When it comes to pulse welding, success depends on control. Not just the type of metal, current, or shielding gas, but how quickly your machine responds to what’s happening at the arc. The faster the system reacts, the better the weld.
At OTC DAIHEN, we engineered a custom microchip that reacts faster than anything else in the industry. It’s the foundation of our Welbee II series and delivers a 20-nanosecond response time. That means 50 million arc adjustments every second. For perspective, that’s four times faster than the nearest competitor.
This level of control leads to better welds, more consistent results, and less cleanup. And that means more productivity without sacrificing quality.
What Makes 20 Nanoseconds So Special?
Pulse welding works by switching between peak and background current, allowing precise heat control and cleaner droplet transfer. But unless your machine can keep up with real-time changes at the arc, you’ll see spatter, undercut, or even burn-through.
The nanosecond microchip inside the Welbee II series constantly monitors the arc and adjusts in real time. This improves:
- Arc stability and control across steel, stainless steel, and aluminum
- Droplet transfer and waveform regulation
- Bead consistency, even under fast travel speeds
It’s like having an experienced welder watching the arc and making micro-adjustments instantly, all shift long.
Better Welding Across Materials
Different metals have different welding behaviors. Welbee II adapts to all of them.
For mild steel
Our AI Enhanced Pulse automatically adjusts the waveform to reduce undercut and minimize spatter. And for applications where consistent weld depth is critical, Constant Penetration Mode keeps the arc behavior stable—even when there are slight changes in torch angle, joint gap, or material thickness. The result is repeatable, high-quality welds from part to part and shift to shift.
For stainless steel
Even with thicker wire or higher viscosity molten metal, the system controls droplet transfer cleanly. This gives you great-looking welds without needing a highly skilled hand.
For aluminum
The microchip stabilizes the arc and reduces spatter in a material that’s known for being tricky. It keeps the weld bead consistent, even in mid- to high-current settings where things tend to go off track.
Less Spatter, More Throughput
One of the most visible improvements is spatter control. With the CBT-EX mode enabled, Welbee II reduces spatter by up to 80 percent—even in CO₂ and MAG welding.
Less spatter means less time grinding and cleaning. Welders can move on to the next part faster, and your throughput improves without adding more labor.
Real Benefits in Real-World Production
This isn’t just high-spec marketing talk. The chip makes a difference where it matters—on the shop floor.
With Welbee II and its nanosecond processing, you get:
- Consistent penetration and fewer defects
- Automatic welding condition presets based on material and thickness
- Stronger welds with less warping or burn-through
- Lower gas usage, especially in aluminum where helium is typically required
You’ll also notice fewer interruptions. With better waveform control, tips last longer, components stay cleaner, and operators spend less time on adjustments.
Built for Today’s Fabrication Environment
Welbee II doesn’t just weld better. It integrates easily into modern operations. The system offers:
- Smart data logging for weld results, wire usage, and arc time
- Seamless integration with factory networks via EtherNet/IP, PROFINET, and more
- A user-friendly interface and remote control options that save setup time
Whether you’re using manual MIG stations or fully automated robotic lines, the result is the same—more control, fewer variables, better output.
Final Thoughts
At the core of OTC DAIHEN’s pulse welding system is a microchip that thinks faster than the arc can change. With it, your welds get smarter, your shop gets more efficient, and your team spends more time producing and less time fixing.
Welding isn’t just about heat and wire anymore. It’s about data, timing, and precision. And with 20 nanoseconds of control in every cycle, that precision is now built into every weld.
