Title: Fourth-generation inverters add artificial intelligence to the control of GMA welding

A new level of control has been achieved over the welding arc by using some of the latest techniques in artificial machine-intelligence computer control and by direct control of the short-circuit waveform. By controlling the short-circuit waveform in real time, these artificially intelligent power supplies control the instantaneous welding conditions and improve the GMAW process in terms of welding performance. These artificial-intelligent power supplies can yield many benefits. Among them are lower spatter levels, both in argon-based shielding gases and 100% CO[sub 2] shielding gases. Another benefit is faster arc speeds. In many cases the arc speeds can be 25% faster. Better productivity, through the better arc-striking capability and reduction of downtime associated with spatter on peripheral equipment, is another important factor. These power supplies are synergic and therefore provide for easier operator control. In addition, they have higher electrical efficiency; thus they yield lower operating cost.
