器。当焊机与工件接触时焊机电源自动接通,停焊后控制器经一定延时后自动断开焊机电源,从而达到空载节电的目的。本控制器特点:体积小、重量轻、结构简便、焊机 In carrying out planned electricity, electricity conservation, the masses run the mass movement, we arc AC welding machine no-load loss, low power factor, wasted energy shortcomings, to create a welding machine controller. When the welder and the workpiece contact welding power automatically connected to stop the controller after a certain delay automatically disconnect the welder power, so as to achieve the purpose of no-load power. The controller features: small size, light weight, simple structure, welding machine
