Some Popular Industrial Welding Gases Include:

Gas	Ionization Potential (eV)	Gas Characteristic	Limiting Properties	Positive Properties	Arc characteristics / Mode of transfer	Arc Penetration
Argon	15.759	Inert	Low thermal conductivity	Suited for thin materials...	Used in all modes of transfer	Wide/deep
Helium	24.587	Inert	Higher heat input and requires higher flow rates due to lighter molecule	High thermal conductivity - which can improve travel speed and deposition rates	Used in all modes of transfer	Very wide/shallow, adds instability
Carbon Dioxide	13.769	Oxidizing	Forms silicon islands	Promotes wider penetration through dissociation and re-combination	Globular transfer only	Wide/deep
Oxygen	13.618	Highly Oxidizing	Contributes to surface oxidation	Reduces current transition and increases weld puddle fluidity - Works well with thin gauge materials	Used in all modes of transfer	Small percentage adds to arc stability
Hydrogen	13.598	Highly Reducing	Use only with SS - Induces cracking in carbon and low alloy steels	Reduces surface tension and increases travel speeds	Used in all modes of transfer	Narrow/focused energy
Nitrogen	14.543	Inert	Use only with 300 SS - Can cause crack sensitivity in non stainless applications	Improves arc stability	Used in all modes of transfer	Promotes adequate fusion and penetration while maintaining SS properties

Argon/Carbon Dioxide – ARCgas’s ARCGold Blends

Argon/carbon dioxide (Ar/CO2) blends are a cornerstone for many welding applications and are a key part of our industrial gas supply. These versatile blends are primarily used in Gas Metal Arc Welding (GMAW), also known as MIG welding. The argon provides a stable arc and excellent bead appearance, while the carbon dioxide increases the arc temperature and penetration, leading to stronger, more reliable welds. In Flux-Cored Arc Welding (FCAW), specifically with gas-shielded wires, these blends also provide the necessary shielding to protect the molten weld pool from atmospheric contaminants. This dual-purpose use makes these blends essential for fabricators, manufacturers, and welders who demand high-quality results for a wide range of projects, whether they’re using GMAW or gas-shielded FCAW processes.

Core Applications

Argon and carbon dioxide blends are commonly used in welding applications for structural steel, agricultural equipment, and machinery. Lower carbon dioxide concentrations are ideal for pulsed arc or spray arc welding, while higher concentrations (above 20%) are better suited for short arc welding and certain gas-shielded flux-cored wires.
