In order to reduce the difficulty of processing of third layer coil, further, the third layer coil uses flexible cable coiling.

In summary, the utility model has the advantages that：(1) the utility model overall structure is simple, is easy to reality Existing, cost is low, and the utility model by the second layer coil for forming the first winding by being wrapped in first layer coil and third layer line Between circle, i.e., the winding of a layer line circle is pressed from both sides using two layers of coil, such a winding can increase the efficient coupling area between coil, Mutual inductance reactor leakage inductance can be reduced, lift the performance of reactor, and then be advantageous to the popularization and application of AC-DC argon arc welding machine.

(2) the utility model is individually turned under DC state by the second winding, because the second winding by first layer coil with Third layer coils from parallel connection of coils is formed, i.e., using two coils, has larger sectional area, be avoided that temperature rise is too fast and influences reactor Performance.

(3) the utility model replaces traditional mutual inductive type reactor by the way of four sets of coils are in parallel two-by-two, only needs Will on skeleton the layer line circle of coiling three, reduce assembly process, reduce the risk of coil connectors short circuit, can effectively improve production Efficiency and product quality, reduce management cost.
