What is the reason of copper stick welding machine
Need to choose the welding head material according to different material welding workpiece. If you are using copper for welding, when welding workpiece coating will appear when the sticky situation.
Touch welder briefly introduced: AC voltage touch welding machine, usually with large transformer + semiconductor SCR control the conduction time, so as to control the energy of spot welding. To put it bluntly, a high power transformer turns the 220V alternating current into a low voltage, while the current is magnified by N times; the workpiece is clamped on the upper and lower electrodes.
Because when the copper stick welding machine welding workpiece coating will appear when the sticky situation.There are two kinds of touch welding machine, AC voltage type and DC capacitor type (that is, energy storage welder).
