IGBT Module Small Portable D/C Manual Arc Welding Machine of Zx7-300

Character of product

It is the forth generation welding machine of 220v/380v. When grid voltage fluctuates, it can distinguish exactly and change automatically.

It can start weld under the lowest voltage 120v, and the highest 380v will be not uploaded.

It uses the VRD function to forfend the electric shock under the damp environment.

80% of components are imported to insure that it can be up the design requirement.

It uses the proprietary main circuit protective cover.

Main Technical Parameter

Ten must-choose reasons

1. All the key components are imported from world-renowned brands,  so as to ensure that the products will not fail to meet the design requirements due to device reasons, and ensure that the product design life can reach more than 10 years.
2. The core control chip adopts the latest pulse width modulator, double closed-loop feedback control, more excellent static and dynamic characteristics, ensure more stable output, can meet the requirements of manufacturing welding refinement, and power factor up to 0.98, more environmental protection and energy saving.
3. The machine has a short circuit protection function and a unique standby working circuit, no damage to welding machine when no load, life can be extended more than twice.
4. The whole machine adopts full-bridge inverter main circuit structure, which has super anti-overload capacity and superior welding process, even though the output welding wire is 100 meters long ,it can still maintain stable welding.
5. In order to avoid the danger of electric shock caused by arc voltage under damp environment, the whole machine is designed according to the standard of three-proof, and adopts the function of anti-electric shock with patented technology.
6. All models adopt high frequency transformer with ultramicro magnetic core, which can effectively reduce the loss of high frequency transformer. The magnetic core is packaged with epoxy resin, with high mechanical strength, no hysteresis and expansion, and can withstand strong vibration, reduce the volume of switching power supply, and improve the reliability of the machine.
7. It has voltage fluctuation compensation circuit, could be highly adaptable to power supply network fluctuations.There will be small impact on the grid,and long service life.
8. The machine adopts the current and voltage double waveform control circuit, which can accurately control the current in the time range of microseconds. The improvement of control precision greatly improves the welding cutting accuracy, minimizes welding spatter, and makes welding seam forming more beautiful.
9. All products adopt digital display, current and voltage can be preset, easier to operate, more intuitive to see real-time welding data, more accurate for the adjustment of welding parameters.
10. Adopt patented ventilation and heat dissipation method to keep core components working together at the same temperature to prevent overload of some devices; At the same time, the unique IGBT self-locking protection circuit is adopted to ensure that the components are basically not damaged and increase the reliability of the product.
