Sky Fire Laser Professional Laser Welding Nitrogen Machine | ZHN-01

In welding, nitrogen's primary role is to remove oxygen, prevent re-oxidation, and improve weldability. Achieving high-quality welds requires both suitable solder and flux, with the latter cleaning oxides and enabling proper wetting. As a result, nitrogen is a key reactive gas in laser welding.

Special Note: This nitrogen generator can only power one welding machine; you will need to provide your own refrigerated dryer and air compressor.

Nitrogen Generator Product Advantages

1. Cost savings: A nitrogen generator can significantly reduce the cost of nitrogen compared to purchasing compressed gas cylinders.
2. High purity: Nitrogen generators produce high purity nitrogen for a wide range of applications.
3. Long service life: Nitrogen generators have a long service life and require minimal maintenance, making them a reliable and cost-effective nitrogen supply solution.
4. Convenient: With a nitrogen generator, you can generate nitrogen whenever you need it, without having to wait for delivery or refilling cylinders.
5. Improved safety: Nitrogen generators eliminate the need to handle high-pressure gas cylinders, which can reduce the risk of accidents.
6. Customizable: Nitrogen generators can be customized to meet the specific needs of different industries and applications.

Product parameter information

ZHN-01 Panel parameters and detailed diagram of back hole

Panel Parameters:

Flow meter: can control the outlet flow rate, lowering the flow rate appropriately can increase the concentration.

Programmable time relay: can adjust the working order and pressure relief time of AB tanks. Generally, the best time is set before leaving the factory, and users do not need to adjust it.

Air inlet: Use 8mm air pipe for the air inlet. The air source must be dehydrated and deoiled before being connected to the nitrogen generator.

Nitrogen outlet: The outlet hole uses a 6mm air pipe, and the outlet of qualified nitrogen can be used directly.

Back Hole:

Air pressure gauge: can check the pressure value before entering the nitrogen generator in real time. Under normal circumstances air pressure should be between 0.6-0.8MPA.

Nitrogen pressure gauge: real-time pressure value in nitrogen tank.

Pressure gauges for tower A and tower B: can check the pressure values in the A and B: carbon molecular sieve tanks in real time.Under normal circumstances, only one tank of tower A or tower Bis in working state, and the other is in pressure relief or low pressure state.
