一、概述手工交流电弧焊机调节电流,一般都是在焊机旁边焊工用手转动手柄,通过丝杠拖动活动铁芯(或活动线圈)位置进行调节的。但是,在焊接生产实践中,有时焊工操作处距焊机很远,调节电流很不方便。尤其是焊工不愿往返调节而使用不太合适的电流施焊时,往往降低了焊接质量。因此焊机的遥控是很需要的。 First, an overview Manual AC arc welding machine to adjust the current, usually welder hand next to the welder to rotate the handle, drag the movable iron core (or active coil) position adjustment. However, in the practice of welding production, sometimes the welder’s operation place is far away from the welding machine, and the current regulation is very inconvenient. In particular, welders do not want to round-trip adjustment and use less suitable current welding, often reducing the quality of welding. Therefore, remote welding machine is needed.
