Abstract

PURPOSE:To eliminate the unstability of welding work in a short circuit transfer arc welding machine by comparing the detected value of the voltage between a wire and base metals with the prescribed voltage, and controlling the electric charge quantity in the arc discharge period in accordance with the compared value thereby controlling the voltage so as to attain the prescribed value. CONSTITUTION:In a short circuit transfer arc welding mchine which performs welding by repeating short circuit and arc discharge between wire electrode 7 and base metals 10, the electric charge quantity of the current flowing in the arc period is changed over according to the feed rate (v) of the wire 7, and the electric charge quantity of the current is so corrected that an average welding voltage V attains the prset reference average value. In spite of vertical oscillating of a torch 9, the welding is accomplished always in the costant short circuit periods and therefore the influence of hand shaking, etc., is eliminated. In this way, the wire 7 is fed to the torch 9 by a feed motor 8, the leading end of the molten wire electrode 7a is short-circuited to the base metals 10, and the current is supplied until the next regeneration of the arc, whereby the transfer of the molten wire electrode to the base metals 10 is accomplished stably.
