The inductive reactance of a primary coil is much larger than the value of load resistance converted into the primary;
变压器原边线圈电感的感抗远远大于负载电阻对原边的折算值；
The variety of current can be automatic compensated caused by undulating of voltage & secondary loop inductive reactance.
对焊接电流进行反馈恒流控制，自动补偿网压波动、二次回路感抗变化对焊接电流的影响；
This situation occurs because noise cancellation depends on the fact that the inductive reactance of the windings must be much larger than the impedance of the cable.
线圈的感应电抗必须远大于电缆阻抗，噪声抵消导致这个情形出现。
