In the electric welding industry, we often hear the term inverter welding machine , but what is an inverter welding machine? Learn from the master of the Chongqing welding machine manufacturer:

Inverter welding machine is the process of changing DC power to AC power, using arc welding power source with inverter technology. The working process of the inverter welding and cutting equipment is to rectify and filter the three-phase or single-phase 50Hz power frequency AC power to obtain a smoother DC power. The inverter circuit composed of IGBT or field effect tube changes the DC power to 15 ~ 100kHz. Alternating current, after the voltage reduction of the intermediate frequency main transformer, rectify and filter again to obtain a smooth DC output welding current (or invert the AC power of the required frequency again); the control circuit of the inverter welding and cutting equipment consists of a given circuit and a drive circuit By processing the feedback of voltage and current signals to realize the whole machine cycle control, the pulse width modulation PWM is used as the core control technology, so as to obtain the constant current characteristics of fast pulse width modulation and the excellent welding process effect.
