The IGBT inverter submerged arc welder is an integrated welding system. This inverter welder has the following functions: welding energy supply; continuous wire feeding; automatic movement of arc along weld; flux spreading in welding area; control of welding parameters and steps.

Our inverter submerged arc welder has many advantages, such as high productivity, excellent welding quality, and strong wind resistance. It is the most commonly used automatic arc welding method in industrial production. It is widely used in areas of shipbuilding, boilers, bridges, chemical containers, heavy machinery, metallurgy machinery and steel manufacturing, and other fields.

1. The inverter submerged arc welder adopts IGBT module with an inverter frequency of 20KHz. The key components include the fast recovery diode, integrated circuit, relay, current and voltage regulator. They all come from international famous brand with high reliability.

2. Soft switching inverter technology is employed by our designer. All the technical indicators have reached the industrial standard of international famous brands.

3. PWM wire feed control and arc voltage compensation create optimum welding condition.

4. Even in an ambient temperature of 40°C, the submerged arc welder still keeps a 100% duty cycle. It is particularly suitable for long time running in harsh environments, like the use under high temperature and high current circumstances in heavy industries.

5. The submerged welding machine has constant current, constant voltage output, and multifunctional power supply. It is suitable for electro-slag welding, air carbon arc gouging, submerged arc welding with fine wire (constant voltage), and submerged arc welding with thick wire (constant current).

6. At arcing point, the wire contacts with workpiece, and wire feed will automatically stop. Wire feeding head will not be lifted. The operation will be more convenient.

7. The system performs with a nearly 100% arcing success rate. The welding features strong penetrability and good-looking result.

8. The inverter control power supply only asks for 80% input capacity of a conventional welding machine. Thereby, the submerged arc welder has much lower power consumption.

9. The machine weight is 67% lighter than that of conventional welders, and the volume is 52% smaller. So the installation is quite easy.

10. This arc welding equipment has perfect protection circuit and automatic arc-retracting circuit to ensure safe operation.
