MJ Gas House
Where argon is used
Stainless steel work
Kitchen equipment, railings, gates and food machinery welded by TIG with pure argon.
Aluminium fabrication
Aluminium window, door and frame makers weld with pure argon.
MIG welding mild steel
An argon and CO₂ mix gives a cleaner weld with less spatter on gates, grills and structures.
Labs and precision work
High purity argon for lab instruments and critical welds.
Which gas for which job
| Metal or job | Process | Gas |
|---|---|---|
| Stainless steel | TIG | Argon |
| Aluminium | TIG or MIG | Argon |
| Mild steel | MIG | Argon and CO₂ mix |
| Mild steel, heavy work | MIG | CO₂ |
| Thick plate, scrap | Gas cutting | Oxygen with fuel gas |
| Stainless, laser cut | Laser cutting | Nitrogen |
| Pipes, AC lines | Purging and testing | Nitrogen |
A general guide. Send us your metal and job and we confirm the gas.
How long does an argon cylinder last?
Most TIG work runs at around 8 to 12 litres per minute. At 10 litres per minute, a 6.8 cubic meter cylinder gives about 11 hours of welding.
Setting the flow higher than needed wastes gas and can pull air into the weld.
Cylinder sizes
| Cylinder | Good for |
|---|---|
| Around 10 litre | Site jobs and small workshops |
| Mid sizes | Regular workshop use |
| Large, holds 6.8 or 9.91 cubic meters | Busy fabrication shops |
| Up to 80 litre | Factories and heavy use |
Litre is the cylinder size. Cubic meter is the gas a large cylinder holds. Medical (MF) and silver cylinders available.
Refill and regulators

Which gas do I need for TIG welding?
Pure argon. It works for stainless steel, aluminium and most other metals.
Pure argon or argon CO₂ mix for MIG?
For mild steel, an argon and CO₂ mix. For aluminium, pure argon.
Can I get my argon cylinder refilled?
Yes. Bring it to our unit or we collect it from your workshop.
Do you sell argon regulators?
Yes, argon flowmeter regulators fitted to your cylinder.
