The Role of Gas in Welding: How nexAir’s Solutions Improve Performance and Safety
Shielding gas plays a crucial role in welding, affecting everything from arc stability to weld quality and operator safety. Whether you’re working with MIG, TIG, or Flux-Cored welding, choosing the right gas mixture can improve penetration, reduce defects, and create stronger, cleaner welds. With nexAir’s extensive selection of welding gases and expert guidance, welders can optimize their process for better results while maintaining a safe work environment.
Why Gas Matters in Welding
In most welding processes, shielding gas protects the molten weld pool from contamination by atmospheric gases like oxygen, nitrogen, and water vapor. Without proper shielding, welds can suffer from porosity, oxidation, and weak bonds, leading to costly rework or failures in structural integrity. The right gas selection prevents these issues and, enhances weld quality, reduces spatter, and improves overall efficiency.
Beyond shielding, gases are also used for cutting and purging applications. Plasma cutting systems, for example, rely on compressed air or gas mixtures to create precise, clean cuts, while purging gases help maintain weld integrity in stainless steel and other reactive metals. Understanding the role of gas in your specific welding application is key to achieving the best results.
Choosing the Right Gas for Your Process
Different welding processes require different gases, and selecting the right one can significantly impact performance. nexAir provides a range of high-purity gases and custom-blended mixtures designed to meet the needs of professional welders. Here’s a look at common welding processes and their ideal gas pairings:
- MIG Welding (GMAW): Uses argon, carbon dioxide, or a mix of both. Pure CO₂ provides deep penetration but creates more spatter, while an argon-CO₂ blend improves arc stability and weld appearance.
- TIG Welding (GTAW): Requires pure argon or argon-helium mixtures for clean, precise welds, especially when working with aluminum and stainless steel.
- Flux-Cored Welding (FCAW): Some self-shielding wires don’t require external gas, but gas-shielded flux-cored welding often uses a CO₂ or CO₂-argon mix to enhance performance and minimize spatter.
- Plasma Cutting: Compressed air works for general applications, but for cleaner, high-precision cuts, nitrogen or oxygen may be used, depending on the material.
By selecting the appropriate gas blend, welders can improve weld penetration, minimize defects, and create stronger bonds while maintaining cost efficiency.

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.
