摘要： In a consumable electrode type arc welding method, when short circuit shift welding is conducted at the start of an arc in the process of pulse arc welding and also when an inclinations of a rise or fall is decreased in the case of starting an arc in the process of pulse welding and also when an inclination of a short circuit current is increased, short circuit, which irregularly occurs at the start of an arc, can be released in a short period of time and the arc can be stabilized early. When the generation of a magnetic arc blow is suppressed, it becomes possible to form proper welding beads. Due to the foregoing, the efficiency of welding work can be enhanced.

摘要： A power apparatus is used in an arc welding device to control a weld operation during a welding start time. An improved arc start performance is obtained in both a cooled condition of the welding wire tip end portion and a red heated condition thereof. A feed quantity of the consumption electrode during the weld start time is changed depending on whether the welding wire tip end portion is cooled or red heated from a prior arc welding operation.

摘要： A welding condition inputting equipment capable of setting the welding conditions such as welding current and welding voltage easily and securely is disclosed. The welding condition inputting equipment comprises an operating section for inputting the welding conditions, a determining section for selecting items, and a display section for displaying selected items. When the welding conditions are input, the operating section outputs the conditions to the determining section. When the conditions are input in the determining section, the determining section selects items relating to welding corresponding to the conditions, and outputs the items to the display section. When the items are input in the display section, the display section displays the items. The operating section specifically includes a dial, a switch, and a push-in dial switch integrally combining a dial rotation detecting part.

摘要： When a welding voltage is lowered, a pulse period is shortened or a peak current is reduced so that an average of a pulse frequency is not changed. Therefore, short circuit is regularly generated and a quantity of generated spatter is reduced. When the welding voltage is changed immediately before a melting drop separates from a tip of a wire, separation of the melting drop is predicted and the pulse period is ended. Due to the foregoing, a melting drop is regularly shifted at each pulse, and a quantity of generated spatter is reduced.
