# Classification
Categorized by power source: AC and inverter DC
Categorized by welding wheel direction: horizontal and longitudinal
Categorized by quality grade: top quality and simple type
All above are standard models of the professional Seam Welding Machine.
# Features
1. Adopts 3-phase variable frequency motor to realize stable welding speed, convenient adjustment and reliable operation.
2. The welding circuit loop adopts internal water cooling, and the welding wheels (electrodes) adopt external water cooling.
3. The conductive rotating parts adopt embedded silver bushings, and the conductive base is sealed oil-lubricated and water-cooled to keep flexible rotation and avoid locking.
4. This Automated Seam Welding System can be customized into horizontal (H) and longitudinal (L) types for different working conditions.
# Core Advantages
1. The unique embedded silver bushing structure of conductive rotating parts, with sealed oil lubrication and water cooling, ensures stable and long-term rotation.
2. The rotating shaft in the conductive base is treated with nanometer ceramic spraying, which has stronger wear resistance than ordinary nylon and prolongs service life.
3. Square cylinder guide bar is adopted instead of round type, which effectively prevents welding wheel deflection and ensures more stable welding quality.
# Machine Composition
1. Machine body: vertical reinforced structure, welded with high-quality thick steel plate.
