YIL1-01 Nitrogen Generator for Laser Welding

In the welding field, the main function of nitrogen is to isolate oxygen during the welding process, increase weldability, and prevent re-oxidation. Reliable, high‑quality soldering requires not only suitable solder but  also the proper use of flux.The flux mainly removes oxides from the welding area prior to soldering and prevents re‑oxidation. It also creates ideal wetting conditions for the solder, thereby improving weldability. Nitrogen is one of the most prevalent and essential shielding gases for laser welding processes.

1. High-purity nitrogen (99.99%), customized ultra-high purity nitrogen 99.999%.

A nitrogen purity of 99.99% meets standard welding requirements. It fully blocks oxygen exposure during welding and effectively avoids common welding defects including weld yellowing, blackening, slag formation and pore generation.

For lithium battery welding and high-precision electronic component processing, we offer customized 99.999% ultra-high purity nitrogen. It delivers flawless, spotless welding surfaces and superior welding performance.

2. 15W Ultra-Low Engergy Consumption Design

Boasting ultra-low power consumption, this equipment consumes nearly negligible power under long-term continuous operation. With a total power draw of just 15W, its power demand is even lower than that of an energy-saving bulb.

When operating round-the-clock, the monthly power cost remains extremely low. Compared with traditional high-power nitrogen generators, the YIL1-01 achieves remarkable energy efficiency.

3. Plug & Play, Zero Assembly

Complicated pipe layout is unnecessary. Designed specifically for laser welding, the YIL1-01 nitrogen generator measures merely 450*500*770mm with a weight of 60kg, easily portable by two workers.

Simply set the unit on level ground, hook it up to a 220V power supply and a 0.6–0.8MPa compressed air source. It generates qualified nitrogen in just 20 minutes after startup, and operation requires no professional expertise.

4. Fast Payback, Dramatically Lower Gas Expenses

Buying liquid and bottled nitrogen repeatedly is standard for traditional welding processes. Apart from high raw gas prices, you also bear extra hidden costs for transport, manual handling and leftover gas waste.

The YIL1-01 works differently: just a single upfront investment for self-contained nitrogen production. With typical production volumes, you will recoup your investment in merely 1–2 years, with almost zero ongoing gas costs afterward.

5. Fully Automatic Operation, No Special Operators Required

Once powered on, the unit automatically performs gas production, pressure stabilization and purity regulation without any manual adjustments. It can run for more than 8,600 hours annually and boasts a 10-year service lifespan. Routine maintenance only involves regular compressed air quality inspections, with almost no extra upkeep required.

6. Compact & Portable, Suitable for All Working Scenarios

The YIL1-01 laser welding nitrogen generator occupies a floor space of less than 0.4 square meters, enabling flexible placement beside workbenches or in workshop corners. It can be effortlessly relocated to new positions whenever workshop layouts are adjusted.

Versatile in application, this unit perfectly fits hardware processing workshops, small sheet metal factories, laboratories, precision welding stations, and vocational school training environments.

7. Premium Export-Grade Quality, Ideal forGlobal Procurement

The YIL1-01 laser welding nitrogen generator utilizes mature PSA (Pressure Swing Adsorption) technology paired with imported carbon molecular sieves to deliver consistent, reliable performance. It runs on universal 220V AC voltage adaptable to worldwide power grids. CE certification and other relevant credentials can be supplied on clients’ demand.

FAQ

1. Q: How does a PSA nitrogen generator work?
A: The unit utilizes carbon molecular sieves, which adsorb oxygen far more rapidly than nitrogen molecules. It operates with two adsorption towers running in alternating cycles: one adsorbs oxygen under pressurization, while the other undergoes pressure relief for regeneration. Stable clean nitrogen can be obtained roughly 20 minutes after startup.

2. Q: What nitrogen purity levels are available?
A: Our standard nitrogen purity reaches 99.99%. For special scenarios such as electronic manufacturing and lithium battery welding, we offer customized ultra-high purity up to 99.999%.

3. Q: How long does it take to start producing qualified nitrogen?
A: About 20 minutes after power-on, the generator outputs 99.99% nitrogen. Then it runs automatically with stable purity and pressure.

4. Q: Are the daily operating costs high?

A: Not at all. The only ongoing expense is the power consumed by the air compressor. When compared to purchasing liquid nitrogen or bottled nitrogen, the nitrogen generator can deliver full cost recovery within 1 to 2 years under regular production output.

5. Q: Does the unit require a concrete foundation or complicated installation work?

A: Absolutely not. Simply place the machine on level ground, then connect it to a 0.6–0.8MPa compressed air source and a 220V power supply. It features plug-and-play operation and can be operated without professional expertise.

6. Q: What level of maintenance is required for this unit?

A: Maintenance workload is extremely minimal. The system operates fully automatically. You only need to inspect the compressed air quality periodically and replace filter elements when necessary. It boasts a 10-year service life and supports over 8,600 hours of annual running time.

7. Q: Which industries are applicable for this nitrogen generator?

A: It is widely adopted for laser and TIG welding, chemical purging processes, metal heat treatment, food packaging, electronics manufacturing (including PCB, LED and lithium battery production), tire vulcanization, coal mine fire suppression, as well as pharmaceutical packaging.
