Now, the inverter welder is moving in the digital direction, and the best inverter welder is the digital type that guarantees the contravariant. Digital welding technology adopts digital technology (SCR silicon controlled rectifier welding machine), which has no significance in the development of digitalization, because its frequency is too low and the dynamic response is too slow. Its performance can't be digitized. The melting point has been greatly extended and the welding performance has been improved. To be sure, the welding machine market is a digital inverter.
When choosing digital welder, it should be carefully distinguished. Digital welding machine is the future development direction, all sellers want to advertise under the sign of digital technology. The key to differentiating the digital machine is whether the hard core that controls the current and PWM launches is digital or controlled by the DSP. Therefore, only the core cotroll is digital, the real digital machine is realized, and the welding performance is prompted by accually. Some welders are not truly digital, using only digital waterworks, showing current, voltage, etc., and people in the street are hard to tell.
