PROBLEM TO BE SOLVED: To provide a method for remote-controlling or managing an arc-welding shop adopting a plurality of welding torches. SOLUTION: The plurality of welding torches (10) supplied together with respective wires (11) which shift at the wire velocity (V) and are consumed while receiving the current having the intensity (I), are used. Then, the wire velocity value (V) feeding each welding torch in a prescribed period (T) to each wire (11) is decided with a velocity sensor, or the current intensity value (I) showing the average power received in the prescribed period (T) to each wire (11) is decided with a current sensor. Then, the method decides a duty factor (DF) and a deposit ratio (DR) for each welding torch (10) in the shop, and additionally, a productivity parameter selected from an average value of these parameters for whole welding torches in the shop, obtains the method decided from each velocity value (V) of the wire (11) or each intensity value (I) of the current obtained with the above, and the system combining this method is obtained.
