Stronger Welds. Straighter Beams. Superior Structures.
In the fast-paced world of pre-engineered buildings, speed matters—and so does precision.
Primo’s Pull-Through Welder and Gantry-Clamp Welder are engineered to handle high volumes, tight tolerances, and the nonstop demands of I-beam and structural steel production.
Laser-Guided Motion. Consistent Welds. Stronger Trailers.
When you’re building long, heavy-duty trailers, every weld needs to be tough, clean, and consistent.
Primo’s Pull-Through Welder and Gantry-Clamp Welder give you the automation, control, and repeatability to weld faster—with zero distortion and zero do-overs.


















In July 2023, we had the opportunity to tour two Primo Auto Welder machines in Georgia, where the clients expressed how pleased they were with their equipment. After seeing their success, we purchased a Primo Auto Welder for our own operations. From the time of purchase to installation, the process was seamless, and the machine was fully up and running within 30 days. The quality of the equipment, combined with the professionalism and support from Baloo and the Primo Auto Welder team, has made this an outstanding experience from start to finish. We would be honored to host anyone ready to see it in action.Nathan King President, Rainbow Building Systems Dallas, Texas
When we first started thinking about implementing automation, I was worried it might be too complex for my crew. But Primo’s Pull-Through Welder proved me wrong from day one. The touchscreen interface is so easy to use that my team was producing perfect beams in just a few hours, which immediately made us more productive. The twin-wire system delivers straight, distortion-free welds every time—no rework, no wasted hours. It’s not just efficient; it’s economically viable, giving us a fast return on investment. Also, their installation team stayed with us throughout the first runs to make sure we were assured before they left. That level of service is rare to find these days.

We switched to the Gantry-Clamp Welder after years of fighting with beam misalignment, and the difference is stark. The hydraulic clamping holds everything rock-solid, and the laser seam tracking nails the weld right at the root every single time. What I love most is that Primo built the layout around our shop, not the other way around. They really listened, and it shows in the results—we’re faster, more consistent, and our operators actually enjoy running it. President Company specializing in Steel Building Solutions Tennessee
As a trailer manufacturer, straight frames are non-negotiable. The technologically advanced, state-of-the-art Gantry-Clamp Welder—with its hydraulic system and twin-wire setup—delivers flawless, high-strength welds every time. What really impressed me was how quietly and smoothly it runs, making our shop more efficient and less chaotic. And with its modular design, we can scale up without starting from scratch. Primo’s team understands the industry inside out and built this machine to tackle real-world challenges head-on. President Top US Trailer Manufacturer Texas
We’ve been in structural steel fabrication for decades, and I’ve seen plenty of ‘high-tech’ promises that never deliver. Primo’s machines are the real deal—straight beams, tight tolerances, and zero rework, all backed by more automation features that streamline every step. The Pull-Through Welder’s laser-guided accuracy is unmatched, especially on challenging 6-inch webs where others fall short. It’s easy to operate, and the quality of weld appeal speaks for itself. Best of all, the ROI showed up in our numbers within just a few months.Vice President Metal Roofing Manufacturer Colorado
From the moment Primo’s crew arrived, the experience felt different. Their faster delivery with quick installation meant we were up and running in no time. They weren’t just installing equipment—they were making sure it was optimized for us. The Pull-Through Welders have transformed our production line: setup times are nearly zero, weld quality is unmatched, and output has surged. Their better after-sales service, with immediate response, combined with a reliable system of troubleshooting, keeps us operating without costly delays. Looking back, I only wish we’d made the switch sooner. President Pre-Engineered Metal Construction company Mississippi

Primo didn’t just sell us a machine—they delivered a game-changing solution. The Pull-Through Welder’s layout flexibility meant it dropped straight into our workflow without disrupting a thing. It runs all day without a hiccup, and switching beam sizes is as simple as clicking a dropdown—no manual tweaks, no downtime. We’ve slashed labor costs, eliminated camber issues, and unlocked the capacity to take on bigger contracts without bottlenecks. And Primo’s after-sales support? Every bit as outstanding as the machine itself—fast, responsive, and always there when we need them.
