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
