The power of the medium frequency spot welding machine transformer load is certain, and the power is proportional to the current and voltage. Lowering the voltage will increase the current. The spot welding machine is a special working method of the step-down transformer.
The medium frequency spot welding machine uses a large current to pass through the resistance of the workpiece itself and release the resistance as well as the contact resistance between the electrode and the workpiece to generate heat to form a weld nugget, and apply a certain pressure to solidify and stabilize the weld nugget. So the parameters are mainly controlled by current, time and pressure. Because the secondary voltage of the spot welding machine is very low and the resistance of the human body is very high, the current will not flow through the human body.
Test welding, turn on the cooling water and then turn on the power supply to prepare for welding. The current is adjusted to be tested sequentially from small to large to avoid excessive current from damaging the electrodes and equipment parts. The welding process: Place the workpiece between the two electrodes, touch the switch, and complete the sequential welding. Note that the panel switch is placed in the single-point position during the trial welding. , touch the play switch and lift it quickly.
