When you're halfway through a big welding job and the gas bottle runs out, you don't want to waste time hunting down a refill. That's where stocking up on Coregas makes sense. Whether you're a fabricator, mechanic, or serious DIYer working on automotive or metal projects, having reliable gas bottles on hand keeps your work moving without delays.
Tool Kit Depot stocks a range of industrial gas cylinders to suit different trades and applications. From argon for TIG welding stainless and aluminium, to oxygen for oxy cutting and heating, we've got the gas you need to get the job done right. These bottles are built for trade use and come ready to go, so you can get straight back to work.
If you're running a workshop or need multiple bottles for site work, we can help you sort the right setup. Argon bottles are ideal for clean, precise welds on non-ferrous metals, while oxygen cylinders pair with acetylene for cutting through thick steel plate or heating bolts for removal. Having the right gas on site means you're not cutting corners or compromising on quality.

Coregas FAQ
What gas cylinders does Coregas supply?
Industrial and trade gas cylinders cover welding, cutting, heating, and specialty applications. Common cylinders include argon for TIG welding, oxygen for oxy cutting, acetylene for heating and cutting, and various mixed gases for MIG welding. Each cylinder is sized to suit different job requirements, from portable bottles for site work to larger cylinders for workshop setups. You can pick up smaller bottles for mobile work or full-sized cylinders for permanent workshop installations.
What is Coregas argon used for?
Argon is primarily used for TIG welding stainless steel, aluminium, and other non-ferrous metals. It's an inert shielding gas that protects the weld pool from contamination, resulting in clean, strong welds with minimal spatter. It's also used in MIG welding when mixed with CO2 or other gases, depending on the base material you're working with. The gas prevents oxidation during the welding process, which is critical for maintaining weld integrity on sensitive metals like aluminium or thin stainless.
Can you refill Coregas bottles?
Yes, gas bottles can be refilled or exchanged depending on the bottle ownership model. Some bottles are refillable through exchange programs where you swap your empty cylinder for a full one, while others may require direct refilling at an authorised depot. Check with Tool Kit Depot or your local supplier to confirm the refill options available for your specific cylinder type. Most trade setups use exchange bottles for convenience, which means you're never waiting around for a refill.
What's the difference between argon and oxygen cylinders?
Argon cylinders contain inert gas used for shielding during TIG and MIG welding, while oxygen cylinders are used in oxy-fuel cutting and heating applications. The two gases serve completely different purposes: argon protects molten metal from oxidation, whereas oxygen supports combustion when paired with acetylene or propane for cutting through steel. Never interchange regulators or fittings between the two, as they're designed for different pressures and uses. Argon runs at lower pressures and uses different thread types to prevent cross-connection accidents.
How long does a gas cylinder last?
Cylinder lifespan depends on the size of the bottle, the flow rate you're using, and the type of work you're doing. A small argon bottle might last 2–4 hours of continuous TIG welding, while a larger cylinder could handle days or even weeks of intermittent use. Oxygen cylinders used for cutting will deplete faster under high flow rates, often lasting 1–3 hours of continuous cutting depending on tip size and material thickness. If you're running a busy workshop or doing extended site work, it's worth keeping a spare bottle on hand to avoid downtime.
