# Classification
This series is categorized by power supply into AC and inverter DC types; by welding wheel orientation into horizontal and longitudinal types; and by performance grade into premium and standard versions, representing a professional
Seam Welding Machine solution.
# Features
1. A 3-phase variable-frequency drive motor is employed, providing steady welding speed, simple parameter tuning, and consistent operational stability.
2. The welding circuit loop is cooled via internal water circulation, while the welding wheels (electrodes) use external water cooling.
3. Conductive rotating components are designed with embedded silver bushings. The conductive base is sealed oil-lubricated and water-cooled to maintain flexible rotation and prevent seizure.
4. Offered in both horizontal and longitudinal configurations, this
Automated Seam Welding System is marked as H for horizontal and L for longitudinal.
# Key Competitive Strengths
1. The embedded silver bushing structure for conductive rotating parts, paired with sealed oil lubrication and water cooling, ensures smooth and reliable rotation without locking.
2. The rotating shaft inside the conductive base features nanometer ceramic spraying, delivering superior wear resistance over conventional nylon materials and extending service life.
3. Square cylinder guide bars are used instead of round ones, minimizing welding wheel deflection and resulting in higher and more consistent welding quality.
# Machine Components
1. Machine body: Constructed with vertical reinforcement and welded from heavy-duty high-quality steel plates.
2. Transformer: Built with 15000 gauss high-permeability silicon steel sheets, internally water-cooled, with a full copper alloy core to lower impedance and enhance power efficiency. It supports 50% duty cycle for continuous welding, offers high output, long service life, low noise, and a compact layout.
3. Solenoid: Sourced from Taiwan, featuring high speed and reliable performance.
4. Cylinder: Made of high-precision wear-resistant hard duralumin, rust-free, low friction, low noise, and rapid pressure response, effectively reducing welding spatter.
5. Welding wheels: Manufactured from CuCrZr alloy with high wear resistance, water-cooled for extended durability.
