# Classification
Our product line is classified by power source: AC and inverter DC; by welding wheel orientation: horizontal and longitudinal; and by quality grade: premium and standard. All these variants belong to the professional Seam Welding Machine series.
# Features
1. A 3-phase variable frequency motor is adopted, ensuring stable welding speed, easy adjustment, and reliable operation.
2. The welding circuit loop is cooled by internal water cooling, while the welding wheels (electrodes) adopt external water cooling.
3. The conductive rotating parts are designed with embedded silver bushings. The conductive base is sealed oil-lubricated and water-cooled to ensure flexible rotation without locking.
4. This
Automated Seam Welding System is available in horizontal (H) and longitudinal (L) types to meet different welding requirements.
# Main Advantages Over Other Welding Equipment
1. The conductive rotating parts feature embedded silver bushings, with sealed oil lubrication and water cooling on the conductive base, ensuring smooth rotation and preventing seizure.
2. The rotating shaft inside the conductive base uses nanometer ceramic spraying instead of ordinary nylon, providing higher wear resistance and longer service life.
3. The cylinder guide bar is square instead of round, which prevents the welding wheel from skewing and ensures better welding quality.
# Machine Composition
1. Machine body: Vertical reinforced structure, welded with high-quality thick steel plates.
2. Transformer: Made of 15000 gauss high-permeability silicon steel sheets, with internal water cooling and full copper alloy core, low impedance, high power utilization, 50% duty cycle for long-time welding, high output power, long service life, low noise and compact structure.
3. Solenoid: From Taiwan, high speed and reliable quality.
4. Cylinder: Made of high-precision anti-friction hard duralumin, rust-proof, low friction, low noise and fast pressure application, reducing welding spatter.
5. Welding wheels: Made of CuCrZr material with high wear resistance, water-cooled for longer service life.
