Performance advantages : Emergency performance is good, and welding speed. Oriented by the small friction coefficient of special materials, the electromagnetic valve and cylinder direct connection speed up the reaction speed, and increase the rbi speed. The Lord loops adopt high-power transistor non-contact switch The main loop cooling water powers SCR components and outputs the current compensation function. High solid strength of the body Has impact resistance, and vibration rigidity, prevents electrode pressure head when sliding, and realizes welding stability.
