Mastertig 2000 AC/DC Z002
The primary rectifier VG102 rectifies the net voltage. The primary choke L001 and smoothing
capacitors CZ213...CZ216 filter the DC voltage. Working capacitors CZ201...CZ212, main
transformer T001 and IGBT-transistor VG101 form the primary inverter. Primary circuit current
is measured by current transformer T004.
Mastertig 2500 AC/DC Z001
The primary rectifier VG101 rectifies the net voltage. Primary choke L001 and smoothing
capacitor C003 filter the DC voltage. Primary inverter´s working capacitors are mounted onto
the main circuit card Z001.
