ChengDu Xinweihan is a leading welding equipment manufacturer in China, specializing in delivering complete welding solutions for global manufacturers. This pneumatic projection spot welding machine is engineered with a rigid high-strength frame, precision gas-liquid pressure cylinder, and independent welding head controls, ensuring stable and repeatable weld quality for sheet metal fabrication. Built to handle large workpieces with up to 8 projection welds per clamping cycle, it dramatically boosts throughput while maintaining consistent pressure and current at every weld point.
With a rated power range from 40 to 200 KVA and support for 220V/380V input, this versatile welder suits medium to heavy steel, copper, and aluminum applications. The horizontal electrode movement enables easy access to transverse weld points, making it ideal for assembly lines where installation space is limited. Our 20,000 sq.m facility and 20+ engineer R&D team back every machine with professional guidance and responsive after-sales support, including optional overseas technical service teams in Southeast Asia and South America.
The body is finely machined with multiple internal reinforcing ribs to deliver exceptional stiffness and minimal deformation under heavy loads, ensuring stable welding and safe manual operation during continuous production.
Each welding head allows separate adjustment of welding pressure and current, enabling precise tuning for varied workpiece thicknesses. The horizontal forward/backward movement of the upper electrode and fixed lower electrode simplify operation while expanding weld point accessibility.
A backup air storage tank minimizes welding pressure fluctuation, ensuring a stable and consistent welding force. The combination cylinder with low-damping seals and a pilot large-flow solenoid valve delivers rapid response and extremely sensitive follow-up performance for high-speed tapping.
The descent and ascent speed of the pressure head can be freely adjusted, softening impact on workpieces and lowering operational noise. Independent welding stroke and workpiece movement stroke further improve control and ergonomics.
Designed with eco-friendly operation in mind, the machine optimizes power usage while maintaining high weld quality. The fully automatic welding controller sequences all actions from start to finish, reducing manual intervention and improving energy efficiency.
| Industry | Typical Workpiece | Welding Mode |
|---|---|---|
| Manufacturing Plant | Sheet metal panels and brackets | Projection Spot Welding |
| Machinery Repair Shops | Reinforcement plates and frames | Multi-point Projection Welding |
| Construction Works | Steel studs and connectors | Spot Welding on Large Workpieces |
| Building Material Shops | Metal sheets and profiles | Transverse Point Welding |
When the start button is pressed, the welding cylinder sequentially moves from left to right, and the welding controller fully automates the entire equipment action until all weld points are completed—no manual intervention required. Each welding head performs projection welding on 4 points, yielding 8 protrusions welded in a single clamping operation, which consistently secures the quality of every individual weld. The pneumatic system drives the upper electrode with adjustable pressure, while the transformer delivers precise welding current, enabling efficient and repeatable joining of steel, copper, and aluminum sheets.

This machine is suitable for spot and projection welding of steel, copper, and aluminum sheets. It handles A3 steel up to 6+6 mm thickness effectively, making it versatile for a wide range of metal fabrication tasks.
Each welding head completes projection welding on 4 weld points, and with the full machine setup, a total of 8 protrusions are welded in a single clamping operation. This reduces handling time and significantly improves production efficiency.
Yes, the welding pressure and welding current for each head are independently adjustable. This allows precise control for different workpiece thicknesses and material types, ensuring consistent weld quality across every point.
