This invention discloses an automatic start-up and load-variable control method for an air separation argon purification system. Automatic start-up, load-variable operation, and steady-state adjustment of the argon purification system no longer require operator intervention; operators only need to change the system's load flow rate setpoint. During automatic start-up, load-variable operation, and steady-state adjustment, the system operates stably, and the nitrogen content of the liquid argon in the product meets requirements. This completely solves the problems of easy overpressure in the argon purification tower and the necessity of discharging substandard liquid argon during the initial automatic operation of the argon purification system, eliminating safety hazards and saving energy consumption. When the argon purification system is operated at reduced load, the minimum load can reach 20% of the normal load, and the operating conditions remain stable, while the product quality still meets requirements. This solves the problem of frequent start-up and shutdown of the argon purification system when user usage fluctuates significantly.
