TV01 HF coil. When replacing the coil it is important that the winding is
correctly connected. The connection is polarity sensitive.
Input voltage: about 550V; Output voltage: about 9kV.
V01, V02 Mains rectifiers for DT E 200.
Warning: Do not mix up wires 007 and 090, when connecting them to the
rectifiers. Wire 007 must be connect ed to the positive (+) pole of V02.
V05 Diode, used with C09 and R3 to limit the voltage between plus and minus
on the IGBTs (Q01 -- Q04). Only for DTE 255.
V07 Diode module. When measured with a diode tester the forward voltage
drop is about 0.2 -- 0.3V.
When replacing the diode module, follow the fitting instructions for the
IGBTs on page 62.
X The pin connectors on the circuit boards are marked with XA, XB and so
on. This is repeated on each circuit board. The connectors on circuit board
AP04 are marked X1, X2 and so on.
XP Pin connectors.
XS Sleeve connectors.
XS12 Central connector for TIG. OKC connector for TIG on machines without
central connector.
XS13 OKC connector for MMA
XS14 OKC connector for return welding current cable.
XS15 Connection for TIG start. Only machines with OKC connector for TIG.
XT Terminal block.
YV01 Solenoid valve.
Introduction to the wiring diagram
Some of the circuit boards are divided into function blocks which are described in the
descriptions of operation. The blocks are listed in the list of contents.
