Product Description

Pneumatic Stationary Spot Welding Machine 200KVA 380V for Nuts Bolts

Video Demonstration

Product Overview

The D(T)N Series Pneumatic Stationary Spot Welding Machine delivers 200KVA welding power with 380V input, purpose-built for high-volume nut and bolt welding applications in industrial manufacturing environments. This stationary spot welder combines robust construction with micro-computer control to ensure consistent, repeatable weld quality across production shifts.

Engineered for the automotive, hardware fabrication, and appliance manufacturing sectors, this projection spot welding machine handles steel sheets up to 6+6mm thickness with electrode force reaching 12000N. The integrated air-assisted stroke system accelerates production cycles while maintaining precise pressure control, making it a reliable choice for continuous-duty welding operations requiring both speed and accuracy.

Key Technical Advantages

Rigid Frame with Pneumatic Pressure System

The stable machine structure applies pressure through the electrodes using an auxiliary stroke mechanism, ensuring uniform clamping force on every weld. This design delivers higher welding efficiency and reduces workpiece deformation, directly improving weld consistency across large production batches.

High-Efficiency Water-Cooled Transformer

The dedicated resistance welding transformer features high-permeability silicon steel laminations with forced internal water cooling. This construction provides stronger welding power and a high duty cycle rating of 50%, enabling sustained operation without overheating—critical for continuous production environments.

Micro-Computer Control with 16 Program Storage

The micro-computer control system stores up to 16 independent welding settings, allowing operators to switch between different workpiece configurations instantly. This reduces setup time between product changeovers and ensures parameter consistency that maintains weld quality across varying material thicknesses.

High Welding Capacity with Deep Throat Design

With a maximum welding capacity of 6+6mm and a generous 630mm throat depth, this machine accommodates large workpieces and facilitates easy access to weld joints. The 200KVA rated power delivers up to 34KA short-circuit current, providing the thermal energy needed for secure nut and bolt projections welds.

Adjustable Electrode Force up to 12000N

The pneumatic system delivers adjustable electrode force up to 12000N, ensuring proper forging pressure for solid nugget formation on medium-thickness carbon steel. This capability reduces weld expulsion and porosity, lowering rework rates and consumable electrode wear over extended production runs.

Applications

Industry	Typical Workpiece	Welding Mode
Automobile Manufacturing	Nuts, bolts, brackets, sheet metal panels	Projection welding / Spot welding
Home Appliance Production	Enclosures, mounting plates, handles	Spot welding / Projection welding
Hardware & Fittings	Fasteners, hinges, connectors	Projection welding
Machinery Repair Shops	Worn components, frame assemblies	Spot welding
Construction Works	Steel structures, reinforcement meshes	Spot welding

Working Principle

The D(T)N Series stationary spot welding machine operates on the resistance welding principle, where heat is generated by electrical current passing through the contact resistance between two workpieces. The pneumatic cylinder lowers the upper electrode to clamp the workpieces with preset force, then the welding transformer delivers a controlled high-current, low-voltage pulse through the electrodes. The localized resistance heating melts the material at the faying surface, forming a molten nugget that solidifies under continued electrode pressure to create a strong metallurgical bond. The micro-computer controller regulates weld current, time, and electrode pressure sequence, while the internal water-cooling circuit maintains transformer and electrode temperatures within optimal range for consistent weld quality.
