The invention discloses an argon arc welding lift-igniting control circuit for suppressing short-circuit arc current. The control circuit comprises a main circuit work control circuit, a current-specified circuit and a current feedback circuit; a short-circuit arc judging circuit is used to judge whether a circuit to a welding gun and a workpiece is shorted, and output low level to release a main control chip start-stop control pin, so that a main control chip starts to work; if an electric welding machine is inoperative for a long time, the short-circuit arc judging circuit outputs high level to lock the main control chip start-stop control pin, so that the main control chip works in the standby mode; the current-specified circuit is used to detect that a potentiometer set by a user outputs voltage to a proportional-integral operation circuit proportionally; the current feedback circuit is used to detect that a main circuit transformer of the electric welding machine outputs the voltage to the proportional-integral operation circuit proportionally. In the invention, the short-circuit arc current can be suppressed to avoid electric spark caused by the short-circuit arc, and the weld quality is improved.
