# Classification
This roller seam welding machine is classified according to multiple criteria: By power source: AC type and inverter DC type
By welding wheel arrangement: Horizontal and longitudinal
By quality grade: Premium grade and standard type
# Features
1. It adopts a 3-phase variable frequency motor, which ensures stable and uniform welding speed, convenient adjustment and reliable running performance.
2. The welding circuit loop is cooled by internal water circulation, while the welding wheels (electrodes) adopt external water cooling.
3. The conductive rotating parts on the welder adopt an embedded silver bushing structure. The conductive base is sealed oil-lubricated and water-cooled, allowing the silver bushings to rotate flexibly without locking.
4. This Automated Seam Welding System supports both horizontal and longitudinal operation modes, marked as H for horizontal and L for longitudinal.
# Main Advantages Over Other Models
1. The conductive rotating components are designed with embedded silver bushings. The conductive base is sealed oil-lubricated and water-cooled to maintain smooth rotation and prevent seizure.
2. The rotating shaft inside the conductive base is treated with nanometer ceramic spraying, instead of conventional nylon material, providing higher wear resistance and longer service life.
3. The cylinder guide bar adopts a square structure rather than a round one, which effectively prevents the welding wheel from skewing and ensures better welding quality.
# Machine Composition
1. Machine body: Built with vertical reinforced structure, welded with high-quality thick steel plates.
2. Transformer: Made of silicon steel sheets with 15000 gauss magnetic permeability, equipped with internal cooling water and full copper alloy core. It features low impedance, high power utilization, 50% duty cycle for long-time welding, high output power, longer service life, lower noise and more compact structure.
3. Solenoid: Imported from Taiwan, with high speed and reliable quality.
4. Cylinder: Made of high-precision wear-resistant hard duralumin, rust-proof, low friction, low noise and fast pressure application, thus reducing welding spatter.
5. Welding wheels: Made of CuCrZr material with excellent wear resistance, water-cooled for extended service life.
