1. Digital operation interface and double knob operation can set welding parameters and operation functions more intuitively and diversifiedly.

2. Integrating all-digital dual CPU control technology and soft-switching IGBT inverter technology to achieve good welding performance.

3. By modifying and upgrading control software, we can quickly cope with the special welding procedure requirements of customers.4. Soft switching IGBT full bridge inverter technology, double closed loop current mode control (UC3846).5. Main transformer transformer adopts super microcrystalline iron core with inverter frequency as high as 20KH6. Passive power factor correction technology, high power factor. Input voltage range 320v-450v7. The control circuit adopts full digital computer control technology, which reduces the control circuit and greatly improves the reliability of the equipment.8. with overcurrent and overheating protection function, all digital current and voltage display of power supply and control box.9. The arc voltage compensation function can work normally in the unstable grid environment.10. Two ways of striking arc. Automatic return arc ignition circuit11. Both flat and falling characteristics are suitable for both thick and thin plates.12. Three use: arc welding, submerged arc welding and carbon arc gas gouging.13. The load duration is one hundred percent.14. Various submerged arc welding trolleys can be equipped with remote control and near control functions, reserved control interface and special equipment for automatic welding.
