1.2. PRODUCT PRESENTATION
Kemppi Minarc is a manual metal arc welding machine, small in size, suitable for
industry, site and repair welding. The unit uses a one phase connection voltage and it is
manufactured in two different welding power sizes 110 A and 140 A.
Minarc tolerates a great fl uctuation of input voltage and there-fore 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 4.2. Ordering
numbers.
1.3. SAFETY PRECAUTIONS
Read the warning texts carefully and follow the instructions.
Arc and welding spatter
Arc and the refl ected 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 fi re and explosion
Observe the fi re safety instructions. Remove fl ammable material near the place where
you will weld. Have necessary fi re extinguishing equipment at hand when you weld.
Note dangers caused by special jobs, such as risk of fi re and explosion when welding
tanks. Note! Sparks may ignite fi re even hours later!
Welding is working with fi re, note special instructions for such work.

Mains voltage
Never take welding machine inside the piece you are working on (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 fi re. 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 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.
2. BEFORE YOU START USING THE UNIT
2.1. UNPACKING
