Magnetic induction manual arc welding simulation training device

The invention discloses a magnetic induction manual arc welding simulation training device which comprises a simulation welding workpiece set, a simulation welding rod set and a simulation welding machine. An ultrasonic ranging sensor arranged on one end of a magnetic stripe installation box is connected with a power supply socket through a power supply wire arranged at the bottom of the magneticstripe installation box. A pneumatic triple body, a two-position three-way manual valve, a two-position five-way solenoid valve and a single-rod double-acting cylinder are sequentially connected. A one-way throttle is connected between the two-position five-way solenoid valve and the single-rod double-acting cylinder. A power supply switch and a conversion power supply are connected. The power supply socket is connected with the conversion power supply. A magnetic inductor A, a magnetic inductor B, a magnetic inductor C, a buzzer and an LED lamp bead are connected with the conversion power supply in series. The input
