What welding machine does covered electrode use? Can the inverter welding machine work?

If only 507 covered electrode is welded, you can choose ZX7 series inverter welder. ZX7 series inverter welding machine is suitable for DC manual welding, and can also take into account argon arc welding (adding argon, closing thrust and closing arc current).

There will be some differences in the performance of ZX7 series welders produced by different manufacturers, especially when welding 507 covered electrode. Welding machines with large output ripple may have unstable arc combustion or even broken arc. Therefore, when purchasing welding machines, try welding the commonly used 507 covered electrode before buying.

working process

The working process of inverter welding and cutting equipment is to rectify and filter three-phase or single-phase 50Hz power frequency alternating current to get smoother direct current. The inverter circuit composed of IGBT or field effect transistor changes the DC power supply into 15 ~ 100 kHz AC power supply, and after the voltage is reduced by the intermediate frequency main transformer, it is rectified and filtered again to obtain a stable DC output welding current (or the inverter outputs the AC power supply with the required frequency again).

The control circuit of inverter welding and cutting equipment is composed of given circuit and driving circuit. By processing the feedback of voltage and current signals, the whole machine can be controlled circularly, and the control technology with pulse width modulation (PWM) as the core is adopted, so that the constant current characteristics with fast pulse width modulation and excellent welding and cutting process effect can be obtained.
