Primo Automation
Tailored to Fit Your Shop. Engineered to Exceed Your Goals.
The Primo Pull-Through Welder isn’t just automated—it’s engineered for your beam sizes, your floor space, and your output goals. Whether you’re building structural steel, trailer chassis, or heavy-duty beams, it works the way you do—only faster, smarter, and more precise.
WHAT
Makes it stand out…
Weld Smarter. Finish Faster. On Your Terms
Simultaneous Twin-Wire Welding
You weld both flanges at once—with perfectly balanced heat input. That means no distortion, no camber, and no corrections. Just clean, straight beams, every time.
Laser-Guided Root Tracking
You get pinpoint accuracy—four high-speed laser sensors track your joint and guide the weld to the exact root. No guesswork, no adjustments, just repeatable perfection.
Precision That Delivers—Even at 6”
Even when you’re working with 6-inch webs, your torches stay perfectly centered and opposite. You don’t sacrifice quality, no matter the beam size.
Consistent Beads. Cleaner Welds.
You can expect perfect fillet formation within ±0.2 mm—helping you meet quality standards faster, with minimal post-weld rework.
Automation That Works for You
Automatic Setup. Zero Guesswork.
You just select what you need—fillet size, flange height, web thickness—and the machine does the rest. Voltage, speed, and wire feed adjust automatically to match.
Smart Torch Memory
Your system remembers exactly where it left off—even after a shutdown. So when you’re ready to restart, it’s ready to go. No recalibration needed.
Adapts Instantly to Beam Changes
Changing beam sizes? Just select from the dropdown menu and your rollers reposition automatically—no manual tweaks, no wasted time.
WPS-Backed Weld Settings
You stay compliant without extra effort. Weld parameters are locked to your WPS specs and applied consistently—regardless of who’s running the machine.
Smarter PLC for Smoother Control
Need to adjust the root mid-weld? Pause the cycle? Override a sensor? You can—because the system is designed to think with you, not against you.
Weld Quality That Speaks for Itself
Cooler Welding = Straighter Beams
Your beams stay true, thanks to integrated copper rollers that pull away excess heat. Less warping. More precision. Better results.
Grounding That Protects Your Work
You get a cleaner arc and fewer flange marks—with copper grounding rollers and optimized cabling that improve performance and extend life.
Infeed Alignment You Can Rely On
A hydraulic pusher keeps your flanges steady and aligned on the infeed conveyor—essential for long beams where even slight drift matters.
Magnetic Holding for Easy Handling
Electromagnets hold flanges vertically in place while you tack or flip—so you don’t need extra hands, tools, or time to get the job done.
Efficiency That Moves with You
Wire Drums That Keep You Welding
Your welding doesn’t stop when the wire runs low. With space for four 1000 lb drums, you can go longer between changeovers and keep your uptime high.
Flux Handling That Takes Care of Itself
You don’t have to manage the flux manually—it’s preheated, delivered, and recovered automatically. Cleaner welds. Less waste. Fewer steps.
Hydraulics That Work Quietly in the Background
Your system runs smoother with automatic pressure control, oil cooling, and easy-to-read maintenance indicators. No noise, no hassle—just reliability.
Built Around Your Shop. Designed for Your Team.
Layouts That Match Your Workflow
Your space. Your material flow. Your output targets. Every line is engineered to fit the way you work—with optional flippers, splice welders, conveyors, and more.
Operator-First at Every Touchpoint
From intuitive touchscreens to one-button operation, wide platforms to full-length safety guards—it’s all designed to make life easier for your team.
Durability You Can Count On
You get more out of every component—zirconium-copper tips, insulated flux tubes, hardened rollers—built to handle high volumes and heavy use.
Proven Where It Matters
With 650+ installations across India, the Middle East, Asia, and North America, with Primo, you’re joining a trusted global network that’s already welding better.
Add-Ons That Take Your Line Further
Your welding line should work the way you do—and grow with your production needs. That’s why Primo offers modules like the Tack Welder and Splice Welder—designed to streamline assembly, extend beam lengths, and drive efficiency from start to finish. Add them to your system when you’re ready—and scale up without slowing down.
