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 on the weldment, the electrode arms should be parallel to each other.
2. The number of current adjustment switch stages can be selected according to the thickness and material of the weldment. After energizing, the power indicator should light up, and the electrode pressure can be adjusted by the clarinet pressure nut to change its compression degree.
3. After finishing the above adjustment, you can turn on the cooling water first, and then turn on the power to prepare for welding. The procedure of the welding process: the weldment is placed between the two electrodes, and the pedal is stepped on to make the upper electrode contact the weldment and pressurize it. When you continue to press the pedal, the power contact switch is turned on, the transformer starts to work, and the secondary circuit is energized to heat 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 spring to restore the original state, and the single-point welding process ends.
4. Preparation and assembly of welding materials: Before welding steel welding materials, dirt, oil stains, oxide scale and rust must be removed. For hot-rolled steel, it is best to use pickling, sandblasting or grinding wheels to remove the oxide scale at the weld. Welding materials that have not been cleaned can be spot welded, but the electrode life is greatly reduced, and the production efficiency and quality of spot welding are also reduced. For low- and medium-carbon steel with thin coatings, it can be welded directly.
