Advantages
(1) . The lowering and rising speed of the pressure head can be adjusted at will, which alleviates the pressure impact on the work and reduces the noise;
(2) The secondary conductor adopts the upper insulation mode, and the insulation performance is stable and reliable;
(3) The main circuit adopts water-cooled high-power silicon controlled rectifier module, with strong, stable and reliable output;
(4) The water circuit elements are all made of copper and stainless steel, and equipped with visual water flow display to display the water flow;
(5) The operation is controlled by foot switch, with high production efficiency and low labor intensity.
