Detailed Description
Three-phase DC projection welder It is a new type of machine,where Secondary Current is rectified on the output Of the Three-phase transformer main features: Direct Current in the secondary loop minimizes inductance losses vs.those of single phase AC machines. Direct Current,is more efficient than AC current where current changes its value within a cycle ftom 0 to max Amplitude As a result,DC machine can provide steady heat input into welded material,minimizing,sparks,achieving better Penetration in multi-layer weldments. Balanced Three-phase input improves load on the primary power system and improves power factor. Direct current makes it possible to weld aluminum and aluminum alloys.
