Industrial Mma (Igbt Module) - Metal, 560*280*520mm, Red | 0-630a Current Range, 20khz Inverting Frequency, Short Circuit Protection, Arc Force Adjustment, Energy Efficient

1.Use IGBT high power module and full-bridge inverter main circuit structure; the main engine with superior resistance to overloads and with outstanding welding performance; the welding machines with over 500A can be used as an ideal carbon arc air gouging power source.
2.Core control chip is the new-style current pulse width modulator; double loop feedback control; the more excellent static and dynamic characteristics; the smaller current drift.
3.With the arc force adjustment function, and adapt to all grades of welding electrodes.
4.The power factor is 0.98; the power consumption with no-load is less than 100W; it can save above 50% energy more than ordinary welding machines.
Short-circuit protection function and the special standby operating circuit; it will not damage the welding machine's life while no-load, and the whole welding machine's life is one time longer than similar products.
