Features
- Iron core of main transformer is ring-shaped. The coil is varnished wire added with Teflon belt for reinforced insulation. Therefore, this DC MMA welder with iron core can be used even in the low-temperature environment or humid environment.
- The AC welding machine is adapt to the environment temperature up to 45°C, 5°C higher than the national standard temperature +40°C. It works normally even in the outdoor environment.
- P plate has gone through the moisture-proof processing. The whole plate has been immersed in the rubber for 3 times. All the parts including surface welding point are protected by insulation film.
- The DC MMA welder applies the simplified main circuit design, as it has no AC contactor. The buffering circuit is changed from resistance capacity type to buffer capacitor, avoiding the IGBT damage caused by buffer circuit failure.
