This stationary AC projection welder is purpose-built for high-volume welding of metal rings onto fuel tank filler necks. By synchronously energizing seven fixed convex points, the machine produces seven consistent weld nuggets in a single cycle, delivering both speed and repeatability for demanding production lines.
Designed for manufacturers seeking a dependable, low-operator-skill solution, the unit supports automatic welding cycles with manual load/unload only. Its quick-change annular electrode system accommodates various tank diameters, while forced water cooling and multi-level electrical protection sustain stable output during continuous operation—an economical upgrade for fuel tank production capabilities.
Upper and lower electrodes press the metal ring against the tank shell, energizing seven fixed projections at once. This creates seven uniform welds per cycle, reducing cycle time and improving joint consistency compared to single-point methods.
The one-piece annular electrode ring can be swapped rapidly to suit different fuel tank orifice diameters. One machine handles multiple product specifications, blending the throughput of dedicated tooling with the flexibility of general-purpose equipment.
Once parts are loaded, the welding sequence runs automatically with standardized output. This lowers the operator skill barrier and maintains batch-to-batch consistency without dependence on experienced welders.
An internal forced-water cooling circuit keeps electrode and transformer temperatures stable during sustained full-load operation, extending electrode life and preserving welding energy output over long shifts.
A built-in gas reservoir minimizes welding pressure fluctuation, ensuring a stable electrode force through every cycle. This contributes to consistent weld penetration and reduced spatter.
| Industry | Typical Workpiece | Welding Mode |
|---|---|---|
| Fuel Tank Manufacturing | Fuel tank shell + metal filler ring | Multi-point projection welding |
| Automotive Components | Filler neck assemblies, brackets | Spot / projection welding |
| Metal Fabrication | Sheet metal with pre-formed projections | Resistance projection welding |
The fuel tank shell is placed on the lower electrode platform while the metal ring is held by the upper electrode. After vertical alignment, the upper and lower annular electrodes close, pressing seven fixed convex points against the workpiece. A high-current AC pulse is applied simultaneously at all seven points, generating localized resistance heat that fuses the ring to the tank inner wall. The entire weld sequence is automated, with operator involvement limited to loading and unloading parts.

The machine is designed primarily for mild steel (A3) fuel tank shells and metal rings. With appropriate electrode and parameter adjustment, it can also weld aluminum and stainless steel components on a case-by-case basis.
Each cycle produces seven weld points simultaneously, thanks to the fixed convex point annular electrode assembly. The upper and lower electrodes press together and energize all seven projections in one operation.
Yes. The annular electrode ring features an overall quick-change design, allowing operators to swap rings to accommodate different fuel tank orifice sizes. This gives one machine the ability to handle multiple product specifications.
Forced water cooling is mandatory for continuous operation. Cooling water consumption ranges from 6 to 10 L/min at 2.5 bar depending on the model, ensuring stable thermal performance during full-load production.
