1. When welding, adjust the position of the electrode rod so that the electrode arms are kept parallel to each other when the electrode is pressed to the weldment.
2. The selection of the number of current adjustment switches can be selected according to the thickness and material of the weldment. After the power is turned on, the power indicator light should be on, and the electrode pressure can be adjusted by adjusting the spring pressure nut to change the degree of compression.
3. After completing the above adjustment, you can turn on the cooling water before turning on the power to prepare for welding. Procedure of the welding process: the weldment is placed between the two electrodes, the foot pedal is depressed, and the upper electrode is brought into contact with the weldment and pressurized. When the foot pedal is continuously pressed, the power contact switch is turned on, and the transformer starts to work secondary. The loop energizes to heat the weldment. When the pedal is released after a certain time of welding, the electrode rises, and the power is turned off by the tension of the spring to return to the original state, and the single-point welding process is finished.
4, weldment preparation and assembly: steel weldments must be cleaned of all dirt, oil, scale and rust before welding, for hot-rolled steel, the weld is first pickled, sandblasted or removed with a grinding wheel. Uncleaned weldments can be spot welded, but severely reduce the life of the electrode while reducing the efficiency and quality of spot welding. For medium and low carbon steel with thin coating, it can be directly welded.
USB 3.0 is the future and the new generation in transmission tech, with the following advantages: Super speed – It`s 10 times faster than its predecessor and backward compatible with all USB 2.0 interfaces. It uses a 9-pin connector with 4 pins compatible with USB 2.0 and another 5 pins for bi-directional data transfer.
External Differences
The USB 3.0 connector is blue.
The top 5 pins provide the two-way data transfer.
The bottom 4 pins provide backward compatibility with USB 2.0.
Note: All USB 3.0 Interfaces are blue
