Product Introduction:
The dual-head capacitor discharge projection welding workstation is purpose-built for high-strength, high-demand hardware welding. The automatic resistance welding machine adopts a sturdy aluminum profile frame and fully enclosed acrylic protective panels, and is equipped with an emergency stop button and air filter to ensure absolute safety during operator use. The core components include a pneumatic-hydraulic booster cylinder and independent pressure regulating valves, ensuring that the pressing depth and pressure output of the left and right welding heads are stable and consistent, thereby preventing cold welds. Left and right dual vibratory bowl feeders provide automatic feeding, with manual-assisted part loading, while a PLC touch screen enables precise setting of discharge energy and action sequence. Whether considering the durability of the mechanical structure or the discharge stability of the capacitor power supply, this equipment can operate stably over the long term in complex workshop environments, delivering perfectly consistent carbon steel buckle clamp finished products.
Features:
1.Two-hand start/emergency stop protection: Can be equipped with optional two-hand anti-crush start buttons. Together with the prominent red emergency stop button on the panel, it can instantly cut off the power supply in an emergency, complying with industrial safety standards.
2.Low smoke, dust, and spatter: The short-time discharge characteristic of capacitor-discharge welding greatly reduces high-temperature vaporization of welding materials and spatter, improving workshop air quality and reducing harm to employees’ respiratory tracts and eyes.
3.Tri-color warning light status display: The top of the machine is equipped with red, yellow, and green lights, making it clear at a glance whether the equipment is in normal operation (green), waiting for material (yellow), or in fault alarm (red), facilitating workshop safety management.
4.Effective isolation of noise sources: Precision mechanical fits and cylinder buffering design greatly reduce the mechanical impact noise when the cylinder presses down and lifts, creating a relatively quiet working environment for the workshop.
Welding Test:


Welding Workpiece: From tabbed steel clamp rings and pipe hoops to exhaust clamps, hose clamps, pipe clamps, tab clamps, metal fastening rings, and U-clamps, this equipment broadly accommodates various ring-shaped hardware components. Utilizing a dual-head, step-by-step capacitor discharge projection welding process, it easily handles carbon steel, galvanized steel, or stainless steel parts with custom stamping tabs. By perfectly solving the thin-walled ring welding pain points of thermal deformation and excessive spatter, it serves as a highly suitable mass production solution for the hardware fasteners, automotive parts, home appliance assemblies, and pipeline engineering industries.
Detailed Images:

Dual independent welding joints and upper and lower electrodes: Dual heads press step-by-step with uniform force and zero deviation; high-conductivity copper electrodes ensure rock-solid welds at both ends.

Pneumatic-hydraulic intensifier cylinder: Super thrust presses instantly without bouncing, completely eliminating cold and missed welds from the source.

Left and right double vibration discs and feeding mechanism: Dual vibratory feeders automatically sort and feed parts, eliminating manual grabbing, saving labor, and boosting cycle times.

Energy storage welding control box: Large capacitors discharge in milliseconds with concentrated heat and low spatter, completely preventing thin-wall deformation and annealing.
