    摘要： In an arc welding control method of repeating a short circuit and an arc to perform welding, control is carried out to conduct a welding current having a first polarity for a short circuit period, and a first commutation to commutate the welding current from the first polarity to be a polarity of the welding current for the short circuit period to a second polarity to be opposite to the first polarity is carried out for an arc period subsequent to the short circuit period. Furthermore, control is performed to carry out a second commutation to commutate the welding current from the second polarity to the first polarity for the arc period in which the first commutation is executed. Consequently, it is possible to reduce an energy input amount to a base metal, thereby suppressing burn-through in welding of a thin plate.

    摘要： A method to determine welding conditions includes relational expressions or tables about various parameters for setting welding conditions. The method can determine and display the recommended values for the welding conditions which are suitable for the information about the object to be welded and the information about the welding method set by the operator. The welding conditions include a welding current, a welding voltage, a wire feed speed, a welding speed, and a leg length. Furthermore, if the operator changes the recommended value for a welding condition to a new value, the method can determine new recommended values for the other welding conditions compatible with the new value and display the new recommended values.

    摘要： A welding control unit has a common power section for detecting contact of a welding material and for welding. A material contact detector for detecting contact of the welding material and a workpiece, and a power controller are built in the welding control unit. This stabilizes a bead shape in starting welding. The number of components can also be reduced, resulting in more inexpensive equipment. In addition, only a space for installing the welding control unit is needed without any additional space.

    摘要： An AC pulse arc welding method of the present invention sets an appropriate AC frequency based on a wire feed rate and a polarity ratio when the polarity ratio is changed without changing the wire feed rate to control a heat input to a base material, and sets an appropriate straight polarity current value necessary for one drop per pulse from the polarity ratio and the AC frequency in AC pulse welding. The method makes it possible to achieve appropriate AC pulse welding by setting the polarity ratio, and to easily set the welding conditions.
