(2) The upper electrode moves vertically up and down, and has a smooth adjustable working stroke and auxiliary stroke. The lower electrode can be adjusted vertically;
(3) Adopting a direct solenoid valve to accelerate the reaction speed, significantly increase the operating speed of the upper pressure head, and reduce air flow loss;
(4) The descent and ascent speed of the pressurization head can be adjusted arbitrarily, easing the impact of pressurization on the work and reducing noise;
(5) The secondary conductor adopts the upper insulation method, with stable and reliable insulation performance;
(6) The main circuit adopts a water-cooled high-power thyristor module, which has strong output, stability, and reliability, and the water distributor can be installed outside the equipment;
(7) All waterway components are made of copper and stainless steel, equipped with a visual water flow display to display the water flow situation;
(8) The operation is controlled by a foot switch, which has high production efficiency and low labor intensity.
(9) Equipped with a touch screen for quick switching of welding processes.
(10) The equipment has air and water pressure switches and alarms.
