Shielding mixture for MAG welding of stainless steels.
. Compared to Ar/CO2 mixtures, it allows spray arc to be reached at lower currents. It produces a spray transfer (fine mist) of the filler metal and reduces the surface tension of the weld pool.
The fluidity of the weld pool ensures good wetting of the edges to be joined and prevents the formation of undercuts.

This gas also allows welding of steels for thicknesses up to 3 mm for non-professional use.

- especially suited for spray arc welding
- good arc stability
- good welding speed

The contract-free refillable gas cylinder is the ideal solution for welding without committing to a costly annual rental. You buy the cylinder once, then refill it freely: no subscription, no monthly fee. Discover our range of contract-free argon, argon-CO₂, oxygen and acetylene cylinders, designed for tradespeople and individuals who want to control their gas budget.

The principle of the contract-free cylinder

With traditional suppliers, a gas cylinder is rented: you pay a deposit and an annual fee, sometimes for years, even if you weld infrequently. The contract-free gas cylinder reverses this logic: the cylinder belongs to you. When it is empty, you have it refilled or exchange it for a full one, with no fixed-term commitment. Over the long term, the savings are often considerable.

For which gases and which processes?

Our range covers the main needs of the welder. For TIG welding, choose a pure argon cylinder, an inert gas essential to the process. For MIG/MAG steel welding, a contract-free argon-CO₂ cylinder provides weld pool protection. For flame welding and oxyfuel cutting, oxygen and acetylene cylinders fuel the oxyacetylene torch. Whatever your process, there is a suitable refillable cylinder available.

Economic advantages

The main advantage of a contract-free MIG gas cylinder is financial. No annual fee running all year, no rental invoice to pay regardless of your usage. For an occasional welder, the calculation is straightforward: renting a standard cylinder can, over a few years, exceed the purchase price of an owned cylinder. The contract-free argon cylinder is therefore particularly cost-effective for moderate to regular use.

Day-to-day flexibility

Beyond price, freedom is a major advantage. You refill whenever you want, wherever you want, with no administrative procedures or contracts to cancel. You are not tied to any single supplier. This flexibility appeals to travelling tradespeople as well as experienced DIY enthusiasts, who appreciate managing their gas supply with complete independence.

Choosing the right capacity

Contract-free 4 m³ argon cylinders and other sizes are available in several capacities. For occasional use, a small cylinder is sufficient and easy to store. For a workshop that welds regularly, a larger capacity reduces the frequency of refills. Assess your consumption: gas flows throughout the entire duration of the arc, particularly in TIG and MIG welding.

The regulator: an essential accessory

A cylinder should never be used without a pressure regulator/flowmeter, which regulates the pressure and sets the gas flow rate. Check that the fitting is compatible with the cylinder and gas type. A correctly set flow rate is the key to effective weld pool protection, and therefore a sound weld bead, whether you are welding by MIG-MAG or TIG.

Safety and storage

Like any compressed gas cylinder, the contract-free refillable cylinder must be stored upright, secured, in a ventilated area away from any heat source. Close the valve after use, transport it secured on a trolley and check the fittings for leaks. These precautions are mandatory.

Refill or exchange: how does it work?

With a contract-free gas cylinder, two supply methods are available. Refilling means having your own cylinder filled at an approved centre. Exchange means returning your empty cylinder and leaving with an equivalent full one, without any wait. In both cases, you only pay for the gas, never a rental fee. Since the cylinder remains your property, you manage your stock freely and can switch service point at will. This flexibility, combined with the absence of a subscription, explains the success of contract-free argon and argon-CO₂ cylinders among tradespeople and individuals who want to control their gas budget while remaining fully independent in their gas supply.

Our recommendation

For those who weld occasionally or regularly without wanting to make a commitment, the contract-free refillable gas cylinder is the most economical and flexible solution. Choose the gas suited to your process (argon for TIG, argon-CO₂ for MIG steel, oxygen-acetylene for flame welding) and the capacity that matches your usage. Browse our selection of contract-free cylinders and free yourself from the constraints of rental.

Frequently asked questions

How does a contract-free gas cylinder work?

The cylinder belongs to you (unlike a rental). When it is empty, you have it refilled or exchange it for a full one, with no fixed-term commitment or annual fee. You only pay for the gas, and manage your supply freely.

Is it more economical to buy a contract-free gas cylinder?

For occasional to regular use, yes. A standard rental imposes an annual fee that runs all year, even when unused. Buying a contract-free cylinder eliminates this subscription: over a few years, the savings often exceed the purchase price of the cylinder.

Which gas should I choose for a contract-free refillable cylinder?

According to your process: pure argon for TIG, an argon-CO₂ mixture for MIG-MAG steel welding, oxygen and acetylene for flame welding. There is a contract-free refillable cylinder suitable for each of these needs.
