Introduction to the characteristics of spot welding machine and welding principle

　　The spot welding machine adopts the principle of double-sided double-point overcurrent welding. When working, the two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under pressure, and the welding current flows from one electrode to the other electrode.

　　Instantaneous thermal welding is formed on the two contact resistance points at all times, and the welding current flows from the other electrode to the electrode quickly along the two workpieces to form a loop without damaging the internal structure of the welded workpiece.

　　1. DTN series pulse spot welding machine has some spot welding and spot welding functions, and it has a wide range of applications;

　　2. Adopting adjustable stroke cylinder and fast solenoid valve, easy operation, fast welding speed, energy saving and consumption reduction, and improving production efficiency;

　　3. The controller adopts digital display, which is intuitive and easy to operate;

　　4. It has the function of saving power-off record data, and it will not be lost after power-off for ten years;

　　5. Special welding resistance transformer is adopted, silicon steel sheet has high magnetic permeability, internal forced water cooling production process, strong output power and high temporary load rate.

　　6. Using microcomputer control, 4/15 sets of welding specification data can be stored, and different welding data can be stored in different specifications, which is very convenient to realize precise welding of different products;

　　7. The secondary discharge mode greatly increases the welding range of the product, and can preheat or temper special materials;

　　8. With error self-detection function, various abnormal conditions can be displayed in detail, which helps to quickly eliminate abnormal conditions;

　　9. With the function of voltage data detection during welding, you can easily understand the voltage fluctuations during welding.
