Argon 163 is a mixture of 16% Carbon Dioxide & 3% Oxygen with 81% Argon, and is a smooth running general purpose shielding gas mixture suitable for both the short arc and spray transfer modes and for use with solid wires on mild steels.

Being inert wrt breathing purposes, it is an asphyxiant and must not be inhaled as the 3% Oxygen content is a small fraction of the 21% Oxygen in the air we breathe.

In addition, the 16% Carbon Dioxide component is well over the maximum recommended average exposure level for a healthy employee during an eight hour working shift for 0.5 % (5,000 ppm). This component will have what is referred to as an ‘Intoxication’ effect which coupled with the Argon asphyxiant could raidly lead to a fatality as the normal 21% Oxygen will be depleted & the typical 0.3% Carbon Dioxide will be greatly exceeded.

Applications

• MIG Welding of Mild, Carbon and Low Alloy Steels

• Welding 2 - 22mm thick

• Welding of pipe and tube & rolled sections

• General & light to medium plate fabrication

• Structural steelwork manufacture

• Boat, ship building & bridge construction

• Manufacture of vehicles, heavy trucks, pressure vessels & tanks

Hazards

Argon 163 is a mixture of 16% Carbon Dioxide & 3% Oxygen with 81% Argon, and for all intents & purposes behaves like Argon if breathed instead of air, so it is effectively an asphyxiant.

In addition, the ‘Intoxication’ effect of Carbon Dioxide makes for a ‘more than’ non breathable combination.

In confined poorly ventilated spaces, if allowed to build up and displace the air being breathed, will In high concentrations cause asphyxiation.

Initial symptoms include loss of mobility followed by loss of consciousness.

The affected person will most likely neither sense nor be aware of this which makes it essential that such a situation is to be avoided. It is however non-toxic and non-flammable.

Important Info

Storage Handling & Leaks

  • Make sure the cylinder or Pack when used is matched with the correct regulator and end connectors and of appropriate pressure rating.
  • Inspect the regulator and cylinder valve connections to make sure that they are not contaminated with grease, oil, dirt, water or solvents. Never use grease or oil to lubricate regulators or cylinder valves as this will contaminate the gas.
  • Open (Anti clockwise looking down at the hand wheel, directional arrows are on the hand wheel.)
  • or close a cylinder valve (Clockwise looking down at the hand wheel, directional arrows are on the hand wheel.)
  • by hand using moderate torque to open or close them. Too much closing torque can damage the cylinder valve seat.
  • Only use set spanners or specific tools that are provided by the cylinder supplier to connect accessories.
  • Multi-grips should never be used.
  • Some regulators require a sealing washer in or on the inlet spigot.
  • Check that this is present before fitting the regulator to the cylinder valve outlet
  • Gas cylinders (particularly G & E size) are unstable & must be stored in pallets or racks when not in use & secured when in use by a strap or chain against a wall or secured by a suitable trolley with chain or strap.
  • Use appropriate materials for chains. e.g. plastic coated wire cable, commercial straps, with tensioners,… etc., to secure cylinders.
  • Gas cylinders should not be stored in public hallways or other unprotected areas
  • Store out of direct sunlight and away from sources of heat and ignition; temperatures must not exceed 50 °C.
  • Where cylinder caps are fitted to cylinders (i.e. instead of Cylinder Valve guards.) refit these cylinder valve caps to the Cylinder thread when the cylinder is not in use.
  • Cylinders should be protected from damage. Do not store cylinders near elevators or gangways, or in locations where heavy-moving objects may strike or fall on them or knock the cylinder over.
  • Cylinders must be stored on surfaces such as suitably drained concrete to prevent the base of the cylinder from rusting from standing in puddles for long periods. Cylinders should be stored, secured in premises to protect them from theft & against tampering by unauthorized individuals.
  • Storage areas must be well-ventilated, cool, dry, and free from corrosive materials.

 

Handling leaks

  • Do not enter an area with high gas leakages without proper PPE or safety equipment.
  • Approach the leak only if qualified to do so.
  • Use readily available techniques like the soap bubble method to detect the leak.
  • If closing the Cylinder Valve does not stop the leak, then relocate the cylinder to a safer well ventilated or outdoor location to allow the venting gas to escape & not build up. i.e. Per Puregas Safety Guidelines.
  • Return the empty cylinder (Or Pack.) if the leak persists or after the gas has been safely vented.
  • Make sure the cylinder is properly tagged indicating the nature, location & date of the leak together with a contact name & phone number for follow up by the gas supplier.
