Product name: New Pneumatic 100Kva Aluminum Stainless Steel Industrial Spot Welder Projection Welding Machine CE Certified
Pneumatic 100Kva Aluminum Stainless Steel Cookware Industrial Spot Welder Projection Welding Machine
This 100KVA Pneumatic Stationary Spot Welding Machine is a high-efficiency, versatile industrial welder designed for sheet metal joining. It can be used for projection welding, spot welding, and combination welding based on process requirements. The machine employs pneumatic pressurization with a vertically moving upper electrode, characterized by a compact structure, stable performance, safe and reliable operation, high efficiency, and energy savings. Its “fixed machine, moving workpiece” operation mode is particularly suitable for high-throughput welding of materials like low-carbon steel, coated steel plates, stainless steel, and aluminum plates in production lines. Models with projection welding capability can also weld standard parts and components. The typical weldable thickness range for carbon steel is 0.5+0.5mm to 6+6mm (according to specific spot welding specifications). It is widely used in industries such as automotive, aviation, machinery, construction, cabinet making, metal products, and household appliances.

Multi-Function Welding Modes
Integrates projection welding, spot welding, and combination welding functions in one machine. Users can flexibly select the mode based on workpiece geometry (e.g., projection welding for nuts/bolts, or lap spot welding for sheets), offering great adaptability.
Pneumatic Drive & Stable Construction
Utilizes a pneumatic pressurization system with a vertically moving electrode, delivering stable force output and fast response. The overall structure is compact and robust, ensuring smooth operation and consistent, reliable welding results.
Broad Material Compatibility
Designed for welding a variety of metals, it efficiently handles low-carbon steel, coated steel plates, stainless steel, and aluminum plates, meeting the manufacturing needs of diverse products like cookware, hardware, and structural components.
High Efficiency & Energy Saving
The high-capacity (100KVA) transformer operates with high efficiency. Coupled with optimized electrical controls, it is more energy-efficient than traditional AC welders. Its high duty cycle supports high-volume production.
“Moving Workpiece” Operation
Employs a “fixed machine, moving workpiece” operation method, making it ideal for fast, repetitive welding tasks on assembly lines or at workstations, thereby enhancing overall production efficiency
