Product Name: 3 Phase Pneumatic Medium Frequency Projection Welder Galvanized Stainless Steel
Product Description

This Heavy-Duty High-Efficiency Medium Frequency Stationary Spot Welder is a fully automated projection welding solution engineered for the high-consistency, high-volume production of automotive piston rod assemblies. Integrating a Medium Frequency Inverter (MFDC) welding power source, servo/proportional valve precision force control, a dual-path automatic feeding system for rods and rings, and an intelligent HMI, it forms a complete high-performance welding workstation Made in China. Its Medium Frequency DC output ensures a welding process with minimal spatter and concentrated heat input, achieving exceptional production efficiency while significantly reducing electrode wear and energy consumption. Optimized for materials like galvanized sheet and stainless steel, it reliably performs projection welding of piston rods to retaining rings. It is a professional High-Efficiency Medium Frequency system designed to enhance the automation level and quality consistency in manufacturing core components for automotive suspension and steering systems.

Main Features
  • High-Precision Welding Force Control: Utilizes servo drive or proportional valves for precise electrode force adjustment (±1% accuracy), fundamentally ensuring consistent pressure for every weld spot and delivering exceptionally high repeatability in weld quality.

  • Smart Automation Ready: Features self-loading mechanisms for both rods and retaining rings, enabling continuous high-speed welding. This plug-and-play automation design can cut production cycle time by nearly half while guaranteeing consistent quality.

  • Intuitive Welding Management: Saves multiple customized welding programs (force/power/duration settings) for different rod specifications, allowing seamless switching with a single command. The system continuously monitors weld integrity and alerts operators to any irregularities via visual/audible warnings.

  • Broad Operating Range & Durability: Capable of welding piston rods of various sizes. The fully water-cooled design ensures stable performance of key components even in high-temperature conditions, supporting long-term, reliable operation.

  • Comprehensive Safety & Maintenance Design: Built-in sensors provide real-time monitoring of air and water pressure, with automatic shutdown for protection if pressure drops too low. The modular design allows for quick and easy component replacement, minimizing downtime
