The Spot Welding Machine (Manual) is a versatile, user-operated device designed for joining metal surfaces through localized heat generated by electrical resistance. It is typically used for welding thin metal sheets in industries like automotive, electronics, and manufacturing. This manual machine requires the operator to apply pressure and control the welding process, allowing for precision in small-scale or intricate welding tasks. Equipped with adjustable settings for current and welding time, it offers flexibility for various metal types and thicknesses. Simple and cost-effective, the manual spot welding machine is ideal for small workshops or repair tasks requiring high-quality, reliable welds.

The Spot Welding Machine (Pneumatic) is an industrial-grade device designed for joining metal sheets using a localized electric current. It features a pneumatic system that automatically applies pressure, ensuring consistent and uniform welding results. This machine is ideal for applications where precision and speed are crucial, such as in the automotive and electronics industries. The pneumatic mechanism allows for quick and efficient operation, reducing operator fatigue and improving productivity. With adjustable welding time, pressure, and current settings, the spot welding machine offers flexibility for various materials and thicknesses, ensuring strong, reliable welds in a wide range of manufacturing processes.
