仿苏—500型直流电焊机,可以改装供两把焊钳使用,这样可以解决电焊机不足或缺少小容量电焊机的困难。改装的方法很简单,只要把电焊机内部接线改一下,外面串联一个焊接变阻器就可以使用。这样改装后使用效果良好,现在简单介绍如下: 为了使两个电焊工在同时焊接时互不干扰,就必须使电焊机在焊接时的端电压保持稳定(或变化很小),一般在60～65伏特,因此,必须将原电焊机的差复激特性 Imitation SU-500 DC welding machine, can be modified for two welding clamp use, so you can solve the lack of welding machine or the lack of small capacity welding machine difficulties. Modified method is very simple, as long as the internal welding wire change, outside a series of welding rheostat can be used. This modified after the use of good results, and now briefly introduced as follows: In order to make the two welders at the same time welding without disturbing each other, we must make the welding machine in the welding terminal voltage remained stable (or small changes), usually 60 ~ 65 volts, therefore, the original welding machine must be poor Repulse characteristics
