We stand ready to supply gases in bulk, liquid Dewars, tube trailers, or high pressure cylinders. Our qualified laser experts can determine and recommend the best method to meet the specific flow and pressure parameters for your laser.
Impurities in resonator gases can damage optics and reduce laser beam quality. Proper high-purity equipment is essential to maintaining the purity of laser gases.
Nippon Sanso Matheson’s LaserPro regulators and switchover systems have the same high-quality components (stainless-steel diaphragms, high leak integrity, etc.) used for years in critical laboratory and research applications.
LaserPro switchover systems provide continuous supply of resonator gas eliminating the need to shut down for cylinder changeouts, enhancing productivity. Systems are available for CO2/N2/He premix or for individual pure gases (real time mixing). Rack or wall mount.
Assist gases often require high pressures and flow rates. The Nippon Sanso Matheson LPHF Assist Gas Regulators utilize dome-loaded technology to handle this heavy duty application. The advantage of dome-loaded regulators is the stable delivery pressure under varying flow conditions, as well as almost-instantaneous flow when the laser calls for assist gas.
A standard spring-loaded diaphragm regulator experiences some lag time before flows and pressures stabilize. Dome-loaded technology allows for faster piercing times which are especially important if the customer nests many parts on one sheet. The dome-loaded regulators are also very durable, outlasting their spring-loaded counterparts.
Industrial laser systems may require resonator gases and assist gases, depending on the laser technology and material being processed. Nippon Sanso Matheson supplies high-purity LaserPro™ gases and related gas-control equipment for resonator gases. Resonator gases are typically used within the laser resonator for beam generation in CO2 lasers, although He:Ne also use gas, but are less common in production. Most new laser technology is called ‘fiber’ lasers. These are a type of solid-state laser where the beam is generated in a fiber doped with Yb atoms, where the active medium is Yb (ytterbium) distributed in a fused silica fiber optic cable. Fiber lasers do not require high purity resonator gases to generate the beam, but they do use nitrogen, oxygen, or a mixture of nitrogen and oxygen to push the molten metal out of the cut.
Nippon Sanso Matheson supplies high-purity resonator gases and assist gases for industrial laser systems. Nippon Sanso Matheson understand the high flow and relatively high pressures use in assist gas supply. Nippon Sanso Matheson builds custom engineered bulk systems, including pressure building systems designed to meet these needs. Nippon Sanso Matheson also provides regulators, switchover systems, gas-control equipment, customized delivery solutions, and complete turnkey gas supply systems.
Impurities in resonator gases can damage optics and reduce laser beam quality. High-purity gases and gas-handling equipment with high leak integrity help preserve gas quality as it moves from the source to the laser.
Resonator gases support operation of applicable laser sources, while assist gases are delivered at the cutting area to support the cutting process. Nippon Sanso Matheson supplies both categories, along with process gases and equipment engineered for their different purity, pressure, and flow requirements.
Laser resonator gases require high-purity equipment designed to avoid introducing leaks or contaminants. Nippon Sanso Matheson’s LaserPro regulators and switchover systems use components such as stainless-steel diaphragms and are designed for high leak integrity.
An automatic switchover system can maintain a continuous resonator gas supply while cylinders are changed. Nippon Sanso Matheson offers LaserPro switchover systems for premixed carbon dioxide, nitrogen, and helium or for individual pure gases used in real-time mixing.
High-flow laser assist applications may benefit from dome-loaded regulator technology, which provides stable delivery pressure under varying flow conditions. Nippon Sanso Matheson’s LPHF assist gas regulators are designed for the high pressures and flow rates associated with these applications.
Yes. Nippon Sanso Matheson provides customized laser gas solutions based on operating requirements, including flow, pressure, gas purity, supply mode, and equipment configuration. The company can also provide a complete turnkey gas supply system for the laser application.
Nippon Sanso Matheson can supply gases for laser applications in bulk, microbulk, pallet mounted tanks with integrated pressure building systems, 6-packs of cylinders, 12-packs of cylinders, 18-packs of cylinders, liquid Dewars, bulk tanks tube trailers, or high-pressure cylinders. Its laser specialists evaluate required usage, flow and pressure parameters to recommend an appropriate supply method.
Nippon Sanso Matheson combines high-purity LaserPro gases, laser-specific gas-control equipment, multiple supply modes, custom engineering, and laser application expertise. This enables manufacturers to source both the gases and the associated delivery system from one industrial gas supplier.
Automation in metal fabrication can improve worker satisfaction and safety while also improving productivity and cost per weld. In an industry with pressure on the availability of qualified workers, automation enables the human staff to upgrade to higher-value functions.
On the metal fab shop floor, automation is well-suited to:
With many choices available, and many decisions to make, your Nippon Sanso Matheson representative and automation specialist can offer valuable assistance to save you time and work with you while you navigate the options. Contact us.
Numerous engineering choices put automation within reach for large and small operations.
Pre-engineered Cells are typically used for a part family or a group of similar sized parts. Pre-engineered cells typically include integrated safety features and often include integrated positioners. They are usually set up with two stations, so one part may be welded while another part is being loaded.
Fully Customizable Cells are typically intended for a single repeated operation (as opposed to a sequence of operations). Customizable Cells are designed to be “trained” easily by the end-user using a computer or tablet.
Collaborative Robot (Cobot) is a type of customizable cell that is small and transportable – designed to be moved around the shop and easily set up for a new operation without requiring much unproductive time spent in set up and shake-down.
Plasma Cutting is an ideal application for automation, since patterns and straight cuts can be repeated easily.
Laser cutting tables – Nippon Sanso Matheson can also help provide you with a laser cutting table. We know your process, and you can count on us for long term support.
Positioners – Positioning your weldment during welding can eliminate safety risks involved with using cranes or forklifts to position parts. It can also reduce time wasted in your process. Contact us now to discuss positioning options.
Systems for other types of automation – such as dust removal, fume extraction, and parts vending – are also offered by Nippon Sanso Matheson. Read about them on this website, or contact your Nippon Sanso Matheson rep or store location.

Yes. A low carbon index (or low carbon intensity) gas is a gas whose production, transportation, and use result in lower lifecycle greenhouse gas emissions than conventional alternatives. The term is typically tied to a Carbon Intensity (CI) score, which measures the amount of CO₂-equivalent emissions generated per unit of energy or product across its entire lifecycle.
For industrial gases, the concept can include:
– Low-carbon hydrogen produced with carbon capture, renewable electricity, or low-emission feedstocks.
– Renewable natural gas (RNG) derived from organic waste streams.
– Carbon-captured or recycled CO₂ used in industrial applications.
