PURPOSE:To provide the titled extremely simple and easy equipment only with this welding conditions as the parameter to be inputted and indicated in advance by making with constituting so as to select and set automatically the crater treating conditions of the welding completion time from the indicated welding conditions. CONSTITUTION:A welding current Ia1, welding voltage Va1, welding speed v1 are inputted to a controlling device 6 for instruction as this welding conditions shown in (a). In the device 6, then, the data basis is retrieved as per (c) from the combination of the current Ia1 and the speed v1 as shown in (b), the crater treating conditions, i.e., the crater current Ic, crater voltage Vc, crater time tc are selected and all the necessary parameters are completed as shown in (d) the same as before, and the welding is performed by the welding executing part 10. Consequently only with instructing this welding conditions everything can be done automatically upto the crater disposal and the input instruction of the conditions is simplified very much and a good welding result is obtainable at all times. |
