Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1: a kind of expeling welding wire of carbon dioxide gas shielded welding machine melts ball circuit, comprise: resistance R1, a termination power VCC of resistance R1, the anode of another terminating diode D1, the negative electrode of diode D1 connects one end of arc welding gun switch Ts, the other end ground connection of arc welding gun switch Ts;
One end of the anode connecting resistance R2 of diode D1, the base stage of one end of other end connecting resistance R3 of resistance R2, the negative electrode of diode D2 and NPN transistor T1; The grounded emitter of the other end of resistance R3, the anode of diode D2 and NPN transistor T1; The colelctor electrode of NPN transistor T1 connects the anode of voltage-stabiliser tube ZD1 by resistance R4;
A fixing termination power VCC of adjustable resistance VR2, a stiff end of another fixing termination adjustable resistance VR1, any one is connected with two stiff ends in the adjustable side of adjustable resistance VR2; A stiff end of another fixing termination adjustable resistance VR3 of adjustable resistance VR1, another stiff end ground connection of adjustable resistance VR3, any one is connected with two stiff ends in the adjustable side of adjustable resistance VR3; The negative electrode of voltage-stabiliser tube ZD1 connect adjustable resistance VR1 adjustable side and as the output driving away welding wire and melt ball circuit.
Drive away welding wire and melt ball circuit for exporting weldingvoltage control instruction V01.
After pressing arc welding gun switch button Ts, diode D1 conducting → transistor T1 cut-off → weldingvoltage control instruction is by VR1 regulation output, and at this moment export normal weld voltage instruction, this normal weld voltage instruction is a higher level.At the end of welding, decontrol arc welding gun switch Ts, power supply VCC is through R1, R2 and R3 bias voltage, and transistor T1 conducting → voltage-stabiliser tube ZD1 punctures conducting, and the weldingvoltage control instruction that now negative electrode of voltage-stabiliser tube ZD1 exports changes a more low level expeling welding wire into and melts ball voltage instruction.Puncture conducting due to voltage-stabiliser tube ZD1, output voltage instruction is limited in ZD1 breakdown voltage, makes expeling welding wire melt the level of level lower than normal weld voltage instruction of ball voltage instruction.Thus at the end of welding, melt ball voltage instruction by expeling welding wire and make the drive circuit of welding machine (not drawing in Fig. 1) output voltage lower than normal weld voltage, welding wire melts ball and diminishes, and reaches and drives away the object that wire tip melts ball.Its action sequence is shown in Fig. 2.
Utilize and drive away welding wire and melt ball circuit, can be implemented in after welding terminates, suitably reduce welding machine output voltage, make wire tip melt ball and diminish, when being convenient to welding next time, striking is easy.
