The lithium battery spot welder adopts the principle of double-sided two-point over-current welding. When working, the two electrodes pressurize the workpiece to make the two layers of metal form a fixed contact resistance under the pressure of the two electrodes. When the welding current flows from one electrode to the other electrode, a transient hot flame connection is formed at the two contact resistance points, and the welding current can flow from the other electrode along the two workpieces to form a loop to the electrode, And the internal structure of the welded parts will not be damaged.

The manual spot welder cleans the surface of the weldment. After the assembly is accurate, it is sent between the upper electrode and the lower electrode to apply pressure to make good contact; The contact surface of the two workpieces is heated by power on, and local melting occurs to form nugget; After power failure, the pressure is maintained to make the flame core cool and solidify to form solder joint; Remove the pressure and take out the workpiece. Welding parameters such as welding current, electrode pressure, power on time and electrode working surface size have great influence on welding quality. The high temperature arc generated by the short circuit between the positive and negative poles is used to flame the material to be welded between the electrodes, so as to achieve the purpose of combining them. Because manual, the price is cheaper and the efficiency is average.

Scope of application: spot welder is widely used in metal cabinet manufacturing, construction machinery repair, auto parts, bicycle parts, special-shaped standard parts, crafts, electronic components, instruments, battery spot welding, hardware spot welding, electrical switch, cable manufacturing, filter, muffler, metal packaging, chemical containers, wire mesh, net basket and other metal products industries.

Automatic spot welding machine: after setting the parameters and fixing the lithium battery on the lithium battery fixture, the lithium battery spot welding machine will weld the lithium battery according to the set parameters, and the automatic spot welding machine adopts the motion controller to support the rapid programming of array and non array battery packs. Support breakpoint startup, automatic startup and manual startup mode conversion. It has its own current welding inspection monitoring alarm, which can effectively solve the phenomenon of false welding and false welding. The welding electrode energy can be switched during operation. Because it is automation equipment, the efficiency is relatively high, of course, higher than the price of manual equipment.

Scope of application: automatic spot welding machine can only produce relatively high power lithium battery, sightseeing car battery, electric motorcycle battery, power battery module, power tool battery, garden tool battery.

It depends on your personal situation and what type of battery you produce. You should have your own budget and positioning. This is the key point. How much money you spend to solve your welding problems or meet your production needs basically determines the direction you choose. With the direction, in the process of selection will not waste time and energy.
