Automatic Pneumatic Gantry Medium Frequency Multi Head Spot Welder Sheet Metal

This Automatic Pneumatic Gantry Medium Frequency Multi-Head Spot Welder is an industrial high-efficiency welding platform based on Medium Frequency Inverter (MFDC) technology, engineered for the high-quality, high-efficiency multi-point/full-row synchronous projection welding of sheet metal. Its core features a robust gantry frame integrating multiple independently pneumatic-actuated electrode heads and dedicated square planar electrodes. It can complete multiple weld spots synchronously in a single cycle, delivering the core advantages of medium frequency welding: minimal spatter, low thermal distortion, and extended electrode life. Leveraging its MFDC DC output characteristics, combined with programmable fully automatic control and force adjustment, it ensures exceptional consistency and reliability for every weld spot in the batch production of sheet metal components like automotive bodies and enclosures. It is a professional solution for boosting the throughput and quality of welding large, flat workpieces.

• High-Efficiency MF Inverter Power Source: The main circuit employs advanced Medium Frequency Inverter (MFDC) technology. Compared to traditional AC welding, it offers significant advantages: stable welding current, concentrated heat input, minimal spatter, energy savings, and low electrode wear, providing ideal energy for high-quality sheet metal welding.

• Pneumatic Gantry Multi-Head Structure: Features a high-rigidity gantry frame equipped with multiple independently pneumatic-actuated electrodes. The force and stroke of each electrode group can be individually and precisely adjusted, ensuring uniform and consistent pressure across multiple spots on large workpieces for high-efficiency synchronous welding in one cycle.

• Fully Automatic Intelligent Control: Utilizes a microprocessor-based fast-response touch controller for fully digital control with an intuitive interface. It includes automatic detection and compensation functions to effectively prevent cold welds and insufficient fusion. Foot switch control is supported for high productivity and low labor intensity.

• Precise Adjustable Force & Motion: Electrode force is applied via compressed air, offering stable and adjustable pressure. The descent and ascent speeds of the pressure head are independently and infinitely adjustable, enabling cushioned contact with the workpiece to effectively reduce impact, protect the workpiece, and lower operational noise.

• Safe & Reliable System Design: The secondary conductor uses an upper insulation method for stable and reliable insulation performance. The machine integrates necessary safety interlocks and monitoring, built with a robust structure designed for continuous, high-duty-cycle automatic production environments
