Product Introduction:
It is a semi-automatic pneumatic spot welding machine that uses intermediate frequency double head welding technology. It is designed for the welding process of 2+2+2mm carbon steel saw blades stacked in three layers (with a large middle piece and a small upper and lower piece). The upper and lower electrodes each have two welding heads, and the distance between the head electrodes can be adjusted left and right to adapt to various size specifications; Equipped with a rotary worktable, the welding process is as follows: manual feeding and starting, the machine head presses down to complete one welding, the worktable rotates 90 ° after lifting, the machine head presses down again to complete the second welding, and the cycle ends. The structure of this model is simple yet exquisite, with a novel exterior design that conforms to modern workshop aesthetics. The entire machine operates smoothly and responds sensitively, with stable and reliable welding quality. It also has multiple protection functions such as overcurrent, overvoltage, and gas shortage, ensuring high safety during use; In terms of energy consumption, the intermediate frequency inverter technology significantly reduces reactive power loss. In addition, the fixed welding machine and rotating workpiece operation mode reduce the energy consumption of moving parts, making it an ideal alternative to upgrading traditional manual welding machines as it is highly efficient and environmentally friendly.
Features:
① The welding current control accuracy is ± 1%, and the time control accuracy is ± 1ms, ensuring consistent heat input for each welding point.
② Pressure regulation with digital display and closed-loop feedback, actual pressure deviation less than 0.01MPa, stable depth of weld indentation.
③ The electrode head adopts a standard taper interface, which does not require re alignment after replacement, and the material has good thermal conductivity, with a welding point diameter variation coefficient of ≤ 3%.
④ The rotary indexing is driven by a servo motor, with a rotation angle error of less than ± 0.05 °, and the secondary welding position is completely symmetrical with the first one.
⑤ 100 pieces of continuous welding in the same batch, with a maximum difference of 5% in the tensile strength of the welding points, meeting the consistency requirements of automotive component levels.
Detailed Images:

Symmetrical double heads: Double headed symmetry, simultaneously pressing up and down, welding two points at once without deviation or virtual welding, with adjustable spacing; Rotate 90 ° for welding repair, with four points evenly and neatly arranged. The pressure and current are stable, fast, and reliable.

Workpiece rotation platform: The rotating platform automatically rotates the workpiece 90 degrees according to the program, with precise welding alignment and uniform four points; Accurate division positioning, smooth movement, and improved welding consistency.

Dual cylinders: The upper and lower heads are independently driven by dual cylinders, with adjustable pressure settings to accommodate varying thickness combinations. The downward pressing is smooth and buffered to prevent impact damage to the workpiece, while the pneumatic response is sensitive, ensuring a compact and efficient welding cycle.

Waterway components: All waterway components undergo surface treatment to prevent rusting, and waterway drainage is independently discharged to the water tank. Based on the outflow situation, blockages in the waterway can be observed and eliminated.

Welding Workpiece: The spot welder is also widely applied in various fields such as automotive components (e.g., nuts, housings, stud welding, and spot welding), home appliance manufacturing (compressor housings, electrical accessories), hardware sheet metal (iron wire products, galvanized plate assemblies), and aerospace precision parts, serving as a versatile, cost-effective industrial platform suitable for thin sheet stacking and multi-point symmetrical welding of various carbon steels, stainless steels, and galvanized plates.
