High-Quality 420261 Plasma Cutting Nozzle from China Suppliers - Reliable Factory Component for Efficient Cutting Tasks
Model: 420261
Material: Made of high purity copper, the surface may be coated with special coating to improve wear resistance and high temperature resistance.
Structure: The internal design of the plasma cutting nozzle includes a small orifice to focus the plasma arc, ensuring cutting accuracy and stability.
- Applicable current range: usually 20-45A rated current.
- Applicable gas: air, nitrogen or other recommended gas.
- Aperture: According to cutting requirements design, the specific size can refer to the official information.
Main functions: The plasma cutting nozzle is combined with the electrode to focus and stabilize the plasma arc, while controlling the gas flow to ensure the concentration and stability of the high-temperature plasma during the cutting process.
Working principle: In the plasma cutting process, the gas is ionized into plasma through the small hole of the plasma cutting nozzle, forming a high-temperature, high-speed plasma arc, which is used to melt metal and achieve cutting.
- High precision cutting: The orifice design of the plasma cutting nozzle ensures a concentrated plasma arc for fine cutting.
- High temperature resistance: The copper plasma cutting nozzle can withstand the high temperature of the plasma arc, while extending the service life through gas cooling.
Frequency of replacement: The plasma cutting nozzle is a consumable and its service life depends on the frequency of use, the thickness of the cutting material and the operating conditions. Usually, it needs to be replaced when the cutting quality decreases or the plasma cutting nozzle hole becomes deformed.
Inspection method: Periodically check whether the plasma cutting nozzle hole is deformed, enlarged or blocked, and check whether the plasma cutting nozzle surface is ablated or damaged.
Installation precautions:
- Make sure the cutting machine power off before replacing the plasma cutting nozzle.
- Clean the plasma cutting nozzle seat to avoid dust or debris affecting the installation.
- Install correctly according to the operation manual to avoid damaging the plasma cutting nozzle or other components.
- Operating specifications: Set the correct current, gas pressure and cutting speed to extend plasma cutting nozzle life.
- Storage conditions: Store the plasma cutting nozzle in a dry, dust-free environment to avoid moisture or contamination.
- Electrode: The plasma cutting nozzle is used in combination with the electrode to produce a stable plasma arc.
- Protective caps: Protective caps are used to protect plasma cutting nozzles and electrodes and extend their service life.
Possible causes: The current setting is too high, the gas pressure is incorrect, and the cutting speed is too slow.
Solution: Check the cutting parameters to make sure they comply with the operating manual.
Possible causes: Worn plasma cutting nozzle, damaged electrode, or impure gas.
Solution: Replace plasma cutting nozzle and electrode, check gas quality.
Possible cause: The gas contains impurities or the cutting material produces too much slag.
Solution: Use pure gas and clean the cutting area regularly.
