Be all single welding function in existing double tube positive exciting formula topological structure inverter type welder at present, also do not realize the different welding function of MMA manual welding, TIG argon arc welding and Plasma plasma cut three kinds in the welding machine of one simultaneously.A tractor serves several purposes not only brings conveniently to user, and greatly reduces the input cost of welding equipment.
Due to the difference of welding procedure characteristic, the reactor that the mode of transformer pressure-reducing that what MMA manual welding, TIG argon tungsten-arc welding adopted is obtains 60-80V voltage and small sensible weight realizes the welding of low-voltage and high-current, and the reactor that the mode of what Plasma air plasma cutter then needed to adopt is transformer boost obtains 300V-500V voltage and large sensibility reciprocal realizes the cutting of high voltage small area analysis.Three functions are combined on a machine, just need the secondary side of main transformer under different functional modes, be operated in the state of step-down or boosting; Under out put reactor is operated in little sensibility reciprocal and large sensibility reciprocal; And export rectification fast recovery diode and be operated in the low withstand voltage and withstand voltage situation of height to realize different welding functions.

When using two-tube single-ended forward type inverter type welder provided by the invention to realize the circuit of multi-functional welding, when pwm pulse opens driving simultaneously, IGBT switching tube Q1 and IGBT switching tube Q2 conducting simultaneously, electric current flows through IGBT switching tube Q1, the armature winding N1 of transformer and IGBT switching tube Q2.In Circuit Fault on Secondary Transformer, described secondary windings N2 and described secondary windings N3 obtains voltage by magnetic core of transformer coupling, when pwm pulse closes driving simultaneously, IGBT switching tube Q1 and IGBT switching tube Q2 closes simultaneously, and the electric energy that the armature winding N1 of transformer primary side continues needs to be discharged by sustained diode 2, sustained diode 1.
Under electric welding machine is operated in MMA or TIG function, relay K 1 must not be electric, and switch portion disconnects, and secondary windings N3 is disconnected and does not form loop; When pwm pulse is opened, the electric energy that secondary windings N2 is coupled needs to be transported to output plus terminal by commutation diode D3, i.e. OUT+ end, exports weld load export negative terminal by winding N5, i.e. A_OUT-end, thus forms welding circuit; When pwm pulse is closed, commutation diode D3 ends, and the electric energy that winding N5 stores forms continuous current circuit by sustained diode 4 and weld load.In said process under MMA or TIG function circuit can regard as electric energy from armature winding N1 be coupled to secondary windings N2 again through commutation diode D3 rectification, sustained diode 4, winding N5, output plus terminal and weld load export negative terminal and weld load forms complete welding circuit.This process does not have relay to participate in completely, and circuit is simple, output current size only depend on parallel diode number.
Under electric welding machine is operated in Plasma Air low-temperature plasma function, relay K 1 obtains electric, secondary windings N3 winding is switched on and forms loop, when pwm pulse is opened, the electric energy that secondary side secondary windings N3 is coupled needs to be given to output plus terminal (OUT+) by commutation diode D5 rectification, and exports negative terminal (i.e. C_OUT-end) and the welding circuit of winding N6 formation by broaching load; When pwm pulse is closed, commutation diode D5 ends, and the electric energy that winding N6 and inductance L 1 winding store forms continuous current circuit by sustained diode 6 and weld load.In said process under Plasma Air low-temperature plasma function circuit can regard as electric energy from armature winding N1 be coupled to secondary windings N3 again through commutation diode D5 rectification, sustained diode 6, winding N4 afterflow supply output plus terminal and broaching load export negative terminal, and then and broaching load form complete cutting loop.
Though this process has relay K 1 to participate in, but under relay just works in cutting function, due to the characteristic that Plasma Air low-temperature plasma fuction output electric current little output loading voltage is high, a specified 40A relay just can meet the demands, and reduces circuit cost, volume and fault rate.Although this process secondary windings N2 is also in work, only with OUT+ and C_OUT-output port under Plasma Air low-temperature plasma function, so N2 winding loop only has voltage but do not have output current to produce, do not affect cutting current.High-frequency arc strike inductance cleverly by secondary use two groups of windings separately; under TIG function, use secondary windings N2 welding circuit, during high-frequency arc strike, hf and hv pulse makes A_OUT-output port produce high-voltage breakdown welding protection gas argon gas formation ionization by winding N4 uncoupling winding N5 and forms welding circuit with OUT+.Under Plasma function, use secondary windings N3 welding circuit, during high-frequency arc strike, hf and hv pulse makes C_OUT-output port produce high-voltage breakdown welding protection gas air formation ionization by winding N4 uncoupling winding N6 and forms cutting loop with OUT+.In sum, because two output loops independently separate, be independent of each other and disturb, what the output current of MMA and TIG was done is larger, and the cost of whole circuit significantly reduces, the longer service life of machine.
Above specific embodiments of the invention are described.It is to be appreciated that the present invention is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present invention.
