Welding Gases In Toronto & The GTA
Welders Supply & Gases supplies welding gas cylinders across Toronto and the Greater Toronto Area. Order argon, CO₂ or a specified shielding mixture for your welding process, along with oxygen and acetylene for oxy-fuel work. Our Scarborough facility provides cylinder refills and exchanges, with pickup and delivery options for local welders.
Gas Supply For Welding Shops
Running MIG and TIG equipment in the same shop can mean keeping several gases on hand. We supply individual cylinders and recurring orders for businesses using different welding processes. Whether you replace a cylinder occasionally or need several delivered each week, talk to us about available sizes and replenishment arrangements.
Welding Gases We Supply
Gases For Different Welding Applications
- MIG welding
For mild-steel MIG welding, common shielding gases include CO₂ and argon/CO₂ mixtures. The welding mode matters: a mixture used for short-circuit welding may differ from one specified for spray or pulsed welding.
We supply pure CO₂, C25 and C10 for the processes that call for them. When ordering for a new machine or changing wire, check the gas recommendation in the equipment instructions and consumable data sheet.
- TIG welding
TIG welding, also called gas tungsten arc welding or GTAW, commonly uses pure argon. The shielding gas protects the tungsten electrode and molten weld pool from the surrounding air.
Argon is used for TIG welding of steel, stainless steel and aluminum. Some procedures specify an argon/helium mixture. Keep the TIG gas specification separate from any argon/CO₂ mixture used for steel MIG work.
- Stainless steel and aluminum welding
Stainless-steel TIG welding commonly uses argon. Stainless-steel MIG welding requires a suitable shielding mixture selected for the wire and welding mode.
Aluminum MIG welding commonly uses pure argon, with argon/helium mixtures used for certain applications. When switching between metals on a multiprocess machine, check the gas requirement for each task. A mixture intended for mild-steel MIG welding may be unsuitable for the next material.
- Oxy-acetylene welding and repair work
Oxy-acetylene equipment uses oxygen and acetylene to produce the welding flame. The gases also support brazing, heating and cutting when used with equipment designed for those tasks. We supply both gases, so you can include your torch requirements in the same order as your shielding gases.
Request A Quote For Welding Gas Supply
Contact Welders Supply & Gases with your required gas or mixture, cylinder quantity and location. Let us know whether you need a refill, an exchange or a new cylinder, and whether you prefer pickup or delivery. Our team will check availability and prepare a quote.
Choosing The Right Welding Gas
Start with the process and the metal you are welding. For wire-fed welding, the wire classification and selected welding mode help determine the required shielding gas. A machine capable of several processes may need different gases for each one.
Once the gas is specified, consider how much you use and how often you can arrange replenishment. Include your current cylinder size when requesting a quote. A photograph of the cylinder label can also help identify the gas or mixture you have been ordering.
For work that specifies a particular gas grade or requires supporting documentation, mention those requirements before placing the order.
Which Gas Is Used For Each Welding Process?
Use the table below to prepare your inquiry. The gas you order should match your welding procedure, consumable requirements and equipment specifications.
| Welding Process | Commonly Used Gas |
|---|---|
| MIG welding of mild steel | CO₂ or an argon/CO₂ mixture matched to the wire and welding mode |
| TIG welding of steel, stainless steel or aluminum | Pure argon; argon/helium mixtures for selected applications |
| MIG welding of aluminum | Pure argon or an appropriate argon/helium mixture |
| MIG welding of stainless steel | A stainless-specific shielding mixture suited to the wire and equipment |
| Gas-shielded flux-cored welding | CO₂ or an approved shielding mixture, as specified for the wire |
| Oxy-acetylene welding | Oxygen and acetylene |
Welding Gas Cylinders & Supply Options
1
Cylinder purchase and rental
We supply welding gas cylinders for purchase or rental. Available argon and MIG-mix cylinder capacities include 20, 40, 60, 125 and 300 cubic feet. Confirm the gas and size required when ordering, as availability can differ between products.
2
Cylinder refills and exchanges
Refill and exchange services are available at our Scarborough facility. For a cylinder you have not brought to us before, call with its size, gas type and ownership details. Our team can confirm the available service before you visit.
3
Recurring orders and business accounts
Businesses using several welding gases can include them in one supply enquiry. Ask about a business account and delivery arrangements for regular orders. Your usual cylinder quantities and reorder frequency will help us prepare pricing for the supply you need.
Gas Quality, Cylinder Information & Safety
Check the cylinder label to identify its contents. Cylinder colour alone should not be used to identify a gas. Read the Safety Data Sheet for the gas or mixture, and follow the equipment manufacturer’s instructions and applicable workplace requirements, including WHMIS. Ask our team for product specifications or cylinder information needed for your order. Before collecting cylinders, confirm the handling and transport arrangements required for your pickup.

Why Welders Choose Welders Supply & Gases
Welders Supply & Gases is a family-owned business with a warehouse and cylinder-filling facility in Scarborough. You can speak directly with our staff about a refill, a new cylinder or an ongoing delivery order.
We also carry welding equipment and consumables. Customers ordering gas can discuss those requirements at the same time, including regulators and other equipment needed for their setup.
FAQs
What gases do you supply for welding?
We supply pure argon, CO₂, argon/CO₂ mixtures, helium and argon/helium blends for relevant welding processes. Oxygen and acetylene are available for oxy-acetylene work. Tell us the gas or mixture specified for your process, and we can confirm cylinder options, availability and pickup or delivery arrangements.
What gas is used for MIG welding?
The gas depends on the metal and welding mode. Mild-steel MIG commonly uses CO₂ or an argon/CO₂ mixture. Aluminum MIG commonly uses pure argon, while stainless-steel MIG requires a suitable stainless-specific mixture. Follow the recommendation for your wire and equipment when selecting a gas.
What gas is used for TIG welding?
Pure argon is commonly used for TIG welding of steel, stainless steel and aluminum. Some applications use an argon/helium mixture. Provide the gas specification from your welding procedure when ordering, particularly where the work requires a certain blend or purity grade.
What is argon/CO₂ welding gas used for?
Argon/CO₂ mixtures are used as shielding gases in specified steel welding processes. We supply C25 and C10, which contain different proportions of CO₂. These blends affect the arc and weld differently, so order the composition required for your welding mode and wire rather than treating them as interchangeable.
What welding gas cylinder sizes are available?
Our argon and MIG-mix range includes capacities such as 20, 40, 60, 125 and 300 cubic feet. Other gases have their own cylinder options. Tell us the gas you need and your current cylinder size so we can confirm an available purchase, rental or refill option.
Can you refill or exchange my existing welding gas cylinder?
Refill and exchange services are available, subject to the cylinder being suitable for the service. Call with the gas type, cylinder size and ownership details before your first visit. For a rented cylinder, check the ownership agreement before arranging service through a different supplier.
Do you deliver welding gases across the GTA?
Yes. We deliver to welding shops and other businesses across Toronto and the GTA, including Vaughan, Markham, Richmond Hill and Newmarket. Send your address and required gases when requesting a quote. For recurring supply, include your usual order quantities and preferred receiving hours.
How much does welding gas cost?
Pricing depends on the gas or mixture, cylinder capacity and whether you are purchasing, renting, refilling or exchanging a cylinder. Delivery requirements also affect the quote. Send your gas specification and cylinder details for current pricing, including the supply arrangement you need.
