My name is Nathan Milleson, and for over 15 years, I’ve had the privilege of helping metal fabricators improve production efficiencies, eliminate bottlenecks, and cut operational costs. In my work as a Sales Engineer at Mac-Tech, I focus on advanced solutions that directly address the challenges my customers face on their shop floors every day. One of the most game-changing technologies I’ve seen—across shops of all sizes—is on-site nitrogen generation. It’s not just about convenience; it’s about thousands saved annually and a real-and-measurable ROI that can be achieved in as little as one year for three-shift operations.
My 15+ Years Helping Fabricators Cut Costs and Boost Efficiency
Over my career, I’ve seen first-hand how shops that rely on external gas deliveries deal with unpredictable pricing, supply-chain hiccups, and the hassle of juggling tank inventory. My approach is simple: if there’s a way to minimize your overhead while boosting productivity, I’m all in. That’s what brought me to on-site nitrogen generation, a technology that replaces the worry of cylinder deliveries with the convenience of having a constant supply of nitrogen. By installing the right system tailored to a customer’s workflow, I’ve been able to help fabricators eliminate delivery fees, cut per-part gas expenses, and streamline overall operations.
I’m a firm believer in the value of practical, real-world knowledge. I don’t just talk about systems; I work with clients on actual production lines, run side-by-side comparisons, and personally verify how an on-site nitrogen system can improve the bottom line. Whether you’re a smaller shop running a single shift or a facility that’s busy 24/7, I’ve seen the numbers: one-shift shops often hit ROI in three years, increasing to two-shift shops that achieve ROI in two years, and three-shift shops that see their investment pay for itself in about a year. And these are not just claims—these are results I’ve personally been part of delivering.
Real-World On-Site Nitrogen: Faster ROI and Hands-On Success Stories
One of my favorite examples is a client who jumped from spending thousands each month on nitrogen deliveries to saving nearly 30% on gas expenses—immediately—by installing a mid-range on-site generation unit. For them, it wasn’t just a cost decision; it also freed up precious shop floor space because they no longer stored cratefuls of cylinders. After the installation, we analyzed their productivity metrics and found their laser cutting efficiency improved by nearly 20%, reducing bottlenecks and overtime costs.
Another success story involves a larger shop running two shifts that consistently consumed high volumes of nitrogen for both laser cutting and welding. Their ROI timeline was right around two years, and they were thrilled to reinvest the money they saved into new automation equipment. The real difference, they told me, was the peace of mind—knowing they never had to worry about a late gas delivery or abrupt price hikes ever again. Today, they produce more parts per hour, experience minimal downtime, and enjoy the flexibility of controlling their own supply.

Frequently Asked Questions
Q: How do I know if my shop’s production volume justifies on-site nitrogen generation?
Often, the best place to start is by reviewing your monthly gas usage and costs. I’ll help assess your current and future demands to determine the ideal system size for your needs.
Q: What kind of maintenance does an on-site nitrogen generator require?
Maintenance is generally straightforward—regular filter changes, system checks, and ensuring the compressor runs smoothly. Our Mac-Tech service team and I provide clear maintenance schedules and training to keep things simple.
Q: Will an on-site nitrogen generator work with my existing cutting or welding equipment?
Absolutely. We select systems that integrate seamlessly with your current setup. I’ll collaborate with your production team to make sure everything is compatible and optimized.
Q: How quickly can I see ROI if I’m only running one shift?
Based on real-world results, single-shift operations typically see ROI in about three years. However, this can vary depending on your specific production demands.
Q: Does Mac-Tech offer support if I have any downtime or technical questions?
Yes. From remote troubleshooting to on-site visits, I’m always here to make sure you stay productive. Our nationwide service network means help is never far away.
Closing Thoughts
I’ve spent my career focused on one main goal: helping fabricators thrive by finding smarter ways to work. On-site nitrogen generation is one of those proven, practical solutions that can pay for itself—sometimes in under a year. If you’re ready to explore what this technology could mean for your shop, don’t hesitate to reach out. I look forward to working with you and mapping out a tailored plan for sustainable, long-term success.
