Choosing the Right Welding Gas for Different Types of Welding Projects
Choosing the Right Welding Gas for Different Types of Welding Projects
Welding is a complicated process. Whether you’re a hobbyist looking to make a barbeque grill, or a professional creating parts for a luxury automobile, several factors must be taken into account.
One of the first factors to consider is the type of welding process. For instance, Metal Inert Gas (MIG) welding, which most beginners use, serves a different purpose than Electron Beam welding, which is more sophisticated and requires additional expertise.
Another big difference is the type of gas employed. Most welding projects require a steady supply of high-quality gas, ranging from acetylene to oxygen to specific blends like argon and carbon dioxide.
So, how do you choose the right welding gas for your project?
Begin by understanding the different welding processes.
Common Types of Welding and the Gases They Use
MIG Welding
A simple, quick, and beginner-friendly process is gas metal arc welding or MIG welding. It uses electric arcs to generate heat and join two pieces together. MIG welding is highly-accurate and is best used to fuse thinner materials together.
The most common gas used in this type of welding is argon, which is used for shielding, or protecting the weld puddle from contamination. Other gases can also be used for this process, including helium and carbon dioxide.
Oxyacetylene Welding
Oxyacetylene welding is another popular welding technique. It’s recommended for fusing together high-strength steels because of the intensity of the heat it generates. As the name suggests, this type of welding relies on a blend of oxygen and acetylene. The ratio of these two gases produces different results — a higher amount of oxygen makes the flame hotter, while acetylene provides the fuel.
While acetylene isn’t the cheapest gas to use for a DIY project, the ease of the process makes oxyacetylene welding a good choice for a beginner.
TIG Welding
Gas Tungsten Arc Welding, or TIG welding, is a more challenging process. It uses a tungsten electrode to send a current into the weld pool. It’s generally used to fuse together sections of stainless steel. This process also requires a steady supply of inert gas for shielding and is generally best performed indoors to avoid contamination.
The inert gases most commonly used in TIG welding include argon, which is the most cost-effective, and helium, which is rarer and more expensive. A blend of these two gases can also be used for thicker metals.
At the end of the day, the gas you select depends on your needs. Some, like carbon dioxide, are more cost-effective but produce lower-quality welds. Others, like helium, provide a deeper cut, but are harder to procure.
Several processes also involve specific blends of oxygen, hydrogen, nitrogen, and argon to either minimize spatter, speed up the process, or provide greater arc stability.

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.
