Stainshield 2.5 MIG welding gas mix used for MIG welding stainless steel is an Argon/CO2 gas blend. General purpose mixture, good wetting action, smooth weld surface.

CO2 is a reactive gas used in MIG welding. Carbon dioxide is the only reactive gas that does not require the addition of an inert gas, like argon. CO2 is the lowest cost shielding gas, making it a popular choice for cost control.

Argon is generally the preferred gas for aluminium welding, whether it’s TIG welding gas or MIG welding gas. Use a pure argon shield when welding aluminium base metals 15mm thick or less. When welding thicker metals, a helium mix can useful to increase the penetration.

Our range of MIG welding gas and MIG welding gas mixtures can help optimise your welding jobs. Get your MIG and TIG welding gas with free delivery.

When TIG welding, an arc is formed between the non-consumable tungsten electrode and the metal. TIG welding gas flows through the torch, shielding the electrode and molten weld pool. Filler wire is added seperately to the weld pool, if used.

What does MIG Stand for in Welding - What Does MIG Welding Mean

Gas metal arc welding (GMAW) refers in part to metal inert gas (MIG) welding, which is a welding process in which an electric arc forms between a consumable MIG electrode wire and the metal being welded, with a MIG welder. The electric arc heats the metal, creating a weld pool that causes them to melt and bond.

MIG welding gas mix is for a MIG welder. A MIG welder uses an arc welding process that joins metals by melting them with heat, using MIG welding gas used as shielding gas for MIG welding. 

What Gas is Used for MIG Welding - Shielding Gas for MIG Welding

Argon is typically the preferred gas for welding aluminium, with either TIG welding or MIG welding. Use a pure argon shield when welding a thin aluminium work surface under 15mm. When welding thicker aluminium, a helium mix can provide increased penetration.

The shielding gas used for MIG welding gas is a MIG welding gas mix of inert gases. Argon is the shielding gas used for MIG welding aluminium and MIG brazing. Argon MIG welding gas replaces the Air (Oxygen) from around the weld pool.

A MIG welding gas mix of active gases is used for MIG welding include CO2 and a MIG welding gas mix of Argon and CO2 gas for MIG welding steel. These active MIG welding gases are typically used for MIG welding most steel but not aluminium.  An Argon-Co2 MIG welding gas mix slightly improves electrical conductivity for increases penetration and allows the weld pool to flatten and flow, so the weld is not appear too tall.

Our shielding gas for MIG welding gas include the Argoshield and Stainshield range, which are MIG welding gas mix formulated by application.

TIG Welding Gas

When TIG welding, an arc is formed between the non-consumable tungsten electrode and the metal. TIG welding gas flows through the torch, shielding the electrode and molten weld pool. Filler wire is added seperately to the weld pool, if used.

TIG welding gas are inert gases used as shielding gases in the TIG welding process. TIG welding gas is typically a mixture of argon with helium, hydrogen and/or nitrogen added for better welding speeds and process stability. You get improved weld quality and less rework time.

Active gases are not used for TIG welding as it causes potential problems with hole blows and excessive burning of the tungsten electrode.

HF Unit for TIG Welding

An HF unit for TIG welding is the typical way of starting the TIG welding arc. It uses HF (High Frequency), which consists of a high voltage spark lasting a few microseconds at several thousand volts.

TIG Welding - GTAW Welding

GTAW is Gas tungsten arc welding which is also known as TIG welding - tungsten inert gas welding. It is arc welding that employs a non-consumable tungsten electrode to produce the arc weld.

TIG welding gas is also used with gas tungsten arc welding (GTAW), using a tungsten electrode and argon shielding gas. Argon shielding gas protects and cools the weld puddle and tungsten from nitrogen absorption and oxidation during TIG welding. TIG welding uses a non-consumable tungsten electrode to deliver the welding arc current.

TIG is an acronym for "Tungsten Inert Gas".

TIG Welding Aluminum - How to TIG Weld Aluminium

To TIG weld aluminium, here are some helpful tips…

  • Wear the proper PPE, including safety glasses, welding helmet, gloves and a welding jacket

  • Use the correct TIG welding gas:

    • Use a pure argon shield when welding aluminium base metals 15mm thick or less

    • When welding thicker metals, a helium mix can useful to increase the penetration

  • Clean off the aluminium oxide layer with a stainless steel wire brush before you begin welding

  • AC polarity acts as a cleaning action to help remove the aluminium oxide layer so you can see the molten weld pool

  • Turn the balance control down for less EN and more EP to help remove oxide during welding and reduce possible peppering

  • The arc becomes more stable at a higher the AC output frequency. 150 to 250 Hz output frequency is good on thin material. For welding thicker materials of 0.375" (9.4mm) and thicker, use an AC frequency of 80 to 120 Hz. 

  • The guideline for aluminium GTAW is the use of 1 amp for every 0.001" (0.25mm) thickness of material. For example, use 100 amps for a thickness of 0.100" (25mm). 

  • Control when filler metal (aluminium TIG welding rods) is added to establish the weld puddle and get correct penetration before adding filler metal

  • Adding more filler metal (aluminium TIG welding rods) is a common technique used to achieve the stacked-coins appearance with GTAW welded aluminium

  • Aluminium conducts heat very well so the heat of the weld puddle can be quickly lost. This requires a lot of heat to establish the weld puddle. Be careful to control the heat to prevent a burn-through or runaway puddle

  • Using a shorter arc length helps localise the heat in a tighter area

  • Always follow the instructions provided by the welding machine manufacturer

Precautions for Safe Handling of Argoshield 5, 16 & 25 MIG Welding Gas Mix

Argoshield welding gas

Use of safe work practices are recommended to avoid inhalation.

Do not drag, drop, slide or roll cylinders.

The uncontrolled release of a gas under pressure may cause physical harm.

Use a suitable hand truck for cylinder movement.

Conditions for Safe Storage of Argoshield® MIG Welding Gas Bottles

(including any Incompatibilities)

Do not store welding gas cylinders near incompatible materials.

Welding gas cylinders should be stored below 45°C in a secure area, upright and restrained to prevent cylinders from falling.

Welding gas cylinders should also be stored in a dry, well ventilated area constructed of non-combustible material with firm level floor (preferably concrete), away from areas of heavy traffic and emergency exits.

Incompatible materials

Moist carbon dioxide is corrosive, hence acid resistant materials are required (e.g. stainless steel).

Certain properties of some plastics and rubbers may be affected by carbon dioxide (i.e. embrittlement, leaching of plasticisers, etc).

Hazardous by-products may be produced when this gas/gas mixture is used in welding, cutting and associated processes.
