IDP8210 precision spot welding machine 8000A

IDP-8210 is a high-precision spot welding machine with 6 control modes and 5 optional operating frequencies (1KHz/2KHZ/3KHZ/4KHZ/5KHZ). It is the first servo motor control function in the industry to achieve precise adjustment of multi-stage welding pressure and adjustable welding head reset distance, solving the problem of instantaneous impact force when the cylinder welding head comes down.

1. 8-inch high-definition touch screen, with built-in detector function, real-time display of welding current, voltage, power, resistance waveform and corresponding welding data, rich and intuitive display content, simple and easy to understand.

2. Fixed peak current, fixed secondary current, fixed secondary voltage, fixed power, fixed pulse width, mixed control and other control modes.

3. Built-in multiple fault diagnosis, welding protection function, and monitoring alarm function to ensure welding safety.

4. Rich I/O interface, support multiple communication protocols (RS-232, RS-485, Ethernet, etc.), convenient for external automation control.

5. Support welding record storage and fault information storage, real-time export and reading of U disk, convenient for quality monitoring and quality tracking.

6. Support upper and lower limit monitoring settings of current, voltage and power. If the output exceeds the set upper and lower limits, an alarm prompt will be given.

7. Support multi-stage discharge, set slow rise and slow fall functions, which is helpful for welding forming and effectively solves welding spatter, ensuring welding stability.

8. 32 sets of parameter storage, convenient for multi-variety welding (expandable).

9. 1K/2k/3k/4k/5k frequency is adjustable, with high control response and precision, suitable for a variety of complex welding conditions.

1. Influence of welding current

The influence of current on heat generation is greater than that of time and pressure. Therefore, it is a parameter that must be strictly controlled during the welding process. If the welding current is too small, the core cannot be formed or the core size is small, and the strength of the weld is small; if the welding current is too large, it will cause overheating, spattering, and deep indentation of the welded workpiece.

2. Influence of welding time

In order to ensure the core size and weld strength, the welding time and welding current can complement each other within a certain range. In order to obtain a weld of a certain strength, a large current and a short time (strong condition, also known as hard specification) can be used, or a small current and a long time (weak body condition, also known as soft specification) can be used.

3. Influence of electrode pressure

Electrode pressure has a significant effect on the total resistance between the two electrodes. When the electrode pressure is small, spatter is easy to occur. As the electrode pressure increases, the total resistance decreases. When the electrode pressure increases and the welding current remains unchanged, the reduction in heat generation caused by the reduction in total resistance cannot be compensated. Therefore, the strength of the weld decreases with the increase in welding pressure. The solution is to increase the welding current while increasing the pressure.

4. Influence of electrode shape and material properties

Since the contact area of ​​the electrode determines the current density, and the resistivity and thermal conductivity of the electrode material are related to the generation and loss of heat, the shape and material of the electrode have a significant impact on the formation of the weld nugget. As the electrode tip deforms and wears, the contact area increases and the strength of the weld spot decreases. Pay attention to the maintenance and trimming of the electrode (spot welding head) during use.
