Pneumatic Pulse Energy Storage Spot Welder

Product Overview

The FH-149A represents a specialized category of resistance welding equipment that utilizes stored electrical energy to generate precise, high-current pulses for spot welding applications. Unlike conventional continuous-current spot welders, this pneumatic pulse system discharges energy from capacitors in controlled bursts, delivering concentrated heat exactly where it is needed while minimizing thermal distortion to surrounding materials.

Designed with pneumatic actuation, the machine applies consistent electrode pressure automatically, ensuring uniform weld nugget formation across every production cycle. The combination of energy storage technology and pneumatic pressure control results in repeatable, high-quality welds that meet the stringent demands of heating tube manufacturing.

Key Advantages

The Pneumatic Pulse Energy Storage Spot Welder from Feihong incorporates several design and performance benefits that set it apart for heating tube production applications:

1. High Production Efficiency: Capable of processing 30,000 pieces within an 8-hour shift, significantly boosting manufacturing throughput and reducing per-unit production time.

2. Precise Energy Control: Capacitor voltage adjustable from 0 to 435V, allowing operators to fine-tune welding energy for different material thicknesses and types.

3. Pneumatic Operation: Automated pneumatic electrode pressure delivery ensures consistent force application across all welds, eliminating variability caused by manual operation.

4. Flexible Voltage Compatibility: Supports three-phase 380V, three-phase 220V, and single-phase 220V input configurations to accommodate different factory power supply standards worldwide.

5. User-Friendly Design: Intuitive operation interface and straightforward controls reduce training time and enable quick integration into existing production lines.

Technical Specifications

The FH-149A model is built with carefully engineered electrical and mechanical parameters to deliver reliable performance in industrial production environments. Below are the core technical specifications:

With a rated power of 2 KVA, the machine balances sufficient welding capability with energy efficiency, making it suitable for both small-scale workshops and large-scale heating tube manufacturing facilities.

Application Fields

The Pneumatic Pulse Energy Storage Spot Welder finds its primary application in the electrical heating tube manufacturing industry, where reliable joining of internal components is critical to product performance and service life.

Heating Tube Manufacturing

As one of the must-use machines for heating pipe manufacturers, the FH-149A handles two critical welding operations in the production process: joining resistance wire with lead posts (lead bars) and connecting lead posts with terminal lugs. These connections form the electrical pathway within heating elements, and their quality directly impacts the durability and electrical performance of the finished heating tube.

Industrial and Civil Sectors

Heating tubes produced using this equipment serve both industrial and civilian applications — the industrial sector primarily includes cable heating applications, while the civilian sector encompasses daily electrical appliances and household heating products. Feihong machinery supports manufacturers supplying components across both market segments.
