BAK Rion 2 Hot Air Welding Tool with Metal Case

The BAK RiOn 2 is a professional-grade handheld hot air welding tool engineered in Switzerland for plastic welders who need reliable, consistent performance across demanding applications. Whether you're welding TPO and PVC membranes on a commercial roof, seaming thermoplastic flooring, repairing tarps, or fabricating plastic structures, this tool is built to perform in the field without compromise. Hot Air Tools stocks the BAK RiOn 2 with competitive pricing, includes a metal carry case with every unit, and backs every sale with in-house repair support, so you're covered long after the purchase. The RiOn 2 is a significant step forward from the original RiOn, delivering a set of upgrades that matter on the job site. A brushless motor extends service life and cuts maintenance costs. A built-in LED illuminates the weld seam for accuracy in low-light conditions. Automatic cooling protects the tool between runs. An ergonomic handle reduces hand fatigue during extended welding sessions. For professional plastic welders who put their tools to work every day, the BAK RiOn 2 is a top-tier choice.

BAK RiOn 2 Technical Specifications

Before committing to any hot air welder, professional plastic welders need to confirm the tool's specs align with their application and power supply. The BAK RiOn 2 runs on 120V or 230V at 50/60 Hz, drawing 1,600W of power. Temperature adjusts steplessly from 20°C to 650°C, and airflow reaches 250 l/min, well above many comparable tools in its class. The tool measures 100 x 360 mm with a 55 mm handle diameter, weighs 1.2 kg with cable, and produces 70 dB of operating noise. It carries CE certification. Hot Air Tools stocks both 120V and 230V versions, so you can order the right unit for your shop or job site without the guesswork.

Key Features of the BAK RiOn 2

The RiOn 2 is engineered for professionals who demand consistent, fatigue-free performance across full work days in roofing, flooring, and fabrication environments. Every design decision on this tool reflects the needs of welders who use their equipment hard. Key features include:

Brushless Motor

The brushless motor is one of the most meaningful upgrades the BAK RiOn 2 brings to the job site. Unlike traditional brush-motor designs, a brushless motor has fewer moving parts subject to wear, which means the tool runs longer between service intervals and holds up better under continuous use. When service is needed, the design makes repairs more straightforward and cost-effective than older motor configurations.

Hot Air Tools provides in-house repair support for the RiOn 2, so if your tool ever needs attention, you're not shipping it overseas or waiting weeks for a fix. The combination of a durable brushless motor and accessible repair service means this tool is built to stay in your kit for the long haul.

Ergonomic Handle and LED Light

The RiOn 2's slim, ergonomic handle is designed to reduce hand fatigue during the kind of extended welding runs that come with commercial roofing or large-scale flooring projects. When you're welding seam after seam over the course of a full work day, grip comfort is not a luxury, it's a performance factor. The built-in LED light addresses a practical problem that plastic welders know well: getting a clear view of the weld seam in low-light job site conditions. Whether you're working in a dim mechanical room or on a roof at dusk, the LED keeps the work visible and your welds accurate.

Stepless Temperature Control and High Airflow

The RiOn 2 offers stepless temperature adjustment from 20°C to 650°C, which gives plastic welders precise control over heat input for different thermoplastic materials and thicknesses. Welding TPO at the correct temperature window is a different task than working with PVC or HDPE sheet, and the ability to dial in exactly the right heat, rather than stepping between fixed presets, makes a real difference in weld quality and material integrity.

Paired with 250 l/min of airflow, the RiOn 2 distributes heat faster and more evenly than tools with lower output, including the widely used Leister Triac. The result is efficient, consistent welds with fewer cold spots and less rework.

Automatic Cooling and Rear-Integrated Air Filter

When a welding session wraps up, the RiOn 2's automatic cooling function runs the airflow to bring the tool's internal temperature down safely before shutdown. This protects the heating element and internal components from heat stress, extending the tool's service life over time.

The rear-integrated air filter draws in a clean air supply without the need for external attachments, keeping the tool compact and simple to operate on any job site. A clean air supply also contributes to consistent heating performance and protects internal components from contamination, a detail that matters on dusty roofing and fabrication sites.

BAK RiOn 2 Applications

The RiOn 2's combination of high airflow, stepless temperature control, and compatibility with a broad range of nozzle accessories makes it a practical choice for professional thermoplastic welding tasks across multiple industries. From commercial roofing to industrial plastic fabrication, this tool handles the full spectrum of work that plastic welders encounter in the field. Common applications include:

Roofing

The BAK RiOn 2 is one of the most capable handheld hot air welders available for commercial roofing work. It handles TPO and PVC membrane welding with the kind of precision and consistency that large-scale roofing projects demand. The 250 l/min airflow and stepless temperature control give roofing contractors the ability to work across varying membrane thicknesses and ambient conditions without losing weld quality.

The RiOn 2 is widely regarded as one of the best TPO heat guns on the market for hand welding, and its ergonomic handle makes it practical for the continuous seam welding that commercial flat roofing requires.

Flooring

For thermoplastic flooring seam welding, the BAK RiOn 2 delivers the control and comfort that floor installers need when working at ground level for extended periods. The slim ergonomic handle reduces strain during repetitive welding runs across large floor areas, and the built-in LED light improves visibility of the weld seam when working in low-light interior environments.

Precise temperature adjustment ensures clean, consistent welds in PVC and other thermoplastic flooring materials without scorching or delamination.

Plastic Fabrication and Tarps

The RiOn 2 is a versatile tool for general thermoplastic fabrication work, including welding PP, HDPE, PVC, and other thermoplastic sheets, as well as repairing tarps and banner material. Its wide temperature range and broad nozzle compatibility give fabricators flexibility across materials and joint configurations.

Whether you're building a chemical tank, repairing a tarpaulin, or joining plastic panels in a production environment, the RiOn 2 adapts to the job without requiring a tool change.
