The picture shows the schematic diagram of welding machine. Who can elaborate on the meaning of each grid?

BX 1-3 15-2B (arc welding) transformer, X-shaped voltage drop characteristics, 1 moving core, 3 15 rated output current 3 15A. 2 manufacturer code, generally refers to high no-load voltage.

Below 1 ~OO ~ ~, it means that it is a single-phase input and single-phase output of power frequency alternating current. The shape of the welding handle is short circuit arcing. At right angles to the arc is a descending feature. 1-50HZ, which is 50HZ of single-phase electricity. 0 ~50HZ is the input and output of welding machine with power frequency of 50HZ. No-load voltage is 70V. U 1=380 single-phase 380V, connected with two fire lines. 70A/22.8V is the minimum current of 70A and the voltage of 22.8V. 3 15A/32.6 is the maximum current of 3 15A and the voltage of 32.6V. ..

Vertically, 35% is the load rate. Working for three and a half minutes in ten minutes and resting for six and a half minutes, the welding machine can output current of 3 15a and voltage of 32.6 v. ..

60% welding machine works for six minutes in ten minutes and rests for four minutes. The output current can reach 240 A and the voltage is 29.6 V. ..

Continuous work, output current can reach 185 A, voltage is 27.4 V,

This is usually a value not exceeding 40 degrees Celsius.

67A is the maximum input current, that is, the full load current of the welder. 37A is the input minimum current value.
