1. INTRODUCTION
Congratulations on purchasing the Kemppi MinarcTig
TM
180 TIG/MMA machine.
MinarcTig
TM
180 is designed as a professional welding tool, and with correct use and
maintenance, the robust design will provide reliable service throughout its life.
Please read this operation manual completely before using the machine!
Protective safety equipment must be used at all times when using this equipment!
1.1. General product prole
MinarcTig
TM
180 is designed to be a compact and efcient direct current TIG/MMA
machine. Extremely light in weight for its high 180 A output power, MinarcTig
TM
180
is easy to carry to the work place with either the inbuilt moulded carry handle or the
shoulder strap provided. The machine is suitable for a range of welding applications
and environments including operation with long power cables. It is also suitable for
generator use on construction sites.
1.2. About welding performance
MinarcTig
TM
180 is a precise welding tool and will provide high quality results time
after time provided the correct operational procedures are followed. Welding quality is
not only inuenced by the machine itself. Personal expertise, ancillary equipment and
consumables also play an essential role as does the correct, fused supply power.
Welding is carried out when an electric arc is established between the welding
electrode and work piece. Welding is not possible unless the equipment is correctly
set-up, including the ‘earth return lead’ attached to the work piece. This return lead
creates the welding ‘circuit’ that allows the welding current to ow. Please check the
earth return lead clamp is on the work piece to be welded, and that the area of the clamps
contact is clean and free from paint.
MMA welding
The MMA welding process is simple in operation. A coated MMA electrode is short
circuited to the work piece and the resulting electric arc creates a molten pool into which
the electrode wire melts. The coating around the electrode burns to create a protective
gaseous atmosphere and slag, which directly protects the molten weld pool from
atmospheric contamination. The slag oats on the molten weld pool and solidies on the
surface of the resulting weld bead, protecting the cooling weld. The burning electrode
is moved slowly along the weld seam. The speed of travel is directly proportional to the
size of the electrode and welding current selected. The slag is nally removed with a
chipping hammer to reveal the weld (Always use eye protection).
