Gantry gate type H-beam welding machines are cost-effective and highly efficient, designed with extensive industry experience. They are capable of welding 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 uses an imported AC frequency converter to control both sides' synchronous speed adjustment, ensuring stable speed and accurate digital display of linear speed. It is equipped with a three-axis mechanical tracking guide arc device, where vertical movement is pneumatically tracked and horizontal movement is floating tracked, ensuring the welding torch accurately follows the weld seam. The submerge arc welding power setup is mounted on the gantry, moving along with it, which reduces cable length, minimizes voltage drop, and ensures stable welding performance. The welding control and gate frame control are integrated for easy operation. The cables in the welding arm are arranged in a drag chain, providing a neat and safe configuration.
**Key Features:**
1. Two structural types: Gantry gate move type and 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 functions as a mechanical tracker for up/down and left/right movements.
5. Imported frequency converter enables stepless speed adjustment, offering a wide range, high precision, and constant torque output.
6. Electrical control cabinet includes a main control unit and remote operation box.
7. Capable of welding two workpieces at once.
**Supply Scope:**
1. Gantry gate unit: Gantry, travel device, lateral sliding device, wire feeding wheel, and pipe accessories.
2. Welding arm and carriage: Welding arm, motor transmission device, moving mechanism, and accessories (two sets).
3. Arc guide device: Welding gun, mechanical adjustment unit, and wire feeding machine (two sets).
4. Flux recovery system: 100kg flux recovery machine, separate material barrel, flux hopper, and flux recovery and transport pipes.
5. Electric control system: Control cabinet, AC frequency converter, operation box, lighting, and warning lights.
6. Pipe and wire system: Power cables, control wires, welding cables, gantry control cables, air source pipes, and suspension sliding frames.
7. Welding system: MZ-1000 submerge arc welding machine (two sets).
