Product description

Highlights at a glance

  • Specially designed for handheld laser welding machines
  • Designed specifically for industrial applications, with an extremely long service life. Not only do we offer the products, but we also provide a corresponding voltage fluctuation solution to eliminate your concerns during the production process.
  • In response to the unstable power supply situation in industrial sites, the TND-20 has an extremely wide input voltage adjustment range. Whether you are at a remote construction site or an old industrial park, as long as the voltage is within the working range, it can output high-purity stabilized electricity to ensure that the equipment operates at full capacity.
  • Designed specifically for handheld laser welding machines, it integrates overvoltage, undervoltage, overload, short circuit and overheating protection. In case of extreme abnormalities in the power grid, the TND-20 will instantly cut off the output or automatically adjust, acting like a "bodyguard" to protect the expensive laser generator and avoiding high maintenance costs.
  • It is equipped with a high-standard filtering system, which can effectively filter out the high-frequency harmonics and noise interference in the power grid. This ensures the smooth operation of the control system of the laser welding power supply and prevents shutdowns or sudden changes in welding parameters due to interference.
  • Industrial-grade structural design, with excellent heat dissipation performance, meeting the requirements for long-term and high-intensity welding operations. The layout is reasonable and the wiring is simple, providing the most "convenient" power supply support for your laser welding and cutting process.
  • Use high-quality carbon brushes and silicon steel sheets to ensure long-term stability. Choosing TND-20 means choosing the stability of the laser process, reducing rework and enabling your welding efficiency to reach a new level.

    Frequently asked questions

    We commit to 100% pure copper coil construction for all our CNC series transformers. We do not use aluminum or copper-clad aluminum alternatives. Pure copper offers significantly lower internal resistance, superior heat dissipation, and higher energy efficiency, ensuring a reliable lifespan of over 20 years under continuous heavy-duty industrial loads.

    Yes, absolutely. While a standard transformer cannot change grid frequency, our custom-engineered windings and premium silicon steel cores are designed to operate perfectly at both 50Hz and 60Hz. We optimize the magnetic circuit based on your target country's frequency to prevent overheating and voltage drops.

    Yes. This is our core strength. Through our Country-Specific Customization Service, we can design any voltage configuration you need (e.g., 380V to 220V, 415V to 380V, 440V to 200V). Just provide your local grid voltage and the input requirements of your CNC equipment, and we will customize the internal winding ratios before production.

    This is a dry-type isolation and voltage-changing transformer. It features excellent passive voltage regulation and anti-interference capabilities by isolating grid harmonics and suppressing spikes. However, if your local grid suffers from extreme, volatile fluctuations (exceeding $\pm15\%$), we highly recommend integrating our active voltage stabilizer (TND/TNS series) to ensure absolute protection for your servo systems.

    All our power equipment is manufactured under strict quality control and fully complies with international safety standards. Our products are backed by authentic CE and TUV Rheinland certifications. Each unit undergoes rigorous insulation withstand-voltage, fire-resistance, and EMC testing before leaving our facility to ensure hassle-free customs clearance and local safety compliance.

    Our transformers utilize advanced Air Self-Cooling (AN) or intelligent forced air cooling, utilizing high-grade H-class insulation materials that withstand temperatures up to $180^\circ\text{C}$. Combined with our optimized ventilation enclosure (IP20), it ensures safe, continuous 24/7 operation even in high-temperature metal processing workshops or dust-prone environments.

    Yes. Every unit undergoes advanced Vacuum Pressure Impregnation (VPI) with eco-friendly insulating varnish. This process seals the coils entirely, making them highly resilient against moisture, conductive factory dust, and oil mist typical in CNC workshops. VPI also eliminates micro-vibrations, lowering operational noise below 45dB.

    We provide a comprehensive warranty alongside 24/7 remote technical assistance backed by our 20 years of engineering experience. If your local engineers encounter layout, installation, or wiring queries, our technical team will provide step-by-step guidance via video calls and detailed English manuals to get your production line running without delay.
