This oxygen and acetylene tank set includes two new steel cylinders: a 10 cubic foot MC acetylene tank with a CGA200 valve and a 20 cubic foot oxygen tank with a CGA540 valve. Together they supply the two gases an oxy-acetylene torch needs for brazing, cutting, and light welding. Both cylinders ship empty and are filled at a local welding gas supplier.

A small oxy-acetylene set handles soldering, brazing, heating, light welding, and thin-metal cutting. It suits jewelry work, HVAC brazing, auto repair, and hobby fabrication where a full-size rig is more than you need. The compact tanks make it portable enough to carry to the job.

You will need an oxy-acetylene torch handle with an oxygen regulator that fits the CGA540 valve and an acetylene regulator that fits the CGA200 valve. These are the standard connections for oxygen and MC acetylene cylinders, so most small torch kits match them. The set includes the cylinders only, not the torch or regulators.

Run time depends on your torch tip size and how continuously you work, but these small tanks are sized for short jobs rather than all-day production. A light brazing or jewelry session gets good use from a fill, while heavy cutting draws them down quickly. Watch both gauges, since oxygen is usually consumed faster than acetylene.

MC is a standard cylinder size code, and an MC acetylene tank is the smallest common portable acetylene cylinder at about 10 cubic feet. It pairs well with a small oxygen tank for a light, portable oxy-acetylene outfit. The MC size uses a CGA200 valve, the standard connection for small acetylene cylinders.

Yes, any welding gas supplier can fill the oxygen cylinder, and acetylene is usually handled through fill or exchange at the same supplier. Because you own these cylinders, you can refill rather than rent, though many suppliers exchange small acetylene tanks instead of filling them on the spot. Ask your local supplier how they handle MC acetylene.

No, both cylinders ship empty for transport safety, so they must be filled before use. Take them to a welding gas supplier for oxygen and acetylene, and confirm the acetylene is filled with the correct acetone base. Once filled and connected to a torch with the right regulators, the set is ready.

Yes, a small oxygen and acetylene set is a practical starting point for learning brazing, soldering, and light welding without a large investment. The portable tanks are easier to store and handle than full-size cylinders. As your work grows, you can step up to larger oxygen and acetylene tanks for longer run time.

Yes, both cylinders are new and carry current approvals: the acetylene tank is DOT and TC approved, and the oxygen tank is UN/ISO stamped and DOT approved, certified or hydro-tested within the last 12 months. New cylinders start the requalification clock fresh, so the next test is years away. A supplier reads the collar stamp before filling.

In an oxy-acetylene setup, acetylene is the fuel gas and oxygen supports combustion, and together they create a flame hot enough to weld, braze, and cut steel. The torch mixes the two gases, and you adjust each regulator to set the flame. That is why the two tanks are sold together as a matched set.
