READ THIS FIRST

Maintenance and repair work must be performed by an experienced person, and electrical

work only by a trained electrician. Use only recommended replacement parts.

This service manual is intended for use by technicians with electrical/electronic training for

help in connection with fault-tracing and repair.

Use the wiring diagram as a form of index for the description of operation. The circuit boards

are divided into numbered blocks, which are described individually in more detail in the

description of operation. Component names in the wiring diagram are listed in the

component description.

Use the spare parts list as a guide to where the components are located in the equipment.

The spare parts list is published as a separate document, see the "SPARE PARTS AND

ACCESSORIES" chapter in this manual.

This manual contains details of design changes that have been made up to and including

January 2020.

INTRODUCTION

The "ES 150i", "ES 180i", "ES 180i Pro" and "ES 200i Pro" are an inverter-based power

sources intended for MMA (Manual Metal Arc) and TIG (Tungsten Inert Gas) welding.

The "ET 180i", "ET 200iP" and "ET 200iP Pro" are an inverter-based power sources

intended for MMA (Manual Metal Arc), TIG (Tungsten Inert Gas) welding and HF TIG (High

Frequency Tungsten Inert Gas) welding.

Design structure of the power source

The "ES 150i", "ES 180i", "ES 180i Pro", "ES 200i Pro", "ET 180i", "ET 200iP" and

"ET200iPPro" power sources are transistor-controlled, operating on the inverter principle. It

consists of a number of function modules. Each module has a module number, which is

always included as the first part of the name/identification of components in the module. The

modules have the following main functions:

The modules have the following main functions:

Setting panel module

The main function is for the user to define welding process settings.

Input module

The main function is to convert power mains input voltage to stable voltage free from

conducted disturbances as required by the EMC directive.

TIG module (valid for ET 180iP, ET 200iP Pro)

The main function of the TIG module is to produce high voltage, high frequency pulses, thus

enabling non-contact ignition of the electric welding arc.

Primary module

The main function is a full bridge inverter operating at a switching frequency of 97kHz. IGBT

transistors are used as switching elements.

Transformer module

The main function is to transform high voltage / low current to high current / low voltage.

Output inductor module

The main function is to supply the welding current. The module contains an inductor and a

current sensor.

Control module

This is the master of the system. The module handles the system status. It is a hub for

events/errors occurring in the system, and it collects meta-data on other boards in the

system.

Secondary module

The main function is to supply the welding current. This module contains an additional board

for increasing the output voltage at low currents, to enable higher welding performance for

cellulosic electrodes.

To avoid equipment breakdown, the power source

measures the mains voltage when the power switch is

turned ON. To protect the power source, check that the

mains voltage is correct according to the rating (230 VAC)

before switching on the PFC.

RECTIFY AND FILTER Transfer the power from AC into DC.
