APAC 18 Welding Gas

About APAC 18

APAC 18 — 82% argon / 18% carbon dioxide — is the most widely used general-purpose MIG gas for mild steel in Australia. The 18% carbon dioxide gives strong, reliable penetration and a forgiving, stable arc that copes well with less-than-perfect fit-up and out-of-position work, which is why it is the default workshop and maintenance gas. It handles short-arc through to spray transfer across a broad range of material thicknesses.

APAC 18 is supplied in E-size and G-size cylinders, charged to 19,000 kPa with an AS 2473 Type 10 outlet, and delivered across Melbourne. Compare the full welding range →

⚠ Main Hazards

• Simple asphyxiant — the argon, CO₂ and oxygen in this mixture are heavier than air and can pool in pits, trenches and low or confined spaces, displacing breathable oxygen with no warning.
• No warning properties — colourless, odourless and tasteless. The gas cannot be detected by human senses at dangerous concentrations.
• High-pressure stored energy — cylinders are charged to 19,000 kPa. Secure cylinders upright, fit the valve cap for transport and inspect the valve before use.
• Rapid release of gas can cause cold burns to skin or eyes on contact with escaping gas, valves or regulators.
