PROBLEM TO BE SOLVED: To provide a drawing method of pail pack welding wire, which can feed the welding wire so as to form an accurate welding bead without causing snaking of the bead and does not cause entangling or twisting of the welding wire in the pail pack. SOLUTION: In the wire drawing method of the pail pack welding wire for welding, 2 sets of 3 roller devices are connectedly located above a pail pack drawing exit. The axial directions of these sets of devices are shifted by 90°each other and the welding wire is drawn out while being plastically deformed in a circular shape with a diameter of 300-1,500 mm.
