This Automatic CNC C-Type Robotic Spot Welder is a high-end automated resistance welding solution for the automotive industry. At its core, it combines the kinematic flexibility of an industrial robot with the superior rigidity of a C-type welding gun, all under the precise programming and path control of a CNC system. Its revolutionary feature is the integration of a floating mechanism with automatic compensation within the welding gun, which enables real-time auto-adjustment for electrode wear and workpiece fit-up tolerances. This achieves an adaptive welding accuracy unattainable with manual or traditional mechanized welding. Designed for the high-cycle, high-quality spot welding demands of automotive bodies and chassis, it serves as a core asset for enhancing the welding quality and efficiency of body-in-white production lines, thanks to its automation, high flexibility, and exceptional repeatability.

• Intelligent Self-Adaptive Floating Gun: The welding gun incorporates a unique four-bar floating mechanism with automatic compensation. It automatically adjusts the welding position to compensate for electrode wear, ensuring constant force and precise nugget placement even with fit-up tolerances in automotive sheet metal, significantly enhancing process robustness.

• Modular High-Rigidity C/X-Type Welding Guns: Offers standardized C-type and X-type gun bodies with up to 80% interchangeability, drastically reducing spare parts inventory. The gun body features an aluminum alloy structure that is lightweight yet rigid, with electrode force up to 600kg, meeting the stringent demands of high-current welding in the automotive industry.

• Compact & Efficient Medium Frequency Welding Power: Equipped with a self-developed transformer in a compact design, offering 1000Hz and 2000Hz Medium Frequency Inverter (MFDC) power source options. The high-frequency output delivers more concentrated, controllable heat input with minimal spatter and extended electrode life, perfectly suited for automated continuous production.

• Flexible Drive & Integrated Control: The gun is compatible with either integrated electric cylinders or combined servo electric cylinders for precise, fast-responding force application. The entire system is coordinated by a CNC robot controller, enabling fully automated, programmable management of welding paths, parameters, and sequences, with easy changeover and maintenance
