This stationary spot welding machine is engineered for high-volume resistance welding of aluminum and steel workpieces in demanding fabrication environments. With a power range from 100 KVA to 250 KVA, the series provides scalable welding force and current output to match varying material thickness and production throughput requirements, making it a dependable asset for assembly lines and job shops alike.
Built with a rigid frame and precision-controlled electrode movement, the unit ensures consistent weld nugget formation and repeatable quality across batch production. Its compact stationary design simplifies installation, while the generous working stroke and adjustable electrode length offer flexibility for handling different part geometries. Factory-direct supply enables customization of transformer capacity, arm configuration, and control options to suit your specific application.
Maximum short-circuit current reaches up to 45 KA in the 250 KVA model, providing sufficient thermal input for sound weld joints on steel and aluminum sheets up to 6.0+6.0 mm combined thickness.
Electrode force ranges from 6000 N to 15000 N across the series, ensuring firm contact pressure that minimizes weld spatter and improves joint integrity even on high-strength material stacks.
An integrated water cooling system with a consumption rate of 20 L/min maintains stable electrode and transformer temperatures, allowing a 50% duty cycle without degradation in weld quality during extended shifts.
The standard 3-phase 380V AC input simplifies factory wiring and supports balanced load distribution, reducing energy cost per weld and accommodating a wide range of workshop power infrastructures.
With 450–500 mm electrode lengths and an 80 mm working stroke, the machine can accommodate varied part depths and clamp positions, offering adjustability that standard fixed-arm equipment often lacks.
Each unit undergoes staged inspection by our QC department before shipping, with machinery test reports available to verify performance parameters prior to delivery.
| Industry | Typical Workpiece | Welding Mode |
|---|---|---|
| Sheet Metal Fabrication | Steel enclosures and brackets | Spot welding |
| Automotive Components | Body panels and mounting plates | Projection / spot welding |
| Lighting and Appliance | Aluminum reflectors and frames | Spot welding |
| General Manufacturing | Mixed steel and aluminum assemblies | Multi-mode spot welding |
The machine operates on the resistance welding principle, where a low-voltage, high-current electrical path is passed through overlapping metal workpieces held under pressure between two copper electrodes. Electrical resistance at the interface generates localized heat that melts a confined zone, forming a solid weld nugget after the current is cut and the metal cools rapidly under maintained electrode force. The transformer converts the 380V three-phase input into a high-current welding circuit, while a water cooling loop dissipates excess heat to sustain continuous cycle operation.
