Honda 250 gasoline powered welding machine, SHU250The structure of power generation welding machines is very simple, which is a high-power transformer. Welding machines can generally be divided into two types according to the type of output power source, one is the communication power source; One type is direct current. It is made using the principle of inductance, and the inductance undergoes infinite voltage changes when it is turned on and off. It uses the high-voltage arc that occurs when the positive and negative poles are short circuited in an instant to melt the solder on the welding electrode and achieve the intention of connecting them. In fact, it is a transformer with a decreasing external characteristic, which will220Vand380VCommunication power is converted into low-voltage direct current. Welding machines can generally be divided into two types based on the type of output power source: one is communication power source; One is a powerful diesel generator welding machine with direct current function, which is designed by engineering construction teams, building contractors, and equipment leasing companies that prioritize the proven reliability. The control circuit board is placed in a sealed protective box for more reliable operation.
