Summit Arc 1000 is a three-phase squarewave AC machine with phase-shifting capability and optional plugs to refine arc for specific needs. Miller Electric first introduced Variable Balance Alternating Current (VBAC) for submerged arc welding (SAW) in 1997 when it introduced the Summit Arc 1000 at the AWS weld show. This was the first power source to use a three phase primary input to generate an AC output. This was traditionally and still most commonly done with a single phase power source. The Summit Arc has since been recognized worldwide for its ability to increase deposition rate over that of DCEP, decrease heat input at given amperages and still providing sound quality welds. Power source is capable of VBAC, DCEP, DCEN and CC/CV. Three-phase primary power input reduces primary input amperage, input fuse size and input primary cable. Fan-On-Demand cooling system only works when needed reducing energy usage and noise. In Multiple-torch SAW operations, Phase-Shift Technology allows the Summit Arc to guarantee arc stability, by enabling the welding machines an ability to communicate and coordinate sine wave polarities and phase delays.
