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 rst time. Additional information on Kemppi products and

their use can be obtained from Kemppi or a Kemppi dealer.

The specications and designs presented in this manual are subject to

change without prior notice.

NOTE! Items in the manual that require particular attention in order to minimise

damage and personal harm are indicated with this symbol. Read these sections

carefully and follow their instructions.

1.2 SAFETY INSTRUCTIONS

Kemppi welding devices conform to international safety standards. Safety

is an important issue in equipment design and manufacturing. Therefore,

Kemppi welding solutions are unparalleled in safety. There are, however,

always certain hazards involved in using welding equipment. Therefore, to

ensure your personal safety and the safety of your working environment,

carefully read the safety instructions below and respect them.

Use of personal protective equipment

• Thearcanditsreectingradiationdamageunprotectedeyes.Shield

your eyes and face appropriately before you start welding or observe

welding. Also note the dierent requirements for the darkness of the

screen in the mask as the welding current changes.

• Thearcradiationandspattersburnunprotectedskin.Alwayswear

protective gloves, clothing and footwear when welding.

• Alwayswearhearingprotectioniftheambientnoiselevelexceedsthe

allowable limit (e.g., 85 dB(A)).

General operating safety

• Exercisecautionwhenhandlingpartsheatedinwelding.Forexample,

the tip of the welding torch, the end of the welding rod and the work

piece will heat during gouging to a burning temperature.

• Neverwearthedeviceontheshoulderduringweldingandnever

suspend it by the carrying strap during welding.

• Donotexposethemachinetohightemperatures,asheatmaycause

damage to the machine.

• Keepthetorchcableandearthingcableasclosetoeachotheras

possible throughout their length. Straighten any loops in the cables. This

minimisesyourexposuretoharmfulmagneticelds,whichmayinterfere

withapacemaker,forexample.

• Donotwrapthecablesaroundthebody.

• Inenvironmentsclassiedasdangerous,onlyuseS-markedwelding

devices with a safe idle voltage level. These work environments include,

forexample,humid,hotorsmallspaceswheretheusermaybedirectly

1.3 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 dierent mains voltages: 230 V (Minarc

150) and 110 V (Minarc 151).

MInarc 150VRD is equipped with so called Voltage Reduction Device (VRD)

function. VRD maintains open circuit voltage under 35 V.

Minarc 150AU and 120AU for mains voltages 240 V and with VRD function are

onmarketonlyforAustraliaandNewSealand.

Minarctoleratesagreatuctuation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.
