Sheet Metal 380V 220V Projection Spot Welding Machine Customized Size

The DTN Series Stationary Spot & Projection Welding Machine is a classic, versatile resistance welding solution from our production line. Its core design integrates both spot welding​ and projection welding​ processes, primarily intended for welding sheets of low-carbon steel, stainless steel, and various non-ferrous metals. This series efficiently performs lap welding between sheets and reliable projection welding​ connections between sheets and fasteners like nuts and bolts. Renowned for its stable performance and broad applicability, it serves as a universal welding solution across numerous manufacturing sectors.

• Convenient & Precise Pneumatic System

  The upper electrode is pressurized by an air cylinder, allowing for convenient and precise force adjustment. A dedicated air reservoir helps buffer supply fluctuations, ensuring stable and consistent​ pressure output for every weld.

• Flexible & Adjustable Electrode Stroke

  The upper electrode moves vertically with smoothly and infinitely adjustable working​ and auxiliary strokes. The lower electrode is vertically adjustable in height​ for quick adaptation to workpieces of varying thicknesses and geometries.

• High-Efficiency Response & Energy Saving

  A direct-acting solenoid valve​ is employed, significantly improving system response time and electrode cycling speed, while optimizing the air circuit to effectively reduce air consumption​ for more economical operation.

• Adjustable Cushioning & Low-Noise Operation

  The descent and ascent speeds of the pressure head are independently and infinitely adjustable. This feature effectively cushions mechanical impact on the workpiece, protects surfaces, and notably reduces operational noise.

• Safe & Reliable Insulation Design

  The secondary circuit utilizes an upper insulation configuration, providing stable and reliable​ insulation. This design permits safe operation in various installation setups, simplifies mounting, and prevents short-circuit risks.

• Powerful & Stable Welding Power Source

  The main circuit incorporates a water-cooled, high-power thyristor rectifier module. Combined with efficient cooling, it ensures welding current output that is strong, stable, and reliable, supporting continuous, high-duty-cycle operation.

• Durable & Visual Cooling System

  All waterway components are made of copper and stainless steel​ for excellent corrosion resistance. A visual flow indicator​ allows for clear monitoring of coolant circulation, facilitating routine maintenance.

• Efficient & Ergonomic Operation

  Controlled via a foot switch, the welding cycle is fast, achieving high production efficiency​ while significantly reducing operator labor intensity.
