Fig. 2 is the utility model fundamental diagram in use.

In conjunction with the accompanying drawings its structure and operation principle are further described:

As shown in Figure 1: this multi-functional transformer has one group of square sections core 1, and the center of iron core upper and lower side is processed with screwed hole respectively, and screw mandrel 2 connects two holes, can make rotation displacement up and down.The first half of iron core, and be wound with one group near the upper end of iron core and be used to provide submerged-arc welding and exchange the low-voltage line bag 3 that welds.The latter half of iron core, and close iron core lower end is wound with one group of low-voltage line bag 5 that is used for plasma cutting, argon arc welding and direct current weldering.Be wound with high-voltage line bag 4 on the iron core between low-voltage line bag 3 and the low-voltage line bag 5, the high-voltage line bag is fixed in the centre position of screw mandrel 2 by a block frame formula insulation board 7.Wherein high-voltage line bag 4 is identical with the overall dimension of low-voltage line bag 3, and they are the magnet combination; The intermediate hollow part of high-voltage line bag 4 overall dimensions after less than the 5 coiling moulding of low-voltage line bag, they close for the line toe-in.The iron core upper and lower side is fixing by framework 6 respectively, then low-

voltage line bag

3,5 also is separately fixed on the upper and lower framework 6.As shown in Figure 2: a pair of line bag of B3 mesolow line bag 3 can do according to the difference of required voltage serial connection or and connect, if when output is done in a, d or b, c end serial connection back, can satisfy exchanging electric welding voltage, if a, b are with after c, d are connected respectively, promptly and when connecing the back and doing output, can satisfy submerged arc welding voltage.One tap f is arranged in the middle of low-voltage line bag 5 windings among the B2,, satisfy plasma cutting operating voltage needs if low pressure bag e, g hold when connecting; When if e, f end connects, be the voltage that needs of direct current weldering and argon arc welding machine.

This multi-functional transformer operation principle in use: as shown in Figure 1, 2: high-voltage line bag 4 is inserted single-phase or three-phase alternating current (380V), behind the B1 in external circuit (current limliting remittance road transformer), just produce powerful alternating magnetic field in the iron core 1, thereupon, corresponding no-load current just appears in low-voltage line bag 3 and the low-voltage line bag 5, voltage in the low-voltage line bag 3 is 30～70V, it is the floating voltage of A.C. welder, when outer circuit (i.e. weldering crust W1) incoming transport weldering connecting line (i.e. weldering crust line), can carry out the work, row is executed various interchange welderings.Change down if will have the screw mandrel of high-voltage line bag 4, when making high voltage package transfer to ultimate range away from low-voltage line bag 3, the electric current minimum in the low-voltage line bag 3 can be carried out the welding work of less electric current.Grasp the spacing of line bag 4 and line bag 3, the electric current on the line bag 3 can transfer to maximum by minimum.Thereby satisfy the multiple needs under the various situations of people.Because line bag 3 adopts magnet to combine with line bag 4, the electric current of secondary induction is not only stable but also an amount of.Impact less, splash less, electric arc is steadily constant, not current interruption, main frame does not generate heat in working long hours, result of use is good.If last commentaries on classics leading screw, when line bag 3 was engaged fully with line bag 4, it is maximum that the electric current on the line bag 3 reaches, referring to Fig. 2, a in the winding wire bag 3, b end and c, d end are connected back (promptly and connect afterwards) respectively, about the maximum current 500A that need use in the time of can obtaining the submerged-arc welding of maximum.At this moment the steel of φ about 40 can be passed through electrode W2 submerged arc to welded together.A, d or b, c end are connected as output respectively, can do general interchange weldering.General main frame has been set up control switch outward, so that people's normal running is selected, makes organisation of working reach standardization.In addition, high-voltage line bag 4 is come downwards to lower dead center by screw mandrel, even line bag 4 enters in the line bag 5, this moment, zero load of line bag 5 windings was ceiling voltage 180V～365V, can enter plasma cutting.Line holds group 5 outputs and inserts external circuit (rectifier) L, this moment, the direct current plasma arc caused by external circuit striking device B, made cutting gun W3 and ground wire radiate plasma arc, the cutting beginning, during cutting, screw mandrel 2 must come downwards to lower dead center, must not become flexible, and also can not stop at intermediate point, because the electric energy of plasma cutting work should possess good alternation sinuso sine protractor, the 50HZ frequency is immutable, otherwise cut quality and speed will be damaged greatly.Have only when argon arc welds, screw mandrel can be gone to and make line bag 4 and line bag 5 adjust to any one position of required big or small electric current, because of the argon arc welding operating voltage is lower than more than one times (95～150V) than plasma killer voltage.See Fig. 2, disconnect e, g connection in the low-voltage line bag 5, and connect e and tap f end, voltage after the rectification is (95～150V), and more stable operating current is arranged, and simultaneously welding gun and feed in the air flue 2.5～5 centimetres argon gas on the joint of cutting gun changes the outfit just can carry out argon arc welding.Directly insert direct current weldering crust W4 at rectifier L output, can carry out the direct current welding.
