Here is the rewritten and improved English version of your content, with additional details to make it more natural and comprehensive:
---
1. Utilizes inverter technology with IGBT dual modules for energy efficiency.
2. Reactors and transformers are all wound with copper wire for better performance and durability.
3. The actual input current matches the specified value, ensuring accurate performance.
4. Compact design, lightweight, high reliability, and excellent welding results.
5. All products support OEM customization.
6. Warranty: One year for the entire unit and PCB board. We also provide spare parts valued at 4% of the total order for maintenance purposes.
Features:
The MZ7 automatic submerged arc tractor and power source together form an automatic submerged arc welding system, suitable for butt joints, lap joints, and corner joints in medium-to-thick steel structures. It can weld various materials such as carbon steel, low alloy steel, stainless steel, and heat-resistant steel.
(1) Both front and rear wheels of the tractor move simultaneously, ensuring stable operation and a wide welding range, with wire diameters ranging from Ф3.0 to Ф6.0 mm.
(2) Easy to adjust, with an integrated head and adjustable welding torch.
(3) The beam can rotate and lift for flexible positioning.
(4) The flux container’s turning and fluctuation angle can be adjusted for optimal welding conditions.
(5) The wire feeding mechanism features an alignment structure for stable wire feeding, good adjustment range, strong pulling force, and efficient performance.
(6) A print motor is used for both wire feeding and movement, offering low power consumption and long service life compared to traditional motors.
(7) Supports MMA and gouging welding processes.
