Bossweld Oxygen Regulator Controls Gas Pressure

Here’s a detailed breakdown of Bossweld oxygen regulators — how they work, specifications, safety tips, and a few example models you can compare.

What Is a Bossweld Oxygen Regulator?

A gas regulator is a device that controls the pressure of a gas (in this case, oxygen) coming out of a cylinder (bottle), reducing it to a usable pressure for welding, cutting, or other gas-consuming equipment. A Bossweld oxygen regulator is a regulator made by the Bossweld brand, typically designed to meet Australian standards (AS 4267) for welding regulators.

Bossweld oxygen regulators are used in oxy-fuel setups, cutting torches, welding equipment, or any application where controlled oxygen pressure is required.

Key Specs & Features of Bossweld Oxygen Regulators

Based on product listings, manuals, and supplier information, here are typical features and technical specs to look for:

Feature	Typical Value / Description
Maximum Outlet / Working Pressure	1,000 kPa (≈ 10 bar) for many models
Maximum Inlet Pressure	Must not exceed the nominated pressure; often very high for cylinder pressure (e.g. up to 20,000 kPa)
Entry / Connection Style	Bottom entry, vertical, or side entry styles are available
Twin Gauges vs Single Gauge	Some models include two gauges: one to show cylinder (bottle) pressure, another for outlet pressure (flow)
Construction / Materials	No soldered joints (for safety), angled outlets, tough perspex / transparent lenses for gauges
Standards Compliance	Manufactured / tested to AS 4267 (Australian standard for gas regulators)
Safety & Warranty Notes	Bossweld warns that regulators should not be tampered with; warranty may be voided if used beyond specifications or repaired by non-authorized technicians.

From the Bossweld Oxygen Regulator Manual, some additional safe practices and guidelines:

• Bossweld regulators should only be used with gas they are intended for (i.e. oxygen regulator used only for oxygen)
• Do not test for leaks with a naked flame — always use safe methods (soapy water)
• Oil or grease must never contact the oxygen regulator, inlet, outlet, or associated fittings — oxygen can cause ignition of oils/greases
• Regulators should be replaced every 5 years per AS 4839 (gas supply standard) or earlier if damaged
• Use flashback arrestors both at the regulator and the torch in oxygen/fuel gas systems

Example Models: Bossweld Oxygen Regulators

Here are some Bossweld oxygen regulators you can view / compare. Each product is cited once with details from supplier listings:

• Bossweld Oxygen Regulator (400212 twin‑gauge, bottom‑entry) — A commonly referenced twin-gauge, bottom-entry oxygen regulator. Often listed in welding supply catalogs.
• Bossweld Oxygen Regulator Side Entry — Side-entry version (model 400205) — useful in setups where side connection is more convenient.
• Bossweld Oxygen Gas Regulator — General-purpose oxygen regulator (supplier listing) with specifications like 1,000 kPa outlet, no soldered joints.
• Bossweld Oxygen (400205) Side Entry — The side-entry model 400205 in a more visible listing (Beyond Tools).
• Bossweld Disposable Gas Bottle Regulator — A simpler / more economical regulator intended for disposable gas cylinders (may have lower durability).

From supplier sites:

• Bossweld Oxygen Vertical Entry Regulator (single-stage) with specifications: AS/NZS 4267 compliance, Type 10 inlet thread (5/8-18 UNF RH), max inlet 20,000 kPa, max outlet 1,000 kPa.

Choosing the Right Bossweld Oxygen Regulator

Here’s how to pick a model that fits your use case:

Use / Setup	Smart Choice	Why
Standard cylinder + torch setup	Twin gauge, bottom-entry version (e.g. 400212)	Gives both tank pressure and output pressure readings
Where space / alignment is tight	Side-entry version (e.g. 400205)	Easier to connect piping / hoses in constrained setups
Simple / economical use	Single gauge, vertical entry	Fewer complications, lower cost
Mobile / bench setups	Bottom-entry helps low center of gravity and more stable mount
Higher pressure / heavier duty	Ensure your setup (hoses, torch, fittings) can handle up to the regulator’s spec (1,000 kPa outlet)

Always ensure compatibility of threads (inlet / outlet), pressure ratings, and gas compatibility. Use oxygen regulators only for oxygen, never mix or interchange with acetylene or other gases.

Safety & Best Practices

• Always use flashback arrestors both on the regulator side and torch side when operating oxygen/fuel gas systems.
• Never allow oil or grease contact on oxygen regulators, fittings, or any part of the system. Clean hands, clean tools.
• Open cylinder valves slowly to prevent pressure shock.
• Inspect regulator components before use — gauges, seals, connections.
• Never exceed the pressure ratings stamped on the regulator.
• Replace regulators after 5 years, or earlier if damaged, in line with AS 4839.
• For leaks, use soap / detergent solution — never a flame.
• Do not disassemble or modify the regulator — repairs should be done by authorized agents only.
