2 DESCRIPTION OF THE SYSTEM

2.1 Introduction

KINGSTAR 400 TS and KINGSTAR 520 TS are multiprocess systems designed for
synergic MIG/ MAG, conventional MIG/MAG, TIG-DC with arc striking by contact and
MMA welding, carried out using inverter technology.
Each system consists of an electronic power source, a wire feed unit and a series of
accessories for adapting to different uses (see list in the Sales Catalogue).
Interfacing with the operator is via two control panels, one touch panel on the power
source and one simplified panel located on the wire feed unit.

2.2 Technical specifications

To verify the technical specifications, see the machine plate, Instruction Manual, and
Sales Catalogue.

2.3 Power source description KINGSTAR400TS, KINGSTAR 520TS

Each system component, power source, wire feed unit and control panel contains a
microprocessor circuit that communicates with the other microprocessors via a CAN-
BUS serial line as well as managing functions for its own group in order to cooperate
actively and continuously with system operation.
The following units can be identified based on this architecture:
MASTER microprocessor, in power source control board (70);
INVERTER CONTROL microprocessor, in power source control board (37);
MOTOR microprocessor, in wire feed unit motor control board (222);
PANEL microprocessor in panel board (212).
Each microprocessor is programmed with a different program, which must be
compatible with that of the other microprocessors. For more streamlined program input
and updating, a system is included that allows all for microprocessors to be
programmed in a single programming session.
KINGSTAR400TS and 520TS units are direct voltage, current-controlled power
sources consisting of a three phase bridge rectifier, a DC/AC converter (inverter), and
an additional bridge rectifier.
Refer to the wiring diagram in section 5, the block diagram in fig. 2.3.1, the exploded
view drawings and the tables in section 4 to identify the main blocks making up the
power source.
Main switch (5) powers mains filter board (39). It contains the filter for reducing
conductive interference on the mains network.
Bridge rectifier (23) and power board (48) are the power elements of the first two
converter stages. More specifically, fig. 2.3.1 identifies:
- three-phase bridge rectifier (23), which converts the alternating mains voltage
(400 Vac) to direct voltage (540 Vdc) for powering the DC capacitors and the
inverter;
on power board (48):
- DC capacitors, for reducing the equivalent impedance viewed in the direction of
the mains from the next inverter;
