Oxygen as a Plasma Cutting Gas
Oxygen as a Plasma Cutting Gas
Oxygen is not only vital for human survival but also has several industrial applications. Apart from its obvious medical uses, it is a crucial gas for industries like metal fabrication, construction, and automotive repair.
Oxygen is commonly used in plasma cutters as it offers the fastest cutting speed and the highest quality of cuts compared to other plasma gases.
What is plasma cutting?
Plasma cutting is the process of cutting through electrically conductive surfaces such as aluminum, brass, copper, and steel using a jet of hot plasma.
A plasma cutter sends pressurized gas through a small channel to create a circuit. A spark is then generated between a negative electrode and metal which reacts with an inert gas to create a stream of plasma that reduces the metal to molten slag.
The most common plasma gases that are sent through a cutter include nitrogen, argon, and oxygen.
Advantages of Oxygen as a Plasma-Cutting Gas
Why do some consider oxygen to be the best gas for plasma cutting?
With the right KnowHow, oxygen can offer the cleanest cuts and faster cutting speeds. This is especially true when it is used on carbon steels with thicknesses of up to one and a quarter inches.
Oxygen offers the highest-quality mechanized cuts with a smooth surface. In its plasma form, it interacts with carbon steel, creating fine molten metal which is conveniently ejected from the cut or kerf.
Oxygen is widely used in plasma torches for the same reason that it works well in acetylene torches. It reacts with steel to boost cutting speed and improve edge quality.
Apart from these benefits, oxygen is also known to work effectively in combination with other secondary fuels.
Disadvantages of Oxygen as a Plasma-Cutting Gas
On the other hand, the use of oxygen in plasma cutting also has its fair share of setbacks.
The high cost of oxygen doesn’t always make it the most convenient option, especially since other gases, like argon and hydrogen, could work just as well on certain metals.
Oxygen also doesn’t work as well on shiny surfaces, making it an ineffective gas when used to cut stainless steel and aluminum projects.
But when dealing with steel, oxygen has become the standard gas for businesses that want to Forge Forward as it offers the fastest cutting speed of any plasma gas.

Manufacturing downtime costs American companies billions annually. When production lines halt due to gas supply issues, every minute translates to lost revenue, missed deadlines, and frustrated customers. At nexAir, we've spent decades developing solutions that keep manufacturing operations running smoothly.
The Hidden Costs of Gas-Related Downtime
When manufacturers calculate downtime costs, they typically focus on labor and lost production. However, gas supply disruptions create cascading effects that multiply these losses:
- Production rescheduling that disrupts carefully optimized sequences
- Rush shipping fees to meet customer deadlines despite delays
- Quality inconsistencies when processes restart after interruptions
- Overtime costs to catch up after unplanned stoppages
- Reputation damage when delivery commitments are missed
For a typical mid-sized manufacturer, each hour of downtime represents $5,000-$10,000 in direct and indirect costs. Our analysis shows that gas-related issues cause 7-12% of total manufacturing downtime - a substantial opportunity for improvement.
From Reactive to Proactive: The Supply Continuum
Most facilities follow a predictable pattern in their gas management evolution:
Stage 1: Reactive Management At this stage, facilities order gas when they notice supplies running low or, worse, after running out. Emergencies are common, and disruptions are accepted as "part of doing business." One automotive parts supplier operating this way experienced 14 production interruptions in a single quarter.
Stage 2: Calendar-Based Management Facilities advance to scheduled deliveries based on estimated usage. While better than the reactive approach, this method still results in either excess inventory (tying up capital and space) or shortages when usage spikes occur. A plastics manufacturer following this model maintained 40% more cylinder inventory than necessary while still experiencing occasional stockouts.
Stage 3: Consumption-Based Management Our telemetry systems monitor actual gas consumption, automatically triggering orders based on usage patterns rather than calendar dates. This approach virtually eliminates both stockouts and excess inventory.
Stage 4: Integrated Supply Management The most advanced approach connects gas management directly to production planning systems. Upcoming production requirements automatically adjust supply parameters, ensuring resources are precisely aligned with needs. A medical device manufacturer using this approach reports zero gas-related downtime for 27 consecutive months while operating with minimal inventory buffers.
Our expert KnowHow™ in industrial gas applications allows us to guide customers through this evolution at a pace that makes sense for their operations.
Customizing Solutions for Maximum Uptime
Manufacturing environments vary dramatically in their gas requirements and operational constraints. We've developed flexible approaches that address these differences:
- For high-volume, consistent usage operations, our bulk systems eliminate the cylinder handling that frequently causes supply disruptions. Bulk installations include telemetry monitoring and automated ordering to prevent outages.
- For variable-demand environments, our microbulk delivery systems provide the benefits of bulk supply with lower volume commitments. These systems reduce handling requirements while maintaining the flexibility needed for changing production schedules.
- For specialized applications requiring multiple gas types, our gas management programs combine cylinder tracking, usage monitoring, and automated replenishment. This comprehensive approach ensures that specialty gases are always available when needed, regardless of how infrequently they might be used.
- For multi-site operations, our enterprise supply programs coordinate deliveries and optimize inventory across locations. By treating the organization's gas requirements holistically, we minimize both stockouts and excess inventory across the network.
This consultative approach ensures that manufacturers receive solutions aligned with their specific operational patterns rather than generic "one-size-fits-all" systems.
Beyond Traditional Supply: Integrated Services for Total Reliability
Maximum uptime requires more than just reliable gas delivery. Our integrated services address the full spectrum of gas-related reliability factors:
Equipment maintenance programs that prevent system failures before they impact production Technical gas specialists who resolve application issues that could otherwise cause production problems Safety training that prevents accidents leading to downtime events Emergency response capabilities that minimize impacts when unexpected events occur Supply chain redundancy that ensures continuity despite regional disruptions
These services complement our supply solutions to form a comprehensive reliability strategy. By addressing both everyday operations and exceptional circumstances, we help manufacturers Forge Forward with confidence that gas-related disruptions won't derail their production targets.
Measuring Success: The Results That Matter
The ultimate measure of any downtime reduction strategy is its impact on production metrics. Our manufacturing customers consistently report significant improvements after implementing our comprehensive gas management solutions:
Downtime reductions of 85-95% for gas-related issues Inventory cost decreases of 20-30% through optimized supply management Administrative time savings of 5-10 hours weekly through automated ordering and tracking Production schedule adherence improvements of 3-7% due to improved supply reliability
These performance gains translate directly to bottom-line benefits that typically deliver ROI within months rather than years. More importantly, they allow manufacturers to confidently make delivery commitments, knowing that gas supply issues won't compromise their ability to perform.
