1. Introduction
In case of MIG/MAG welding method the arc is generated between the automatically fed
welding wire
and the
working piece
, shielding in CO
2
gas or gas mixture.
The machine is able to weld unalloyed and low alloyed
steel plates
. When welding thin car chassis, the
application of
gas mixture
is recommended, whilst in other cases, when deep penetration is required,
pure CO
2
renders better solution.
Important advantages of this technology are high
heat concentration
and
current density
so warp of the
material is very low.
Additional advantages:
♦
high welding speed, quick melting,
♦
wide range of welding parameters,
♦
deep penetration, high melting rate,
♦
easy automation,
♦
ability to weld of thin plates, roots, etc.,
♦
no slag on the welded seam.
The equipment consists of two,
separated
units: the
Power Source
and the
Wire Feeder
, and they are
connected with cables and hoses of 10 m long. The
power source
is designed to constitute a compact unit with
the
gas bottle
and the
undercarriage
fixed to it.
Main parts of these units:
♦
Metal housing with wheels and fan
♦
Metal housing with central torch adaptor
♦
Main transformer (of flat static characteristic)
♦
Wire feeding unit with motor
♦
Rectifier bridge
♦
Solenoid (gas) valve
♦
Choke for smoothing the current
♦
Electronic control unit
♦
Auxiliary transformer and contactor
♦
Connecting cables and hoses (10 m)

3. Transport and storage
The manufacturer delivers the equipment with standard
accessories
and
undercarriage
mounted. Before
transport, the machine has to be secured against tipping over and protected against adverse effects of the weather.
It must be stored at dry, covered places.
It shall be loaded and unloaded by
lift trucks
.
Protect it against moisture and mechanical shock carefully!
