主营产品：LD-A series high-energy precision welding repair machine (alias: cold welding machine, stainless steel sheet cold welding machine, imitation laser welding machine, etc.) adopts the principle of large capacitor energy storage and instantaneous pulse release, which can complete solder and welding in tens of milliseconds. The welding process of workpieces. Because the pulse time is very short (millisecond level), the pulse energy is very precise, and the residual heat transmitted to the workpiece is very small; therefore, the heat of the workpiece base is small, and no annealing or discoloration occurs outside the solder joints. Therefore, this series of products are widely used in the welding and repair of various precision workpieces, such as molds, precision castings, precision mechanical parts, thin plate parts, thin-walled parts, precious metals, copper, aluminum, etc. It also pioneered the addition of multi-waveform output, which can achieve better welding results.
