Abstract
A pulse arc welding machine including a wire electrode, a wire feeding unit for feeding the wire electrode to a base material, a base current source for supplying a base current between the wire electrode and the base material, a pulse current source for supplying a pulse current superposed on the base current, a detector for detecting the arc discharge voltage between the wire electrode and the base material, and a controller. The controller compares a detected output value from the detector with a preset reference value to thereby control the amount of heat applied to the wire electrode wherein the arc voltage between the wire electrode and the base material is maintained substantially at a value determined by the reference value.
