Plasma cutting dual-flow nozzle
The plasma cutting double-flow nozzle has separate channels for plasma gas and secondary gas. This improves arc constriction and focusing, and increases wear part life.
Physical-Chemical Mechanism of Action
The plasma cutting dual-flow nozzle carries two separate gas streams: a primary gas (plasma gas) and a secondary gas. The plasma gas forms the arc, while the secondary gas supports arc relief and focusing.
Metallurgical Relevance & Welding Risks
Correct setup of the dual-flow nozzle ensures precise and efficient plasma formation, leading to better material processing. However, incorrect settings can worsen the arc or reduce its lifespan.
Workshop Practice & Procedures
Make sure the plasma gas and secondary gas are fed into the correct channels. Adjust the gas flows so the arc is clear and focused. Regularly check and clean the nozzle to maximize its life.
