product description

Core Product Advantages

1. Dual Independent Welding Station Design Equipped with two separate pneumatic welding cylinders and copper electrode assemblies, the machine can simultaneously complete two sets of welding points on PV brackets in a single cycle. It drastically cuts down single-piece processing time and greatly boosts daily production throughput for solar bracket production lines.
2. High-Efficiency Intermediate Frequency Inverter Welding System Intermediate frequency DC power supply outputs concentrated, controllable welding current. Compared with traditional AC spot welders, it features lower energy consumption, smaller welding spatter, and stronger solder joint tensile strength. Welds on galvanized steel solar brackets avoid zinc layer burning and cracking, guaranteeing anti-corrosion performance of finished brackets.
3. Intelligent PLC Touchscreen Control System Human-machine interface touch panel with independent parameter storage for different PV bracket models. Operators can freely adjust welding current, pressure, holding time and cooling delay. Real-time fault alarm, production counting and data recording functions simplify production management; the three-color signal light clearly displays running, standby and fault status.
4. Precision Positioning Fixture for Solar Brackets Customized quick-locking positioning mold is built for standard PV support profiles. Pneumatic clamping mechanism automatically fixes workpieces to eliminate displacement during welding, ensuring uniform weld position accuracy for every bracket. The fixture base supports flexible replacement to adapt multiple specifications of photovoltaic brackets.
5. Sturdy Integrated Frame & Safe Operation Configuration Heavy-duty cast steel machine frame effectively absorbs welding vibration and maintains long-term machining precision. Equipped with anti-slip adjustable foot pads for stable placement on workshop floors. Foot pedal switch with safety protection sensor prevents accidental startup and meets industrial safety operation standards.
6. Complete Water-Cooling & Stable Pneumatic Circuit System Built-in circulating water cooling unit continuously cools copper electrodes and transformers, sustaining long-hour non-stop production. Standardized pneumatic valve group with pressure regulating valves provides stable welding pressure, free from air pressure fluctuation interference in factory workshops.
