Technical Gas Ar-He Blend — engineered argon-helium shielding and process blends for working industry
A technical gas Ar-He blend is designed around the process, not just the label. REAL GAZ mixes argon and helium at set ratios such as 90/10, 70/30 and 50/50, giving fabricators a predictable arc profile for MIG, TIG, plasma and laser applications on stainless steel, aluminium and nickel alloys.
Because the gas is blended in a controlled plant and not on the line, composition does not drift as the cylinder empties.

Blends are classified under EN ISO 14175, prepared with reference to ISO 6142, and supported by industrial and technical data sheets describing recommended flow rates.
🏭 Where Technical Ar-He Blends Are Used
- 🔧 Pipe and vessel welding — helium additions give wider, flatter beads and good wall fusion on pressure equipment;
- 💡 Laser welding — helium suppresses plasma plume formation so more energy reaches the workpiece and penetration improves;
- 🛠️ Plasma processes — argon-helium offers a hotter, more constricted plasma for clean cuts in thick non-ferrous plate;
- 🚢 Shipbuilding and rail — aluminium hull panels and rolling-stock sections are joined at higher speed with fewer defects;
💡 Why Choose REAL GAZ
- ✅ Process-led recipes — ratios are chosen from your material and joint design rather than from a fixed catalogue;
- 🧪 Stable flow behaviour — composition stays constant from first to last bar, which keeps parameters in range;
- 📦 Flexible supply — single cylinders, 12-cylinder bundles and cylinder rental fit workshops of every size;
- 🔒 Documented lots — each batch is traceable to filling date, analysis and cylinder number;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- inline blending with mass-flow control;
- post-fill composition analysis;
- dew point check on every lot;
- outlet valve inspection and leak test.
Cylinders are tested and certified to EN 1964 and ISO 9809, and loads travel under ADR / UN regulations.
📋 Setting Up the Blend on the Line
Start from the data sheet flow rate and adjust in small steps, watching bead width, spatter and porosity. Helium blends need roughly 1.5 to 2 times the flow of pure argon for comparable shielding because the gas is lighter and disperses quickly. Check hoses for leaks and replace permeable rubber lines with suitable low-permeation tubing, since helium escapes easily through weak connections. Keep drafts away from the weld zone, and purge the line for several seconds before striking the first arc. If porosity appears, our technicians can review travel speed, nozzle size and blend ratio with you and suggest the next trial.
