Used IPG Fiber Laser Sources

The DMK Repair Center maintains a long-term inventory of a large number of used IPG (IPG Photonics) fiber laser sources. With a complete range of models and stable supply, all units undergo professional inspection and maintenance by experienced engineers, delivering stable performance and sufficient output power. They are a highly cost-effective choice for laser equipment fault repair and old-machine upgrading.

Technical Condition & Quality Assurance

All used IPG lasers, upon arrival, undergo a complete standardized inspection process to ensure every shipped unit meets production standards: output power calibration using a professional power meter to verify full-range output and ensure rated power compliance with stable power fluctuation; beam quality analysis to verify beam mode and spot quality, ensuring normal cutting performance; optical path coupling inspection to check internal optical paths, combiners, and gain fiber, eliminating potential power degradation; cooling system testing to verify water-cooling circuits, temperature sensors, and cooling fan operation; communication function verification to test compatibility with mainstream laser cutting system communication protocols, ensuring plug-and-play operation; and internal module inspection to check pump sources, power modules, and control boards item by item, with any aged or defective components replaced without exception.
