Gantry gate type H-beam welding machines are cost-effective and highly efficient, designed with extensive industry experience. They can weld two H-beam workpieces simultaneously, making them ideal for high-volume production environments.
**Introduction:**
This welding machine features a simple and reliable structure with a smart layout. The main transmission system utilizes an imported AC frequency converter to control the synchronized speed adjustment of both sides, ensuring stable performance and accurate digital display of linear speed. A three-axis mechanical tracking guide arc device is included, with pneumatic tracking for vertical movement and floating tracking for horizontal movement, ensuring the welding torch remains precisely aligned with the weld seam. The submerge arc welding power unit is mounted on the gantry gate, moving along with it, which reduces cable length, minimizes voltage drop, and ensures stable welding current. The welding control and gate frame control systems are integrated for ease of operation, and the cables in the welding arm are housed in a drag chain for safety and neatness.
**Key Features:**
1. Two structural options: Gantry gate move type or double cantilever move type.
2. Drive method: AC motor with R series worm reducer.
3. Welding speed: 0.15–1.5 m/min.
4. Arc guide frame head enables mechanical tracking in all directions.
5. Imported frequency converter allows stepless speed adjustment with wide range, high accuracy, and constant torque output.
6. Electrical control cabinet includes a main control panel and remote operation box.
7. Capable of welding two workpieces at once.
