ARCAL™ Welding Gas
ARCAL™ argon-based welding gases for MIG, TIG, and specialty processes.
ARCAL™ from Air Liquide is the premium shielding gas for professional welding. Argon-based blends for MIG, TIG, and specialty processes. Consistent composition ensures predictable weld quality across stainless steel, aluminium, and precision applications. Available in SMARTOP™ and EXELTOP™ cylinders.
Why Air Liquide
Premium Gas for Precision Welding
ARCAL™ formulations are precision-blended for carbon steel, stainless, and aluminium. 100% batch testing ensures purity and consistency. No cold welds. No porosity. Every cylinder meets specification.
Consistent Composition, Every Cylinder
Batch-to-batch consistency means your welds look and perform identically job-to-job. Precision blending (±0.5%) is tighter than industry standard (±2.0%). Quality that builds reputation.
Professional Support & Training
ARCAL™ comes with welder certification training, technical data sheets, and application advice. We match the right ARCAL™ blend to your material and process. Dedicated technical support.
Aerospace Fabrication — Precision MIG Welding (100 kg/month)
To understand the impact, here is an example from an actual customer.
Scenario: Aerospace component fabricator, Melbourne. 100 kg of ARCAL™ 75/25 (argon-CO2) monthly. Previous supplier: generic blend with variable quality, poor weld appearance, high rework rate.
Air Liquide approach: Premium formulated ARCAL™ with 100% batch testing. Precision purity (99.99% argon base). Monthly delivery on schedule. Dedicated technical support.
Weld defect rate improved from 2.1% to 0.3% (fewer reworks). Rework labour reduced from 40 hours/month to 8 hours/month (30-hour monthly saving). Quality consistency enables customer confidence in precision welds. Estimated annual value: $45,000–$60,000 (rework elimination + labour efficiency + customer satisfaction). Your results may differ.

| Product | Benefits |
|---|---|
| ARCAL™ Mx (Carbon Steel MIG) |
75% argon + 25% CO2 or 80% argon + 20% CO2. Deep penetration, fast travel speed, and a clean appearance. Standard blend for structural steel and heavy plate welding. |
| ARCAL™ 1 (Stainless Steel TIG) |
100% argon with precision purity. Produces an oxide-free finish with excellent corrosion resistance. Ideal for food equipment, aerospace components, and high-visibility work. |
| ARCAL™ 3 (Aluminium TIG) |
Argon with an optimal helium blend. Delivers clean, strong welds on lightweight aluminium. Best suited to aerospace, marine, and automotive aluminium structures. |
| ARCAL™ Dual (Multi-Material) |
75% argon + 25% CO2 formulation. Provides versatility for mixed-material jobs where operators switch between carbon steel and stainless steel. |
Questions Buyers Ask
What's different about ARCAL™?
Premium formulation with tighter tolerances, 100% batch testing, and precision purity. ARCAL™ ensures consistent composition; industry standard blends show ±2.0% variation.
Will ARCAL™ improve my weld appearance?
Yes. Consistent composition reduces defects and improves aesthetics. Precision blend eliminates the cold welds and porosity common with lower-purity shielding gases.
What ARCAL™ blends are available?
Carbon steel (75/25 or 80/20), stainless (100% Ar), aluminium (Ar + He), and dual-purpose (75/25). We can also create custom blends for specialty applications.
Is ARCAL™ available in cylinder sizes I need?
Yes. SMARTOP™ (on/off lever, standard regulator) and EXELTOP™ (built-in regulator, quick-connect) available in all standard sizes.
How do I order ARCAL™ gas?
Request a quote online or call 1300 427 427. Specify your volume, material type, current supplier specs, and preferred cylinder system (SMARTOP™ or EXELTOP™).
What training do you provide?
Certified welder training included with every new account. Technical data sheets and application guidance available. Annual refresher training at no charge for contract customers.
