Step Double Pulse Welding Machine (Hotbar)

Step double pulse welding machine (Hotbar) - meets the precise welding requirements for high-end products

In this method, current is applied to the welding object while pressure is applied, and the generated Joule heat is used for welding. Traditional manual soldering is prone to short-circuit with tin, especially for products with thinner wires and dense circuits. Comparing with manual welding, it can effectively:

       1.  Improve welding quality, such as a solder bridge problem
       2.  Save costs, for instance, free from scrapped products
       3.  Work efficiently, for example, laborsaving

Hotbar multi-function welding machine

This machine is multifunctional welding machine, applicable to welding for a variety of high-end precision products, such as: DP, Mini-DP, HDMI-A, C, D, PCB‘A, USB 3.1 (USB Type-C), USB4 welding for connector and welding for wires, SlimSAS cable/MiniSAS cable; and one-side/two-sides welding for many other high-end precision products. The machine works in high efficiency, has excellent quality and outstanding stability.
