Automatic Changeover Valves for Laser Cutting Machines
July 1st, 2022
Nitrogen gas laser cutters use heat from a laser to melt metal material, creating precise and uniform cuts. Nitrogen gas is then used to remove any leftover metal from the cut and surface. When the gas cylinders have been depleted, operations cease until new, full cylinders have been installed into your machinery. The delay created by manually changing cylinders can result in costly interruptions, imprecise cuts, and other critical failures.
Assurance Valve is here to help. We are a top source of knowledge, resources, of high-performing automatic gas cylinder changeover valves for any industry, including laser cutting applications. We can help you better understand automatic switching for your gas laser cutting equipment and enhance your cutting processes today.
Nitrogen Gas for Laser Cutting
While oxygen is the most common gas choice for laser cutting due to its extreme availability, nitrogen gas creates cleaner cuts at a faster rate. This is because nitrogen is an inert gas and does not generate the same heat-producing reactions as other gases. Nitrogen works to eliminate any impurities that could impact your laser cutting application while lowering the chance of oxidation occurring within the cut. Oxygen is displaced from the surface, producing a high-quality finish, and significantly reducing the necessary preparation time before welding occurs.
How Manual Changeover Valves Negatively Impact Laser Cutting
Laser cutters use nitrogen gas at a rate of 40 to 60/120 m3/hour. This rate of use means that is essential to keep all replacement cylinders easily accessible. Traditional nitrogen cylinder changeover systems require employees to swap depleted canisters manually or use a switchover valve that relies on electricity. When cylinders are emptied, operations come to a standstill. Other disadvantages of classic changeover systems include:
- Higher rate of disrupted laser cutting processes
- Higher risk of worker injury or exposure to dangerous gases
- Higher labor costs
- Lower output due to mid-cut interruptions
- Wasted product left in the “spent” nitrogen gas cylinder
Choose an Automatic Gas Cylinder Switchover Valve
Non-electric, easy to operate, and easy to install, the Eliminator automatic gas cylinder changeover valve is an ideal solution for nitrogen gas laser cutting applications run by individuals or small-scale facilities utilizing smaller tanks. Our automatic switchover valve is endlessly customizable to accommodate 2, 4, 6, or 8 cylinder laser cutting setups with custom options available. Automatic changeover valves come with numerous benefits over other nitrogen gas switchover valves, including:
- Minimizing the risk of interrupted laser cutting processes
- Lowering labor costs due to automatic gas cylinder switchover capacities
- Significantly lowering the risk of gas exposure to employees
- Significantly lowering loss of product
- Increasing efficiency compared to manual or electric changeover systems
