焊机制作方法（Welding machine making method） Production method: Welding request top Specific method is: Find a oneself or around a one kW transformer, secondary 1 cm wide copper wire winding, the output voltage of about 12 volts, the output current of 100 or more. The speed regulating circuit of the vacuum cleaner is made up of an electronic voltage regulator, which is connected in series at the primary level (also available as 2 kW manual voltage regulator). It is used to adjust the current and weld the pipes of different thickness, Pliers, homemade carbon blocks, carbon brushes for motors, or carbon bars for old communications batteries According to the experiment, the secondary current of the 6 tubes is only about 65 40 square iron core in a short time (temporary load rate of 35%) up to 180A, daily enough. You can use the following method to wrap it up. Turns per volt by 1 turns The first pole 220*1 = 220 turns is connected by 380 volts in 165 turns. No, 380V can do without The first pole taps everywhere in the 0-15-30-45-60---------------------------230----------385, I, II, III., IN,.NI, 220V, 380V Changing the position of the 1-5 taps can adjust the magnitude of the sub pole output current. The first pole is wrapped around the core of one side, and the outside is insulated. Sub pole 46*1 = 46 turns Sub coil winding method is exquisite, first in the first pole coil winding 18 laps. The rest 28 laps around another core. The initial pole diameter is not less than 5 square copper wire, and the secondary pole diameter must be more than 16 square copper wire. The line diameter is too small, the impedance is too large, the arc is instantaneous The pressure between the two will be large, it is difficult to arc Core cross section (S) S=AxB (cm2) Voltage per turn (E) E=4.44FBS*0.0001 (V/ turns) F=50HZ (power frequency) B=1.1T-1.5T (magnetic saturation induction of silicon steel sheet) Primary coil turns: N1=U1/E (turns) U1, usually 220V or 380V Two turns: N2=U2/E (turn) U2, usu
