Introduction：
Are spot welding machines and electric welding machines the same product? Many people make mistakes about this! Spot welding machine and electric welding machine are not the same product, why do we say that? Because one uses an electric arc to melt the welding rod for welding, and the other uses resistance heat to melt the base material for welding, let's explore together with Heltec!
Main differences
The household battery spot welding machines on the market are divided into battery and capacitor models, which are different from the intermediate frequency spot welding machines used in workshop factories. Household battery spot welding machines and capacitor energy storage spot welding machines are mostly used to assemble 18650 lithium battery packs. For example, when the batteries of some electric maintenance tools are not durable, they can be assembled and replaced by themselves; Mobile phone batteries are not durable and can be transplanted with battery spot welding machines; Some high-precision experimental equipment can be repaired and welded with spot welding machines.
The battery spot welding machine can weld various metal materials such as stainless steel, iron, nickel plating, pure nickel, aluminum, aluminum alloy, tungsten, etc. The usage method is also relatively simple, suitable for home maintenance, DIY electronic electricians, and is also an essential tool for professional maintenance.
Electric welding machine, also known as welding machine, uses welding rods to connect metal materials. The arc generated by its work is very hot, and protective tools should be worn during use to avoid burns. A certain level of operational knowledge and experience is required. Non professionals need to undergo professional training before they can complete their assignments. In factories, electric welding machines are used to weld steel frames or other objects. When the welding material is large enough, it is often necessary to choose a good welding machine.
Different welding principles
The battery spot welding machine adopts the principle of double-sided double point overcurrent welding. During operation, the two electrodes apply pressure to the workpiece, causing a certain contact resistance between the two layers of metal under the pressure of the two electrodes. When the welding current flows from one electrode to the other electrode, an instant thermal fusion is formed at the two contact resistance points, and the welding current instantly flows from the other electrode along the two workpieces to this electrode to form a circuit, without damaging the internal structure of the welded workpiece.
Electric welding machine uses the high-temperature arc generated by the instantaneous short circuit between the positive and negative poles to melt the solder and the material to be welded on the electrode, in order to bond the objects in contact. Its structure is very simple, just a high-power transformer. Welding machines can generally be divided into two types based on the type of output power source: AC power source and DC power source;
