1. With a unified patent kai erda igbt inverter power platform.
2. With gas shielded welding, manual welding, simple welding, carbon arc gouging multi-phase welding function.
3. Can be welded low carbon steel, high strength steel, ordinary steel; widely used in petroleum, electric construction, metallurgy, boilers, pressure vessels, pipes, vehicles and other manufacturing industries.
4.The welding parameters are fully controllable, the current and voltage preset accurate, easy to upgrade functions.
5. The peak current control mode, to ensure stable and reliable work of power devices.
6. Power devices using imported dual-chip igbt chip full-bridge inverter.
7.Waveform control technology, according to the welding needs to change the welding output waveform, arc shape, the amount of spatter and weld formation. 8. A good anti-grid fluctuation capability, the input voltage 156v-560v can still guarantee welding
8. A good anti-grid fluctuation capability, the input voltage 156v-560v can still guarantee welding.
