METHOD AND DEVICE FOR POWER CONVERSION, AND WELDING SET

摘要

FIELD: process engineering.SUBSTANCE: invention relates to control over welding set 1 and to welding set. Proposed welding set comprises electrochemical storage 2, torch 7 for arcing 6 connected with device 4 of control over I/O device 5 for adjustment of welding current and power section for conversion of electrochemical storage power. Said control device 4 computes estimated magnitude of residuary welding time for arcing 6 depending of the capacity of said electrochemical storage 2 and steady-state welding current. Besides it comprises display 27 to indicate computed residuary welding time.EFFECT: control device 4 corrects residuary welding time proceeding from actual welding current magnitudes.13 cl, 5 dwg
