1. The first thing we need to understand is the type of welding power source of the spot welding machine you are buying, and how much welding current is the welding power supply?
I believe that when you buy a spot welding machine, the manufacturer will tell you what is the maximum thickness of the welding nickel sheet, but it is not ruled out that some manufacturers exaggerate their own machines and tell you that they are false welding thicknesses. Then try to try the welding effect of the machine with our products before buying the machine.
5000A transistor spot welding machine welding maximum thickness 0.2mm (reference value)
The transistor welding power supply is the best of all welding power sources, its discharge current is the most stable, and the waveform control is the most accurate. The unstable discharge current of the welding power supply will lead to the occurrence of undesirable phenomena such as virtual welding, missing welding, and explosive welding.
At this point, you can go to understand how large the discharge current of the purchased spot welding machine, because the size of the welding current determines the thickness of the machine's welding nickel sheet.
2. Adjust the parameters of the spot welding machine and the pressure of welding
Spot welding machine transistor welding power supply, high-definition display, real-time monitoring of welding waveform, convenient and intuitive adjustment parameters
The main adjustment parameters are voltage and current, welding time.
Thin nickel sheets need to reduce the current, and thicker nickel sheets need to adjust the current.
According to the material adjustment parameters of the nickel sheet, there are two common welding materials on the market, pure nickel and steel nickel plating, pure nickel material has small resistance, after the current arrives, the energy loss is large, so it is necessary to adjust the current for welding. Nickel-plated steel, on the other hand, is easy to weld.
Adjust the parameter data according to the thickness and material of the nickel sheet.
The amount of pressure in the welding is also crucial, and the adjustment of the pressure can change the resistance.
Based on the above to adjust the welding capacity of the spot welding machine according to the thickness and material of the nickel sheet, then the welding effect will be doubled with half the effort.
3. Another point to remind everyone is to keep the surface of the welded product clean and oil-free, and regularly polish the welding surface of the welding pin, otherwise it will hinder the full arrival of the welding current.
