【 Auto cooling fan 】 Use is too big.
when the car is the use of the positive and negative poles in instantaneous short circuit arc produced by high temperature to melt the solder on the welding electrode and welding materials, to achieve the purpose of make them combine. Structure is simple, it is a large power transformer, car generally according to the output power types can be divided into two kinds, one kind is ac power; Is a kind of direct current. Is made by using the principle of inductance, inductance in the on and off will produce a great voltage change, using positive and negative poles in instantaneous short circuit when the high pressure arc to melt the solder on the electrode, to make them achieve the goal of atoms. And a cooling fan is put in the car, which make its produce a greater role, working hours and more durable.
