# Classification
This series is grouped by power source into AC and inverter DC; by welding wheel direction into horizontal and longitudinal; and by quality level into premium and basic models, all as part of our professional Seam Welding Machine range.
# Features
1. Built with a 3-phase variable frequency motor, it delivers stable welding speed, simple adjustment, and consistent running performance.
2. The welding circuit loop uses internal water cooling, while the welding wheels (electrodes) are cooled externally.
3. Conductive rotating parts are designed with embedded silver bushings. The conductive base is sealed oil-lubricated and water-cooled to keep the bushings turning flexibly and avoid locking.
4. This
Automated Seam Welding System is available in horizontal (H) and longitudinal (L) versions to suit different production needs.
# Key Advantages Over Other Welders
1. The embedded silver bushing structure in conductive rotating parts, combined with sealed oil lubrication and water cooling, ensures smooth and reliable rotation.
2. The rotating shaft in the conductive base uses nanometer ceramic spraying instead of standard nylon, greatly improving wear resistance and extending service life.
3. Square cylinder guide bars replace the typical round type, preventing welding wheel deflection and delivering more stable welding quality.
# Machine Construction
1. Machine body: Vertical reinforced structure, welded with high-quality thick steel plate.
2. Transformer: Made with 15000 gauss high-permeability silicon steel sheets, internally water-cooled, full copper alloy core, low impedance, high power efficiency, 50% duty cycle for long welding runs, high output, long service life, low noise, and compact design.
3. Solenoid: Taiwan-made, high speed and reliable quality.
4. Cylinder: High-precision anti-friction hard duralumin, rustproof, low friction, low noise, fast pressure buildup, reducing welding spatter.
5. Welding wheels: CuCrZr material with high wear resistance, water-cooled for longer service life.
