[0007] Further, the first pipeline is provided with a first on-off valve, which is located between the first one-way valve and the first output joint.

[0008] In this way, the first on-off valve is located inside the shell, which reduces the flow distance of CO2 and argon, reduces the amount of CO2 and argon remaining in the first pipeline, avoids the influence of a large amount of CO2 on argon arc welding or a large amount of argon on gas shielded welding, and the first on-off valve can be controlled conveniently by using a solenoid valve.

[0009] Further, the second pipeline is provided with a second on-off valve, which is located between the first one-way valve and the second output joint.

[0010] In this way, the second on-off valve is located inside the shell, which reduces the flow distance of air and argon, reduces the amount of air and argon remaining in the second pipeline, avoids the influence of a large amount of air on argon arc welding or a large amount of argon on a cutting machine, and the second on-off valve can be controlled conveniently by using a solenoid valve.

[0011] Further, the second pipeline is provided with a second one-way valve at a position between the first one-way valve and the second input joint, and the delivery direction of the second one-way valve is arranged towards the second output joint.

[0013] Further, the shell is provided with a third output joint.

[0014] In this way, the third output joint can be connected to a circuit board connected to a manual welding device, so that the electric welding machine has the function of manual welding, and has four functions at the same time, which is more practical.

[0015] Further, the wire feeding assembly comprises a wire feeder and a wire reel shaft, and the wire feeder is connected to the first output joint.

[0016] In this way, the wire reel shaft can be wound with a large amount of welding wire, so that the wire feeder can pull out the welding wire on the wire reel shaft and feed it into the first output joint, and the structure is simple.

[0017] Further, it further comprises a partition plate, which is located in the shell, and the circuit board and the wire feeding assembly are located on two sides of the partition plate, respectively.

[0018] Thus, the partition plate can separate the circuit board and the wire feeding mechanism, avoid interference of various connecting lines of the circuit board on the wire feeding process, be more stable, and only one plate can complete installation of the internal structure, so that the cost is lower and the internal structure is more direct and convenient to disassemble and assemble.

[0019] Further, the first pipeline and the second pipeline are located on the same side of the partition plate as the circuit board.

[0020] Thus, the two pipelines can be avoided to affect the wire feeding process, and be more stable.

[0021] Further, an insulating plate is arranged between the partition plate and the circuit board.

[0022] Thus, the partition plate can be made of metal material, which is more stable, and the insulating plate can avoid influence of the metal partition plate on the circuit board, and reduce influence of vibration generated in the wire feeding process on the circuit board, and be more stable.
