PRESENTATION
Thank you for choosing this machine. To get the best from your machine, please read the following carefully :
The SMARTMIG is a traditional machine for welding semi-automatic MIG/MAG (DC current), and MMA (SMARTMIG
3P Only). These machines can weld all types of wire : Steel, Stainless Steel, Aluminium, flux (no gas). The
SMARTMIG 3P is capable of welding electrodes up to 3.2mm.
Adjustment and Setting of these machines is easy with their
SMART feature
.
ELECTRICITY SUPPLY
This machine is supplied with a 16A plug (type CEE7/7). The machine must be connected to an
EARTHED
power
supply of 230V (50/60 Hz) The absorbed current (I1eff) is indicated on the device at maximum usage. Check that
the power supply and its protection (fuse and/or circuit breaker) are compatable with the current needed for use
(SMARTMIG 142: 13A fuse ; SMARTMIG 162/3P : 16A fuse). In some countries, it might be necessary to change
the plug to allow maximum performance.
The device must be installed so that the mains socket is always accessible.

SEMI-AUTOMATIC WELDING FOR STEEL / STAINLESS STEEL (MAG MODE) – page 2
These machines can weld Steel and Stainless Steel wires of 0.6/0.8 or 1.0mm (except SMARTMIG 142) (Fig II - A)
The machine is delivered equipped to function with Ø 0.8mm Steel/Stainless steel wire, and the contact tip, roller
throat and the sleeve of the torch supplied are suitable for this application.
Should you wish to use 0.6mm wire, you will need to change the contact tip. The wire reel is reversable (0.6 /
0.8mm) and will need to be inserted into the machine so that the figure 0.6 is visible. For welding with Ø 1.0mm
wire, you will need to use a specific roller and contact tip.
For welding with Steel or Stainless Steel it is necessary to use
For use with Steel/Stainless Steel, the gas requirement is Argon + CO
2
. (Ar+CO
2
).. The proportion of CO
2
required
will vary depending on the use. For specific gas requirements, please contact your gas distributor. The gas flow in
steel is between 12 and 18 Litres/minute depending on the environment and experience of the welder.
SEMI-AUTOMATIC WELDING FOR ALUMINIUM (MIG MODE) – page 2
The SMARTMIG 162 & 3P are delivered equipped for welding with Aluminium wire Ø 0.8 or 1.0mm (fig II-B)
The SMARTMIG 142 is delivered equipped for welding Aluminium of Ø 0.8mm (Occasional and non-intensive). In
this case the wire used should be stiff to facilitate wire feeding.
For use with aluminium, the gas requirement is pure argon (Ar). For the specific gas requirements please contact
your distributor. The gas flow in Aluminium is between 20 and 30 Litres/minute depending on the environment,
and the experience of the welder.
Below are the differences between welding with Steel and Aluminium :
- Specific rollers are needed for welding with Aluminium.
- Adjust the pressure of the drive rolls to prevent the wire being crushed.
- Only use a capilliary tube for welding with Steel or Stainless Steel.
- Use a special Aluminium Torch with a teflon sheath to reduce friction.
DO NOT
cut the sheath close to the joint
, it is used to guide the wire from the the rollers.
- Contact Tube : Use a special aluminium contact tube specific to the diameter of wire being used.
GASLESS WIRE WELDING (FIG. III, PAGE 2)
These machines are capable of "Gasless" wire welding (cored wire) provided that the polarity is reversed.
To do this, turn the machine off, open up the machine
⑭
and make the electrical connections described in
Figure C of the page below. The Machines are originally configured for Gas welding.
