Boost your sheet metal fabrication throughput with our Multi-Station Projection Spot Welder, engineered to deliver 8 completed projection welds in a single clamping motion. This machine is purpose-built for galvanized steel parts requiring repeatable, high-strength joints across automotive, appliance, and enclosure manufacturing lines. With independent pressure and current regulation per weld head, you gain precise control over each weld point without slowing down your cycle time.
As a manufacturer with a 20,000 m² facility and an in-house R&D team of over 20 engineers, we focus on building production-oriented welding equipment that minimizes operator intervention and maximizes consistency. Every unit is backed by overseas technical service teams in Southeast Asia and South America, ensuring on-site installation support and rapid response when you need it most.
Four welding heads, each completing 4 projection welds, deliver a total of 8 weld points per clamp. The automatic sequential firing—left to right—eliminates manual repositioning, reducing operator fatigue and boosting output per shift.
Welding pressure and current are independently adjustable for every head, allowing you to fine-tune each weld zone according to material thickness and coating conditions. Stroke adjustment minimizes idle travel, cutting cycle time and preventing interference between workpiece features.
The frame is shock-resistant, seismic-resistant, and internally reinforced with multiple ribs to minimize deformation during welding. This structural rigidity ensures stable electrode alignment weld after weld, while protecting the operator during prolonged production runs.
The upper electrode uses a gas-liquid pressure cylinder combined with an aluminum alloy barrel and low-damping seal ring. A pilot large-flow solenoid valve delivers extremely fast tapping speed and precise pressure follow-up, improving weld consistency on coated steel.
The upper electrode moves horizontally with independent welding stroke and workpiece operation stroke, while the lower electrode remains fixed. This simplifies operation, reduces pressure impact on parts, and lowers noise during the descent and ascent phases.
| Industry | Typical Workpiece | Welding Mode |
|---|---|---|
| Automotive Parts | Bracket assemblies, mounting plates | Multi-point projection welding |
| Home Appliances | Washer drums, oven panels | 8 welds per clamp sequence |
| Sheet Metal Fabrication | Galvanized steel enclosures, frames | Simultaneous multi-head welding |
| Electrical Cabinets | Mounting rails, hinge reinforcements | Sequential automatic firing |
| Furniture Manufacturing | Metal shelving, support brackets | Projection spot welding |
When the operator presses the start button, the welding controller automatically fires each head in sequence from left to right—no manual intervention required until all weld points are complete. Each head performs projection welding of 4 points, achieving 8 protrusions in one clamping process. Since every head has independent pressure and current adjustment, and the auxiliary cylinder position is tuned via the adjusting nut, you can reduce idle stroke and prevent interference between the workpiece and the electrodes for each unique part geometry.

The welding controller automatically fires each head from left to right once the start button is pressed. Each head's auxiliary position is adjusted using the adjusting nut on the auxiliary cylinder, and the stroke is set to minimize idle travel. This lets you adapt the sequence to different part shapes without additional programming.
Yes. The independent pressure and current regulation per head, combined with the fast-response gas-liquid cylinder, helps control heat input precisely. We recommend running a sample test with your specific material and coating thickness; our engineers can help you determine optimal parameters before full production.
For A3 steel, the capacity ranges from 2.5+2.5 mm on the DN-40 model up to 6+6 mm on the DN-200 model. For galvanized steel, the actual range depends on coating weight and part rigidity; share your drawing and we will confirm suitability.
The machine comes with a 1-year warranty covering core components. Free spare parts are provided as part of the package, and our overseas technical teams in Southeast Asia and South America are available for on-site installation, maintenance, and training.
The machine requires a 380V three-phase power supply (50/60 Hz), filtered compressed air, and cooling water at 2.5 bar. The integrated air storage tank helps stabilize welding pressure, while the cooling water system keeps temperature consistent during continuous operation.
