MF DC Inverter Spot

Features

Insulated upside is convenient for other device installation. Avoid short circuit happen during installing welding fixture.
Use electro-pneumatic proportional valve. Gas pressure can be set quickly. It is controlled by controller. Easily program, store and recall the welding current, time and pressure.
DC output reduced the impact of welding current caused by secondary side induction. The power factor is almost 1. Output welding current can be fully constant and no zero crossing. Saved the energy, reduced production cost.
Parallel cooling water route is used in this machine. Every route can be adjusted and displayed separately. Warning function is working through water flow detector.
Pressure head up and down speed can be adjusted continuously. It reduced the impact to the work piece and reduced noise also.
Vertical type pressure mechanism has good following performance, low noise and long life.
Three phase power input ensured the balance among 3 phases. Based on 1000Hz invert frequency, the current control can be millisecond level, effectively increase the welding quality.
