| Carbon Steel |
75% Argon / 25% CO2 |
Less than 1/8" thick; high welding speeds without burn-through; minimum distortion and spatter. More than 1/8" thick: minimum spatter; clean weld appearance; good puddle control in vertical and overhead positions. |
| SteelMIX® |
Offers less spatter, less distortion and better puddle control than 75% Argon / 25% CO2 |
| CO2 |
Deeper penetration; faster welding speeds. |
| Low Alloy Steel |
60-70% Helium / 25-35% Argon / 4-5% CO2 |
Minimum reactivity; excellent toughness; excellent arc stability; wetting characteristics and bead contour; little spatter. |
| SteelMIX® Extra |
Out performs all gases on dirty steel. Excellent on mill scale, painted or oily material. Allows higher travel speed for automated applications. |
| SteelMIX® |
Fair toughness; excellent arc stability; wetting characteristics and bead contour; little spatter. |
| Stainless Steel |
90% Helium / 7.5% Argon / 2.5% CO2 |
No effect on corrosion resistance; small hea-affected zone; no undercutting; minimum distortion. |
| StainMIX 3 |
Smoother arc with lower hear input and less spatter. |
|

|
| Aluminum |
Argon |
0 to 1" thick; best metal transfer and arc stability; least spatter. Also for GMAW-Pulse Spray. |
| AluMIX |
1/8 to 1" thick. Better penetration and oxide removal. Much less ozone creation than with straight argon. |
| 25% Argon/75% Helium |
1 to 3" thick; higher heat input than straight Argon; improved fusion characteristics with 5XXX series Al-Mg alloys. Over 3" thick; highest heat input; minimizes porosity. |
| Magnesium |
Argon |
Excellent cleaning action. |
| Carbon Steel. Low Alloy Steel |
Argon/2-5% Oxygen |
Improves arc stability; produces a more fluid and controllable weld puddle; good coalescence and bead contour; minimizes undercutting; permits higher speeds than pure Argon. Also for GMAW-Pulse Spray. |
| SteelMIX® 3 |
Low-energy mix ideal for thinner gauge material (up to 1/8" thick). |
| CO2 |
High-speed mechanized welding; low cost manual welding. |
| Argon/5% CO2 |
For faster freezing puddle with GMAW-Pulse Spray. |
Stainless Steel |
Argon /1% Oxygen |
Improves arc stability; produces a more fluid and controllable weld puddle; good coalescence and bead contour; minimizes undercutting on heavier stainless steels. Also for GMAW-Pulse Spray. |
| Argon / 2% Oxygen |
Provides better arc stability, coalescence and welding speed than 1% Oxygen mixture for thinner stainless steel material. Also for GMAW-Pulse Spray |
| StainMIX |
Versatile two-component gas for spray and pulse spray. |
| Copper, Nickel and their alloys |
Argon |
Provides good wetting; decreases fluidity of weld metal for thickness up to 1/8”. |
| Argon/Helium |
Higher heat inputs of 50 & 75% Helium mixtures offset high heat dissipation of heavier gauges. |
| Titanium |
Argon |
Good arc stability; minimum of weld contamination; inert gas backing is required to prevent air-contamination on back of weld area |
