5 m³/h Mini Nitrogen Generator for Welding

Our 5 m³/h Mini Welding Nitrogen Generator comes with a complete model range covering 1–20 m³/h, and fully supports custom configuration.

It blocks oxygen exposure during welding to eliminate weld yellowing, delivering consistently bright welding seams.

Equipped with fully automatic gas generation, it cuts both labor time and long-term operational costs.

Equipment Features:

1. Fast Start-up

Qualified nitrogen gas can be produced stably within 15 to 30 minutes after startup, realizing quick production and efficient operation.

2. Fully Automatic Operation

It supports 24-hour unattended automatic operation throughout the working process, effectively reducing manual intervention and labor costs.

3. High-Quality Molecular Sieve Filling

Adopts dense and compact molecular sieve filling technology. It features high adsorption efficiency, excellent durability and longer service life.

4. Flexible Parameter Adjustment

Nitrogen pressure, purity and flow rate are stable and steplessly adjustable, which can fully meet the diverse production requirements of different customers and working scenarios.

5. Energy-Saving & Stable Performance

With a reasonable structural design and advanced manufacturing process, the equipment runs safely and stably with low energy consumption and low operating loss.

Nitrogen Generator Working Principles

PSA (Pressure Swing Adsorption) Technology

PSA nitrogen generation adopts high-performance carbon molecular sieve to selectively adsorb oxygen from compressed air. By repeating pressure adsorption and depressurization desorption cycles, the system efficiently separates and outputs high-purity nitrogen steadily at room temperature.

This technology requires no high-temperature operation, featuring a simple process flow and compact equipment layout. It saves floor space, enables fast startup and instant gas output, and delivers low power consumption, low running costs, and high automation for continuous unmanned production.

Membrane Separation Technology

This 5 m³/h welding mini nitrogen generator applies hollow fiber membrane separation technology. It separates nitrogen and oxygen by leveraging their different permeation speeds through the membrane element, achieving fast nitrogen output with a simple equipment structure.

Membrane separation boasts easy operation and maintenance and rapid gas production. However, it demands high cleanliness of inlet compressed air. The hollow fiber membrane is subject to natural aging over service time and requires regular inspection and replacement to maintain stable gas quality.

Applications:

Our 5 m³/h Mini Welding Nitrogen Generator is widely applied in the packaging, sintering, annealing, reduction and storage processes of electronic components.

It serves multiple electronic manufacturing sectors, including wave soldering, reflow soldering, crystal processing, piezoelectric element production, electronic ceramics, copper strips for electronics, lithium batteries and electronic alloy material fabrication.

The electronics industry imposes strict standards on nitrogen quality, which usually demands nitrogen purity of 99.9%, 99.99%, or even ultra-high purity grades for premium production lines.

FAQ

Q: What standard flow rates are available?

A: Our standard in-stock flow specifications cover 1, 3, 5, 8, 10, 15 and 20 m³/h. Customized flow rate, working pressure and nitrogen purity are all supported to meet personalized requirements.

Q: Can one nitrogen generator serve multiple welding machines?

A: Yes. When configured with 1.2 times the peak simultaneous gas consumption, a single nitrogen generator can stably supply gas for multiple welding devices. This effectively reduces equipment investment and saves workshop floor space.

Q: How long does the unit take to reach standard nitrogen purity after startup?

A: The equipment reaches stable and qualified nitrogen purity within approximately 20 minutes after startup. Afterwards, it runs fully automatically with constant pressure and consistent gas purity.

Q: Does the equipment require professional on-site installation after delivery?

A: Professional on-site installation is not mandatory. We provide free remote installation guidance, or you can arrange local technicians for installation. The process only includes gas circuit and electric circuit connection plus simple parameter setting. Customers only need to prepare a matched air compressor and air storage tank in advance.

Q: Is the operation interface complicated?

A: The unit adopts intelligent PLC touchscreen control with dual Chinese and English language options. It supports one-key startup and fully automatic operation. For daily use, operators only need to simply monitor the purity meter and pressure gauge, with minimal manual operation required.

Q: What are the environmental requirements for equipment operation?

A: The working ambient temperature should range from 5°C to 40°C with good ventilation. The working area must be free of corrosive gases and keep a flat placement surface. No special foundation construction is required for installation.
