# Classification
Divided by power source: AC and inverter DC
Divided by welding wheel direction: horizontal and longitudinal
Divided by quality grade: top quality and simple type
The above models all belong to the professional Seam Welding Machine product series.
# Features
1. The machine is driven by a 3-phase variable-frequency motor, which guarantees stable welding speed, convenient parameter adjustment and reliable operation.
2. Internal water cooling is adopted for the welding circuit loop, and the welding wheels (electrodes) are cooled by external water circulation.
3. The conductive rotating components are designed with embedded silver bushings. The conductive base is lubricated with sealed oil and cooled by water, so that the silver bushings can rotate flexibly without locking.
4. This Automated Seam Welding System can be provided in two types: horizontal (H) and longitudinal (L), to meet different welding process demands.
# Main Competitive Advantages
1. The conductive rotating parts adopt embedded silver bushing structure, and the conductive base is equipped with sealed oil lubrication and water cooling, which ensures flexible rotation and avoids seizing.
2. The rotating shaft inside the conductive base is processed with nanometer ceramic spraying, which is more wear-resistant than traditional nylon materials, thus prolonging the service life of the machine.
3. The cylinder guide bar adopts a square structure instead of a round one, which effectively prevents the welding wheel from skewing and ensures better welding quality.
# Machine Constitution
1. Machine body: adopts vertical reinforced structure, welded with high-quality thick steel plates.
2. Transformer: stacked with silicon steel sheets of 15000 gauss permeability, with internal cooling water and full copper alloy core, which reduces impedance, improves power utilization, supports 50% duty cycle for long-time welding with large output power, and features longer service life, lower noise and more compact structure.
3. Solenoid: imported from Taiwan, with high speed and reliable quality.
4. Cylinder: made of high-precision anti-friction hard duralumin, rust-proof, low friction, low noise and fast pressure-adding, thus reducing welding spatter.
5. Welding wheels: made of CuCrZr material with excellent wear resistance, and cooled by water for longer service life.
