The correct use of spot welding machine

spot welding machine correct use method

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

2. The selection of the number of current adjustment switch stages can be selected according to the thickness and material of the weldment. After power on, the power indicator should light up, and the electrode pressure can be adjusted to the single spring pressure nut to change its compression degree.

3. After the above adjustment is completed, the cooling water can be turned on first, and then the power supply can be turned on to prepare for welding. The procedure of the welding process: Place the weldment between the two electrodes, step on the pedal, make the upper electrode contact the weldment and press. When you continue to press the pedal, the power contact switch opens, the transformer starts to work, and the secondary circuit heats the weldment. After welding for a certain period of time, when the pedal is released, the electrode rises, and the power is cut off by the tension of the spring and returns to its original state, and the single-point welding process ends.

4. Preparation and assembly of welding materials: Before welding steel welding materials, dirt, oil, scale and rust must be removed. For hot-rolled steel, it is best to use pickling, sandblasting or grinding wheels to remove the scale of the weld. The uncleaned welding material can be spot welded, but the electrode life is greatly reduced, and the production efficiency and quality of spot welding are also reduced. For medium and low carbon steel with thin coating, it can be directly welded.
