Welding Gas Sizes
Welding gas sizes run from small hobby bottles to full trade cylinders. Pick by how much welding you do and how often you want to swap empties.
Benefits & features
Hobby to trade sizes
From small portable bottles for the home garage up to full trade cylinders that cut down changeovers in a busy workshop.
Rent-free cylinders
No monthly hire and no contract, unlike the big-brand rental model. Pay for the gas plus a one-off refundable deposit only.
Fast cylinder exchange
Swap an empty for a full cylinder of the same gas and size in minutes — no waiting on a slow on-site refill.
Hobby, portable and trade cylinders
- Hobby — the smallest bottles. Light to lift and store, ideal for the odd repair, the home garage and occasional jobs.
- Portable — a mid step up. Still easy to carry to the job, but with more gas between changeovers for regular DIY and light fabrication.
- Full trade — the most gas per fill, so far fewer swaps. The choice for busy workshops and anyone welding day in, day out.
Every size comes in pure argon, pure CO2 or argon/CO2 mix, and every size is rent-free with quick exchange.
Bigger cylinder, fewer interruptions
The rule of thumb is simple: buy bigger to cut down changeovers, or smaller to keep it portable. A larger cylinder holds more gas, so you swap it less often and lose less time mid-job — a real saving in a busy workshop.
Because there is no rental on any size, going bigger costs you nothing in hire charges. And if your needs change, you can switch to a different size next time you exchange an empty.

Do bigger cylinders cost more to rent?
There is no rental at all — every size is rent-free. You pay for the gas plus a one-off refundable deposit, whatever the size.
Can I change size when I exchange?
Yes — when you swap an empty you can move up or down a size to match how your welding has changed. Just ask at the point of exchange.
