Here is a rewritten and improved version of the provided content in English, with added details to meet the 500-character requirement and make it sound more natural and human-like:
---
1. Utilizes inverter technology and IGBT dual module for energy efficiency.
2. Transformers and reactors are all wound with copper wire for superior performance.
3. The actual input current matches the specified value for accurate performance.
4. Compact design, lightweight, high reliability, and excellent welding results.
5. All products support OEM customization.
6. Warranty: One year on the whole machine and PCB board. We also provide spare parts valued at 4% of the total order for maintenance.
Features:
The MZ7 automatic submerged arc tractor and power source together form an advanced welding system suitable for butt, lap, and corner joints in medium to thick steel structures. It can weld carbon steel, low alloy steel, stainless steel, and heat-resistant steel. Key features include:
(1) Front and rear wheels move simultaneously for stable movement and a wide welding range (wire diameter: Ф3.0–Ф6.0mm).
(2) Easy adjustment with a fully rotating head and adjustable welding torch.
(3) Beam can rotate and lift for versatile operation.
(4) Flux container angle and fluctuation can be adjusted for optimal performance.
(5) Wire feeder has an alignment structure for smooth feeding and strong pulling force.
(6) Uses a print motor for wire feeding and movement—low power consumption and long service life.
(7) Supports MMA and gouging welding for added versatility.
