Sievert Pro 86 Cyclone Gas Blow Torch Kit – 3524 Cyclone Burner | Plumbing & Brazing
A complete Sievert Pro 86 kit built around the 3524 cyclone burner — designed for plumbers who are soldering and brazing continuously. The cyclone flame rotates around the pipe for even, all-round heat transfer. 3.1kW at 2 bar, soft soldering to 50mm, brazing to 18mm. 3486 handle, 4m hose and 0.5–4 bar propane regulator included.
The cyclone burner is the distinguishing feature of this kit — and the reason it is the preferred choice for plumbers doing repetitive soldering and brazing work. Where a standard flame heats the near side of a pipe first and conducts heat around to the far side, the cyclone burner's rotating flame wraps around the pipe simultaneously, giving even heat distribution across the full circumference without the need to move the torch. For continuous pipe soldering and brazing through a working day, that even, all-round heat transfer delivers faster, more consistent joints with less torch movement.
The 3486 handle is the standard Pro 86 ergonomic handle — interchangeable with the full range of Sievert Pro 86 burners for versatility across different applications. The 0.5–4 bar adjustable propane regulator gives precise output control across the full working range.

Why Buy the Cyclone Kit Over a Standard Burner Kit?
The rotating flame is the correct tool for pipe work — A standard flame heats one side of the pipe at a time; the cyclone wraps heat around the full circumference simultaneously. For plumbers soldering joint after joint through a working day, that difference in heat distribution means faster, more consistent joints and less repositioning of the torch at each joint.
Pro 86 handle works across the full burner range — The 3486 handle can accept any Sievert Pro 86 burner. If the cyclone isn't the right tool for a particular job, swapping to a different burner is straightforward without replacing the handle, hose or regulator.
The plumber's choice for continuous soldering and brazing. Order today and work with the cyclone burner's rotating flame for faster, more consistent pipe joints.
