Argon Shield Mixture for welding — choose the right mixture for each welding process
Argon Shield Mixture for welding from REAL GAZ is prepared to protect the arc and weld pool while shaping penetration and bead profile.
The mixture you choose influences spatter, speed, fusion and finish, so guidance is part of our service.

For MAG welding of mild steel, argon with 8 to 18% CO₂ is usual. For stainless steel, argon with 2% CO₂ or 2% oxygen retains corrosion resistance. For aluminium MIG, pure argon or argon with helium is selected. Pulsed transfer modes generally prefer leaner active content, whereas short-arc work on thin sheet tolerates somewhat higher CO₂. Always compare with the wire manufacturer's recommendation.
Some practical starting points may help. Use argon with about 18% CO₂ for general MAG work in the short-arc or globular range on carbon steel, argon with 8% CO₂ for spray and pulse, and argon with 2% oxygen or CO₂ for austenitic stainless. For aluminium, pure argon suits thinner sections, while adding 25 to 50% helium suits thick plate. Trial welds and macro examination remain the best confirmation for each procedure. Where welders move between thin sheet and thick plate, a medium CO₂ level often offers a sensible compromise.
REAL GAZ supplies this product according to EN ISO 14175, ISO 6142 and supporting documentation for EN ISO 15614 procedures, suitable for industrial welding.
🏭 Where Argon Shield Mixtures Are Used
- 🔥 MAG welding of steel — Ar-CO₂ mixtures give good wetting and controlled penetration;
- 🍶 Stainless steel fabrication — low-active mixtures minimise oxidation and preserve a clean seam;
- ✈️ Aluminium MIG welding — argon and argon-helium mixtures promote smooth transfer and sound fusion;
- 🛠️ Thin sheet repair — leaner mixtures reduce burn-through and heat distortion.
