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.

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.
