# Classification
This welding equipment is divided into several specifications: by power source — AC and inverter DC; by welding wheel arrangement — horizontal and longitudinal; by quality grade — premium and basic. All are professional Seam Welding Machine models designed for industrial production.
# Features
1. A 3-phase variable-frequency motor is adopted, delivering stable welding speed, easy adjustment, and consistent running performance.
2. The welding circuit loop is cooled by internal water cooling, while the welding wheels (electrodes) use external water cooling.
3. The conductive rotating parts are structured with embedded silver bushings. The conductive base is sealed oil-lubricated and water-cooled to ensure flexible rotation and avoid locking.
4. This Automated Seam Welding System can be configured as horizontal (H) or longitudinal (L) to match different welding processes.
# Unique Strengths Compared with Other Welders
1. The embedded silver bushing design for conductive rotating parts, combined with sealed oil lubrication and water cooling, ensures smooth and durable rotation.
2. The rotating shaft inside the conductive base is treated with nanometer ceramic spraying, which offers higher wear resistance than conventional nylon, greatly extending service life.
3. Square cylinder guide bars are used instead of round ones, effectively preventing welding wheel deflection and improving overall welding quality.
# Machine Components
1. Machine body: Vertical reinforced structure, welded with high-quality thick steel plates for high rigidity.
2. Transformer: Made of 15000 gauss high-permeability silicon steel sheets with internal water cooling and full copper alloy core. It features low impedance, high power efficiency, 50% duty cycle for continuous welding, high output, long service life, low noise and compact layout.
3. Solenoid: Taiwan origin, high speed and reliable quality.
4. Cylinder: High-precision anti-friction hard duralumin, rustproof, low friction, low noise, fast pressure response, reducing welding spatter.
5. Welding wheels: Made of CuCrZr alloy with excellent wear resistance, water-cooled for longer service life.
