Cnc Fan Guard Dc Spotwelding Soldadura Por Punto Fixed Type Spot Welding Machine for Stainless Steel
Product name: Cnc Fan Guard Dc Spotwelding Soldadura Por Punto Fixed Type Spot Welding Machine for Stainless Steela
This Fixed Type Projection Spot Welding Machine is optimized for joining precision components post-CNC machining, such as stainless steel fan guards. Utilizing a Direct Current (DC) welding power source, it offers concentrated heat input and minimal spatter, making it particularly suitable for high-quality welding of stainless steel, low-carbon steel, aluminum alloy plates, and some non-ferrous metals. It also reliably performs projection welding between sheets, and between sheets and nuts or bolts.

High-Precision Pneumatic Control: The upper electrode is driven by a high-precision air cylinder, allowing for convenient and accurate pressure adjustment to ensure consistent welding force. A dedicated air reservoir is included to buffer supply fluctuations, guaranteeing stable weld quality.
Flexible & Adjustable Stroke System: The upper electrode features vertical movement with smooth, independent, and infinitely adjustable working and auxiliary strokes. The lower electrode allows for fine vertical height adjustment, enabling quick adaptation to workpieces of different specifications.
Rapid Response & Energy Efficiency: Employs a direct-acting, high-flow solenoid valve, significantly improving system response time and the cycling speed of the upper electrode. Its optimized aerodynamic design also reduces compressed air consumption.
Cushioned Motion & Low-Noise Operation: Both the descent and ascent speeds of the pressure head are independently and infinitely adjustable. This effectively cushions mechanical impact on the workpiece, protects surfaces, and markedly reduces operational noise.
Stable & Reliable Electrical Insulation: The secondary circuit employs an upper insulation configuration, providing stable and reliable insulation performance. This effectively prevents short-circuit risks and enhances equipment safety and adaptability in diverse working conditions.
High-Power Water-Cooled Source: The main circuit utilizes a high-power thyristor rectifier module coupled with an efficient water-cooling system. This ensures robust, stable, and reliable power output even under high-current, continuous operation.
Durable Cooling & Monitoring System: All critical waterway components are constructed from corrosion-resistant copper or stainless steel for longevity. An integrated visual flow indicator allows for real-time monitoring of coolant status, simplifying maintenance.
Efficient & Ergonomic Operation: Controlled via a standard foot switch, it supports ergonomic single-operator, multi-machine workflows. This design ensures high productivity and consistent welding cycles while significantly reducing operator fatigue.
