The correct use of spot welding machine

1. When welding, the position of the electrode rod should be adjusted first, so that when the electrode is just pressed to the weldment, the electrode arms remain parallel to each other.

2, the selection of current adjustment switch series can be selected according to the thickness and material of the weldment. After power on, the power indicator light should be on, and the electrode pressure can be adjusted by changing the compression degree of the spring pressure nut.

3. After the above adjustment is completed, the cooling water can be switched on first and then the power supply can be switched on for welding. The procedure of the welding process: the weldment is placed between the two electrodes, step on the pedal, and make the upper electrode contact the weldment and pressurize it. When the pedal is continued to be pressed, the power contact switch is turned on, and the transformer starts to work. The secondary circuit is energized to heat the weldment. When the electrode rises when the pedal is released after welding for a certain period of time, the power supply is cut off first and then restored to its original state by the pulling force of the spring, and the single point welding process is over.

4, weldment preparation and assembly: all dirt, oil stain, oxide scale and rust shall be removed before welding steel weldments. for hot rolled steel, it is better to pickle, sand blast or remove oxide scale with grinding wheel. Although the uncleaned weldment can be spot welded, it seriously reduces the service life of the electrode and reduces the production efficiency and quality of spot welding. For medium and low carbon steel with thin coating, it can be directly welded.
