Industrial Single Phase 220V Pneumatic Projection Resistance Welder 50KVA

Single Phase Pneumatic Projection Resistance Welder for Fuel Tank Gas Caps

This industrial single phase pneumatic projection resistance welder is engineered for high volume fuel tank and gas cap production. With a rated capacity range of 40-250 KVA and a maximum welding thickness of 6+6 mm, it delivers dependable resistance welding power while operating from a standard 220V single phase supply. The stainless steel body and pneumatic actuation are designed to keep cycle times short and weld quality consistent in continuous production environments.

Built for precision and repeatability, the machine converts electrical energy into targeted heat at the projection points between sheet metal components. Its 50% duty cycle supports sustained operation in demanding manufacturing shifts, while the pneumatic system provides controlled pressure for uniform weld nuggets. As a result, manufacturers gain higher throughput, lower per part cost, and reliable joint strength for fuel tanks, gas caps, and other formed metal assemblies.

Key Technical Advantages

Pneumatic Actuation for Fast Repeatable Welds

The pneumatically controlled electrode movement ensures consistent clamping force and rapid cycle times. Operators can maintain high output with minimal physical effort, and the repeatable pressure helps produce uniform weld nuggets across large production batches.

High Welding Capacity for Heavy Duty Fabrication

With a 40-250 KVA rated capacity and 6+6 mm maximum welding thickness, this projection welder handles a wide range of sheet metal and projection welding applications. It gives production lines the power to join thicker fuel tank components and mounting brackets without compromising cycle speed.

Single Phase 220V Installation Convenience

Designed to operate on single phase 220V power, the machine reduces installation complexity in workshops where three phase supply is unavailable. This lowers setup cost and makes it a practical choice for small and mid sized fabrication facilities.

Rugged Stainless Steel Construction

The stainless steel frame and enclosure resist corrosion, weld spatter, and daily workshop wear. This extends service life, reduces maintenance downtime, and keeps the machine presentable for inspections and factory audits.

Frequently Asked Questions

What is the maximum welding thickness of this machine?

The machine can weld up to 6+6 mm combined thickness in projection resistance welding applications, depending on material type and the shape of the projections.

Does the welder run on three phase power?

No. This model is designed for single phase 220V input, making it easier to install in workshops without a three phase power supply.

What duty cycle does the machine support?

The rated duty cycle is 50%, which allows sustained production use while giving the transformer time to cool between weld cycles.
