A working knowledge of the ways in which purity, pressure, and flow affect how lasers use gases is key to setting up a gas delivery system that both works correctly and is cost-effective.

Keeping these tips in mind during safety and performance audits can help you keep the shop floor safe even when potentially dangerous fabricating activities are taking place.

Continuous supply of gas to a fabricating activity is the goal of any shop. Fabricators may not realize that they have choices in gas delivery system design that help to ensure uptime is maximized.

cación en metal puede ser complicado, especialmente si el gas necesita llegar a varios lugares. Si usted está buscando ahorro en costos y ganancias en la productividad, considere instalar cilindros de gas en una ubicación principal y controlarlos con un múltiple básico o con un múltiple conmutador.

Supplying gas to your metalworking applications can be complicated, especially if the gas needs to reach multiple locations. If you are looking for cost savings and productivity gains, consider installing gas cylinders at one main location and controlling them with a basic manifold or switchover manifold. With this method you won’t need to worry about cylinders running out of gas.

Precise assist gas delivery is essential in CO₂ laser cutting. The resonator is a key component, especially if gas delivery will be uninterrupted for unattended machine operation. Assist gas volume and pressure also must be appropriate for the application to ensure the best results.

The NFPA-51 standard outlines how to properly store, transfer, and use industrial gases; how to handle such gases while they are in their gaseous or liquid phases; and how to implement storage, piping and distribution, and operating practices. While most safe practices are based on common sense, others may take volumes of technical reference, as specified in NFPA-51, to explain.
