Nitrogen Generator - 1 To 2

The EVER VIEW Nitrogen Generator - 1 To 2 is tailored for workshops equipped with two laser welding machines or dual welding stations. A single unit continuously supplies stable shielding nitrogen to two welding points, resolving the pain points associated with traditional bottled nitrogen, such as frequent cylinder changes, pressure fluctuations, high procurement costs, safety hazards related to cylinder storage, and production stoppages due to gas outages.

Laser Welding Gas Supply Principle

During high-temperature laser welding, nitrogen acts as an inert shielding gas to isolate the weld from atmospheric oxygen, preventing oxidation of the molten pool, weld seam discoloration, porosity, and spatter. Using compressed air as the raw material, the system employs carbon molecular sieves to separate and produce 99.999% high-purity nitrogen. It provides an uninterrupted 24-hour gas supply, supporting the welding of stainless steel, carbon steel, aluminum alloys, hardware kitchenware, automotive parts, custom sheet metal, and more.

Core Technologies

1. Air Purification

Compressed air undergoes multi-stage precision filtration to remove water, oil, and dust; clean air protects the molecular sieves and extends equipment lifespan.

2. Adsorption Separation

Clean air enters dual adsorption towers; carbon molecular sieves selectively adsorb oxygen, outputting high-purity nitrogen for use as welding shielding gas.

3. Alternating Regeneration

The dual towers operate in rotation—one produces gas while the other depressurizes to desorb and regenerate—ensuring stable, continuous gas supply around the clock and supporting simultaneous full-load production at two stations.

Key Product Advantages

1. Shared Supply for Two Stations (One-to-Two): Saves Investment and Floor Space

A single unit supplies two laser welding machines, eliminating the need for two separate small-scale nitrogen generators. This reduces initial procurement costs, saves workshop floor space, and simplifies piping installation and maintenance, making it a highly cost-effective choice for small and medium-sized metal fabrication plants with dual-station setups.

2. Significant reduction in long-term gas costs (60%–70%)

Bottled nitrogen entails hidden costs such as cylinder rental, transportation, labor for cylinder replacement, and downtime losses due to gas outages. On-site nitrogen generation consumes only compressed air and a small amount of electricity; the gas cost is just one-third that of bottled nitrogen, and the investment payback period for a dual-station workshop is only 2–3 months.

3. Safer workshop usage and simple operation

High-pressure cylinders require dedicated storage areas and frequent manual handling, posing risks of impact and leakage. The EVER VIEW "one-to-two" nitrogen generator produces gas on demand and operates at low pressure:

- One-touch start/stop; fully automatic, unattended operation after parameter setup

- Compact design allows for placement directly next to the welding production line

- Eliminates the need for frequent cylinder transport and stacking; includes an automatic drainage module to reduce daily maintenance

4. Intelligent industrial control system

All models come standard with PLC and touchscreen controls for real-time monitoring of nitrogen purity, flow rate, and pressure. Automatic alarms trigger upon parameter anomalies, ensuring consistent welding quality. The unit features a low-noise cabinet design, suitable for continuous two-shift workshop production.

Real-world factory application case study

Project Background

A medium-sized stainless steel kitchenware processing plant in Zhejiang operated two laser welding machines to manufacture stainless steel cookware and sinks, originally relying on bottled nitrogen.

Previous Challenges

1. The two workstations consumed 2–3 cylinders of nitrogen daily; workers spent 1.5 hours per shift changing cylinders, limiting production capacity.

2. Unstable gas pressure caused weld discoloration and oxidation defects, resulting in a 12% rework rate for post-weld polishing.

3. Monthly costs for nitrogen procurement and cylinder rental totaled $1,100, with a large number of cylinders occupying valuable storage space.

Retrofit Solution and Implementation Results

Selected the EVER VIEW N2-PR-T2 Nitrogen Generator - 1 To 2 to meet dual-workstation requirements:

1. Eliminated the daily cylinder-swapping process, increasing continuous production line efficiency by 18%;

2. Stable 99.999% high-purity nitrogen eliminated oxidation defects, reducing the polishing rework rate to 2.3%;

3. Monthly gas costs dropped to $360, with the equipment investment cost recovered within 3 months;

4. Eliminated the need to stockpile high-pressure cylinders on-site, resulting in a tidy workshop and significantly reduced fire safety risks.

FAQ

Q1: Will a pressure drop occur if two welding machines are operating at full load simultaneously with the EVER VIEW Nitrogen Generator - 1 To 2?

A: No. The equipment features a dual-tower cyclic gas generation structure for stable, continuous nitrogen output, and internal independent distribution piping balances the outlet pressure for both lines. Simply select the appropriate model based on the combined gas consumption of the two welding machines; purity and pressure remain stable even during simultaneous full-load welding. We offer free gas consumption analysis and model selection services.

Q2: How long does it take to recoup the purchase cost of the nitrogen generator compared to using bottled nitrogen?

A: For most workshops operating two stations daily, the payback period is 2–4 months, depending on daily welding duration, materials processed, and previous nitrogen consumption. After the initial purchase, the system consumes only compressed air and a small amount of electricity, eliminating ongoing costs for gas purchases or cylinder rentals.

Q3: Is the nitrogen generator difficult to maintain? Can regular operators handle it independently?

A: Daily operation is extremely simple: it features one-touch startup and runs automatically after initial setup. Routine maintenance requires only replacing the precision filter element every 6–12 months, and the built-in automatic drainage system minimizes the need for manual cleaning. Instructional videos and printed manuals are provided, allowing workshop staff with no prior experience in gas equipment to get up to speed quickly.
