- Hobbyists and jewelry crafters who want adjustable heat in a compact kit.
- Field repair users who value quick ignition, light weight, and easy toolbox storage.
Skip If
- You want a corded soldering station with exact digital temperature control.
- You are not comfortable storing, refilling, or using butane tools.
- You need a tool for heavy fabrication, structural metalwork, or true welding jobs.
Key Features of the BLUEFIRE MRT-1117K
The BLUEFIRE MRT-1117K focuses on three practical strengths: cord-free use, adjustable heat, and multiple accessory options. Those features matter most when you need one compact tool for several light-duty tasks.
Portable Cordless Design
The 4-ounce weight helps reduce hand fatigue during short soldering sessions and small craft jobs. Its 8.27-inch length also makes it easier to pack than a larger station with a cord, stand, and power supply.
This design works best when portability matters more than bench-top precision. You can keep it in a repair kit, craft drawer, or small toolbox, but you should let it cool fully before storage.
Piezo Self-Ignition
The piezo self-ignition system helps you light the tool without a separate match or lighter. That can save time during quick repairs, especially when you only need a short heating session.
As with any ignition system, you still need to check the tool position, nearby materials, and ventilation before lighting it. Quick ignition is convenient, but it does not remove normal flame safety steps.
Adjustable Temperature Control
The article lists adjustable heat up to 1300℃, giving the MRT-1117K a wide working range for a compact butane tool. That flexibility helps when moving from soldering to heat shrink tubing or other small heat tasks.
The limitation is control style. A butane tool can give you heat flexibility, but it usually does not feel as exact as a digital soldering station that holds a set temperature on a display.
Performance and Usability
The BLUEFIRE MRT-1117K is built for users who care about fast setup and portability. The combination of a refillable butane system, self-ignition, and compact size makes it useful for small jobs that do not justify setting up a full station.
For soldering, the adjustable heat helps you match the task more closely than a fixed-output tool. For heat shrink tubing, the torch-style heat can be helpful, but you need to keep the flame moving to avoid scorching insulation or nearby surfaces.
Pro Tip: Start with a lower heat setting when working near wires, plastic, or heat shrink tubing. Increase heat only as needed, and test on scrap material when possible.
Accessory Kit and Versatility
The 9-piece accessory kit is one of the stronger reasons to consider this model. The article describes a butane torch, multiple tips, a sharp knife, a heat deflector, and additional kit pieces that help you adapt the tool to different tasks.
For buyers, that means you are not limited to one basic soldering point. You can choose a tip or attachment that better matches electronics work, heat shrink tubing, jewelry crafting, or small DIY repair tasks.
The accessory kit also adds a learning curve. You need to understand which tip fits each job, how hot the work area gets, and when to let parts cool before changing attachments.
How It Performs in Real Use
For Electronics Repairs
For small electronics repairs, the cordless design helps when the workpiece is not near an outlet. The tool is better suited to quick soldering tasks than long bench sessions that need exact, repeatable temperature control.
For Heat Shrink Tubing
The adjustable heat and torch-style capability can help with heat shrink tubing on wiring projects. Use controlled movement and avoid holding the heat in one spot, since too much direct heat can damage insulation.
For Jewelry and Craft Work
The compact body and accessory options make the MRT-1117K practical for small craft and jewelry tasks. It works best for detail-oriented heat application, not large pieces that need sustained high heat over a wide area.
For Field and Travel Repair Kits
The 4-ounce weight and 8.27-inch size make it easy to pack for mobile repairs. Just check fuel rules before travel, keep the tool protected from impact, and store it only after it has fully cooled.
How to Use It Correctly
- Read the product instructions before first use, especially the refill, lighting, cooling, and tip-changing steps.
- Use butane only, since the article states other fuel types are not compatible with this soldering iron.
- Refill with the unit turned upside down, aligning the nozzle carefully and pressing down firmly.
- Let the tool cool before changing tips, storing it, or placing it near fabric, paper, plastic, or other flammable surfaces.
- Keep your work area ventilated, especially during indoor soldering or heat-shrink tasks.
Safety and Fuel Notes
Because this is a butane-powered tool, safety matters more than it does with a simple low-power plug-in iron. Use it in a ventilated area, keep it away from flammable materials, and avoid leaving it unattended while hot.
The article states that the tool is designed for butane and should not be used with other fuel types. That limitation protects performance and safety, so do not experiment with alternate fuels.
For indoor use, ventilation is the key concern. You should also work on a heat-safe surface and keep children, pets, and loose materials away from the active tool.

Is It Worth the Price?
The BLUEFIRE MRT-1117K looks like a strong value for the price if you want one compact butane tool for soldering, heat shrink tubing, small craft work, and portable repairs. You get the most value from it when cordless use matters more than bench-top precision.
It is not the best fit if you mainly work at a desk and need a stable, digitally controlled soldering station. In that case, a corded station may feel easier to control during long sessions.
How It Compares to Alternatives
Compared with a corded electric soldering station, the BLUEFIRE MRT-1117K gives you more portability and faster setup away from outlets. The tradeoff is less precise temperature control and the need to manage butane fuel.
Compared with a larger butane torch, this kit is easier to pack and better suited to detailed soldering, heat shrink tubing, and craft work. A larger torch may be better for broader heat coverage, but it will not feel as practical for small repair jobs.
