Gas Science
The chemistry and physics behind shielding gas behavior. Understanding these mechanisms helps you diagnose problems and make better gas decisions.
Gas Properties
- Argon Properties — Why argon dominates shielding gas
- CO₂ Dissociation — What happens when CO₂ enters the arc
- Helium Heat Boost — How helium increases heat input
- Oxygen Additions — Small percentages, big arc effects
- Nitrogen & Austenite — Stabilization effects in stainless
- Hydrogen Embrittlement — Risks and prevention
