---
1. Utilizes inverter technology and IGBT dual modules for energy efficiency.
2. Transformers and reactors are all made with copper wire for better performance.
3. The actual input current matches the rated value for accurate performance.
4. Compact design, lightweight, high reliability, and excellent welding results.
5. OEM services are available for all products.
6. One-year warranty on the whole unit and PCB board, with 4% spare parts value provided for maintenance.
Features:
The MZ7 automatic submerged arc tractor and power source combine to form a complete automatic submerged arc welding system. It can be used for butt, lap, and corner joints in medium to thick steel structures. It is suitable for welding carbon steel, low alloy steel, stainless steel, and heat-resistant steel.
(1) Both front and rear wheels move simultaneously for stable movement and a wide welding range, supporting wire diameters from Ф3.0 to Ф6.0 mm.
(2) Easy adjustment with an integrated head and adjustable welding torch.
(3) The beam can rotate and lift for versatile operation.
(4) The flux container's turning and fluctuation angle can be adjusted for optimal performance.
(5) The wire feeder includes an alignment mechanism for smooth feeding, strong pulling force, and wide adjustment range.
(6) A print motor is used for both wire feeding and movement, ensuring low power consumption and long service life.
(7) Supports MMA and gouging welding.
(8) Built-in welding expert database allows saving 30 sets of custom parameters.
(9) All-digital LCD menu for easy operation and clear display of functions and data.
