Selection Guide
Welding cylinders in M.I.G.-M.A.G. materials
1. Mild steels, carbon
carbon steels are welded in d.c. with reversed polarity (wire-electrode connected to the positive pole) exclusively by applying the welding process M.A.G. Applications range from the use of only the CO2, to mixtures Ar-CO2 in various percentages (the most widespread is 80% argon, 20% CO2).
The greater the percentage of Argon present in the mixture, the better are the characteristics and stability of the arc.
The characteristics of the weld are very good and especially in short arc where you get baths of substantial welding which allow applications in all positions.
The use of wires with levels of silicon and manganese allow to eliminate the impurities present in the base material and obtain welds of good quality.
It is necessary to prepare the joints with chamfer with thickness exceeding 3 mm.

2. Stainless steels
Stainless Steels are welded in direct current or pulsed current with reverse polarity (wire-electrode connected to the positive pole) exclusively by applying the welding process M.A.G. The shielding gas used must be composed of mixtures Ar CO2 or Ar O. The percentage of Argon should not be less than 98 % of the mixture to avoid a strong oxidation of the chromium present in the base material.The thicknesses of the joints more than the 2.5 mm must be blunted. The filler material must be particularly suited to the grade of stainless steel to be welded.
For the execution of a good welding is advisable to grinding of the points.

3. Aluminum and its alloys
aluminum and its alloys are welded in direct current or pulsed current with reverse polarity (wire-electrode connected to the positive pole) by applying the method M.I.G.
The shielding gas used is generally pure argon. Can also be used pure helium or mixture of Ar He.
For welding in plane, independently from the thickness, is used the technique of spray-arc or/and pulsed-arc; is used instead the technique short-arc on welding thin shims in vertical positions and at an angle. Given the characteristics of the aluminum is recommended instead of grinding, milling of said points.

4. Other materials
the welding method M.I.G.-M.A.G. is also used on materials such as nickel and its alloys, copper and its alloys; for all these uses direct current with reversed polarity.
As regards the welding of copper on thicknesses higher than 5 mm is advisable to use the method M.I.G. considering however that the intensity of the current must be adjusted according to the position of the welding and the thickness of the joints.
