Variable balance AC squarewave technology can reduce filler metal, flux, labor time, and heat input.

Variable balance AC squarewave submerged arc welding (SAW) technology, from Miller Electric Mfg. Co., overcomes the traditional problems or limitations of saw with all other processes, including Dc electrode positive (DCEP), DC electrode negative (DCEN) and traditional AC.

For example, on groove welds on 1.25 in. thick steel plate, variable balance AC squarewave SAW increases the deposition rate up to 59 percent over DCEP using the same welding parameters and wire types. Thus fabricators can replace old technology and immediately lower weld costs without ...
