1. GENERAL

These instructions describe the use of Kemppi's Master M 205 and 323 welding machines designed for light- to medium-

duty professional use in MIG/MAG welding.

Master M 205 and 323 welding machines include both manual and automatic welding processes. Pulse welding is pos-

sible with the Master M 205 machine (220...240 V).

Master M is designed to be used together with Kemppi's Flexlite GX MIG welding guns with euro connector.

Master M can be used also for TIG * and MMA ** welding.

* TIG welding requires the use of a dedicated Flexlite TX TIG torch with euro connector.

** MMAwelding requires a dedicated DIX-euro adapter.

Important notes

2. INSTALLATION

Do not connect the equipment to the mains before the installation is complete.

Do not modify the welding equipment in any way, except for the changes and adjustments covered in the man-

ufacturer’s instructions.

Place the machine on a horizontal, stable and clean ground. Protect the machine from rain and direct sunshine.

Check that there is enough space for cooling air circulation in the machine vicinity.

Before installation

•Make sure to acknowledge and follow the local and national requirements regarding installation and use of high

voltage units.

•Check the contents of the packages and make sure the parts are not damaged.

•Before you install the power source on site, see the requirements for the mains cable type and fuse rating.

Distribution network

This Class A equipment is not intended for use in residential locations where the electrical power is provided by the

public low-voltage supply system. There can be potential difficulties in ensuring electromagnetic compatibility in

those locations, due to conducted as well as radiated radio-frequency disturbances.

Master M 323: Provided that the short circuit power of public low voltage system at the point of common coupling is

higher than 1.6 MVA, this equipment is compliant with IEC 61000-3-11:2017 and IEC 61000-3-12:2011 and can be

connected to public low voltage systems. It is the responsibility of the installer or user of the equipment to ensure, by

consultation with the distribution network operator if necessary, that the system impedance complies with the

impedance restrictions.

2.1 Installing power source mains plug

Only an authorized electrician is allowed to install the mains cable and plug.

Do not connect the machine to the mains before the installation is complete.

Install the mains plug according to the Master M device and site requirements. Refer also to "Technical data" on page63

for device specific technical information.

The mains cable includes the following wires:

1. Brown: L1

2. Black: L2

3. Grey: L3

4. Yellow-green: Protective earth

Cable type and fuse rating requirements:

Unit amperage Cable type Fuse rating

200 A (220-230 / 110-130 V) 2.5 mm216 / 16 A

320 A (380-460 / 220-230 V) 2.5 mm216 / 32 A
