PROBLEM TO BE SOLVED: To provide a control method for three electrode arc welding for conducting welding by generating three arcs from one welding torch between three welding wires electrically insulated from one another and an article to be welded 2. SOLUTION: In the control method for three electrode arc welding for conducting welding by feeding three wires from one welding torch 4 insulated from one another, three wires are arranged in series on the welding line, a lump formed between a front travel wire 1A and a rear travel wire 1B by the arc force of the rear travel wire 1B is suppressed by the arc force of an intermediate wire 1C.
