1. PREFACE

1.1. INTRODUCTION

Congratulations on having purchased a KEMPPI product. Properly installed and used KEMPPI products should prove to be productive machines requiring only a small amount of regular maintenance.

This manual is arranged to give you a good understanding of the equipment and its safe use. There is also information on both servicing the unit as well as its technical data. Read the instructions before taking the machine into use or servicing it for the ﬁrst time. Additional information on Kemppi products and their use can be obtained from Kemppi or a Kemppi dealer.

The speciﬁcations and designs presented in this manual are subject to change without prior notice.

In this document, for danger to life or injury the following symbol is used: Read the warnings carefully and follow the instructions. Please also study the operation safety

instructions and respect them when installing, operating and servicing the machine.

1.2. PRODUCT INTRODUCTION

Kemppi Minarc is a manual metal arc welding machine, small in size, suitable for industry, site and repair welding. The unit uses one phase connection voltage and it is manufactured for two different mains voltages: 230 V (Minarc 150) and 110 V (Minarc 151).

Minarc tolerates a great ﬂuctuation of input voltage and is thus suitable for work on sites using generator as well as to be used with long power cables. Inverter technology has been used when designing the unit. Power regulation in power source is done with IGBT transistors. Welding and earth cables are supplied with the unit. They are equipped with suitable connections for the unit electrode holder, earth clamps and connections.

Minarc can also be used for TIG welding. TIG arc is started by scratching. Ordering numbers of additional equipment for TIG welding can be found in chapter 5. Ordering numbers.

1.3. OPERATION SAFETY

Read the warning texts carefully and follow the instructions.

Arc and welding spatter

Arc and the reﬂected radiation from it can damage unprotected eyes. Shield your eyes and protect your surroundings appropriately before you start welding. Arc and welding spatter will burn unprotected skin. When welding, use protective gloves and clothing.

Danger of ﬁre and explosion

Observe the ﬁre safety instructions. Remove ﬂammable material around the place where you will weld. Have necessary ﬁre extinguishing equipment at hand when you weld. Note dangers caused by special jobs, such as risk of ﬁre and explosion when welding tanks. Note! Sparks may ignite ﬁre even hours later!

Welding is working with ﬁre, note special instructions for such work.

Mains voltage

Never take welding machine inside the work piece (e.g. container or car). Never set the welding machine on wet surface. Replace faulty cables immediately, they create a danger to life and can cause a ﬁre. See that the connecting cable does not stick nor touch sharp edges or a hot welding piece.

Welding current circuit

Isolate yourself from the welding current circuit by wearing dry and undamaged protective clothing. Never work on a wet surface. Never use damaged welding cables. Never set neither electrode holder, earth clamp nor the welding cables on top of the power source or other electric equipment.

Welding fumes

Ensure adequate ventilation. Always take special measures when welding metals containing lead, cadmium, zinc, mercury or beryllium.

This equipment’s electromagnetic compatibility (EMC) is designed for use in an industrial environment. Class A equipment is not intended for use in residential location where the electrical power is provided by the public low-voltage supply system.

2. BEFORE YOU START USING THE UNIT

2.1. UNPACKING

The equipment is packed in durable packages, designed specially for them. Nevertheless, always before using the equipment, make sure it was not damaged during transportation. Also check that you have received what you ordered and that there are instructions for it. NOTE! The packaging material of the products is suitable for recycling.

2.2. PLACING THE UNIT

Place the unit on horizontal, solid and clean surface. Shield it from heavy rain and scorching sun. Make sure that cooling air circulates freely.

2.3. SERIAL NUMBER

Serial number of the unit is marked on the rating plate of the unit. The serial number makes it possible to trace product manufacturing series. You might need the serial number when placing spare parts orders or when planning maintenance.

2.4. MAIN COMPONENTS

Connect welding cable and earth cable to their connections on the power source. Mains cable and wall plug are already installed. (Note! Minarc 151 (110 V) is delivered without a plug).
