Protective device for argon arc welding machine

The invention belongs to the technical field of welding equipment, and particularly relates to an argon arc welding machine protection device which comprises a protection plate. A welding machine main body is mounted outside the protection plate; a pipe joint is mounted outside the welding machine main body, and the pipe joint penetrates through the protection plate; the protection plate is installed outside the welding machine body to form protection, the situation that foreign objects collide with the welding machine body is reduced, a first clamping ring and a second clamping ring are matched to straighten the easily-broken position of the first air pipe, a guide arc plate guides the outside of the first air pipe, and the probability of occurrence of potential safety hazards such as air leakage caused by serious bending of the first air pipe is reduced; the first monitoring ring is used for monitoring the easily-broken position of the first air pipe in real time, the first monitoring ring gives an alarm wh
