Multipurpose soldering and hot-air kit
Blazer SI-100CR Excalibur Review
The Blazer SI-100CR Excalibur is a cordless butane kit that combines soldering, hot-air, hot-knife, reflector, and pinpoint-flame functions. Its five interchangeable tips and hard case make it convenient for portable repair work, but inconsistent availability and limited manufacturer documentation make it less straightforward to recommend than better-supported current models.
Quick verdict
A compact all-in-one kit with an important availability caveat
The Excalibur gives mobile users a soldering iron, hot-air blower, hot knife, reflector, and torch flame in one organized case. Piezo ignition, cordless operation, and the child-resistant trigger are practical strengths. Buy it only when the listing is clearly new, complete, and returnable because Blazer’s catalog link no longer opens a dedicated product page and replacement support is less visible than it is for leading alternatives.
Best for
- Portable soldering, heat-shrink, and small repair jobs
- Hobbyists and technicians who want several heat functions in one case
- Buyers who find a complete new kit from a reputable seller
Not ideal for
- Fine electronics requiring regulated tip temperature
- Buyers who prioritize current replacement-part support
- Anyone considering an incomplete used kit or unclear marketplace listing

What We Evaluated
This review examines the Excalibur’s catalog status, current retailer records, existing specifications, ignition and safety controls, five-tip accessory system, intended applications, fuel needs, and fit among modern cordless soldering tools.
How this review was prepared: This update uses Blazer’s current catalog, the site’s existing review, and current retailer specifications. The manufacturer detail page is no longer available, so unverified runtime, warranty, and precision-temperature claims are intentionally excluded. This review does not claim independent laboratory or long-term hands-on testing.
Design, Controls, and Portability
The Excalibur is a wand-style tool approximately nine inches long. It uses a refillable internal tank, piezoelectric self-ignition, an anti-flare design, and a child-resistant trigger, so no separate striker or electrical connection is needed.
The hard-shell case organizes the torch body, tips, wrench, sponge, and solder. That compact package is useful for field service and hobby work, although an incomplete used kit loses much of the model’s appeal.
The design is built around interchangeable functions rather than calibrated temperature control. Gas pressure, fuel level, tip choice, and technique influence the delivered heat, so it cannot match a modern regulated bench station for repeatable electronics work.
Heating Performance and Applications
Retailer specifications list a maximum open-flame temperature of about 2,500°F. That figure describes the flame, not the working temperature of every soldering or hot-air tip, and should not be used as a precision setting.
Soldering and electrical repair
The chisel and diagonal tips suit common wire, connector, jewelry, maintenance, and small repair work away from an outlet. For fine-pitch, static-sensitive, or production electronics, use a grounded temperature-controlled station.
Hot air and reflector work
The hot-air blower and reflector make the kit useful for heat-shrink tubing, adhesives, and localized flameless heating. Use appropriate ventilation and follow the temperature limits of the material being heated.
Hot knife and open flame
The hot knife adds cutting and shaping capability for suitable materials, while the direct flame handles pinpoint heating. The knife is best treated as a light-duty accessory rather than a replacement for a dedicated hot-knife system.
Included Tips and Case
The SI-100CR kit is commonly listed with five interchangeable tips: a reflector, hot-air blower, hot knife, 3.5 mm chisel, and 3.0 mm diagonal soldering tip.
Typical packages also include a wrench, cleaning sponge, tube of 60/40 solder, and molded hard-shell case. Current marketplace listings can differ, so compare the product photographs and included-items list before ordering.
Because replacement-tip visibility is limited on Blazer’s current site, buyers should confirm that required consumable tips are available before committing to the platform. A complete new kit is safer than an incomplete secondhand tool.
Fuel, Runtime, and Maintenance
Current records consistently list a seven-gram internal butane capacity, but dependable manufacturer runtime data is no longer available. Expect operating time to change with gas setting, tip, fuel level, ambient temperature, and duty cycle.
Use compatible butane and follow the instructions supplied with the actual tool. Our guide to choosing butane fuel explains compatibility and purity claims, while the refill guide covers the general safety sequence.
Keep the burner and air openings clean, protect tips from impact, and allow heated components to cool before changing attachments or closing the case. Stop using the tool if the tank, valve, ignition, or seals are damaged or leaking; see the troubleshooting guide for safe preliminary checks.
Pros and Cons
Pros
- Soldering, hot-air, hot-knife, reflector, and torch functions
- Five interchangeable tips
- Piezoelectric self-ignition
- Cordless anti-flare design
- Child-resistant trigger
- Compact hard-shell case
- Useful for mobile repair and hobby work
Cons
- Manufacturer detail page no longer works
- Availability and bundle condition vary
- Replacement-tip support is difficult to verify
- No closed-loop temperature regulation
- No dependable current runtime or warranty documentation
- Hot knife is best suited to light-duty work
Owner Feedback and Reliability
The existing Butane Torch Shop article emphasizes portability, quick ignition, solid construction, and easy switching between the hot-air and soldering functions. It also notes that the hot knife is better suited to fine work than demanding cutting.
Those themes are plausible for the design, but current long-term support is harder to verify than it is for the Master Appliance and Portasol platforms. Test ignition, gas adjustment, every included tip, and the case during the seller’s return period, and retain proof of purchase.
How It Compares
| Decision | Blazer Excalibur | Master UT-100SI | Power Probe PPSK |
|---|---|---|---|
| Best fit | Buyers finding a complete multipurpose kit | Professional field service and heat shrink | Automotive buyers wanting a full kit |
| Core advantage | Five functions in a compact case | Current manufacturer parts support | Organized automotive-oriented accessories |
| Main tradeoff | Availability and support uncertainty | Premium price and basic standard bundle | Bulkier case and kit |
Choose the Excalibur only when you find a complete new kit with clear return terms. Choose the Master Appliance UT-100SI when current parts support and professional field service matter most, or the Power Probe PPSK for an automotive-oriented kit. The Dremel VersaTip is the more approachable crafts and DIY option. Browse the soldering tools hub for the full comparison.
Is the Blazer SI-100CR Excalibur Worth It?
Potentially—but only at the right price from a reputable seller. A complete Excalibur kit remains a versatile portable package for soldering, hot air, heat shrink, hot-knife work, and pinpoint flame tasks.
For most buyers, the Master Appliance UT-100SI, Portasol Super Pro 125, or Power Probe PPSK is the safer long-term purchase because current documentation and replacement support are easier to verify. Avoid incomplete used kits and listings that do not clearly show all five tips.
Frequently Asked Questions
Is the Blazer SI-100CR Excalibur discontinued?
Blazer’s current catalog still names the Excalibur, but its old product-detail link redirects to the company homepage and availability varies by retailer. Treat it as a limited-availability model and verify that the listing is complete and returnable.
What tips come with the Excalibur?
The commonly listed kit includes a reflector, hot-air blower, hot knife, 3.5 mm chisel, and 3.0 mm diagonal soldering tip.
How hot does the Excalibur get?
Current retailer records list a maximum open-flame temperature of approximately 2,500°F. That is not the operating temperature of every soldering or hot-air tip.
Can the SI-100CR solder electronics?
It can handle general soldering, but it lacks closed-loop temperature regulation. Use a grounded temperature-controlled station for delicate, static-sensitive, or production electronics.
What fuel does the Excalibur use?
It uses refillable butane. Follow the instructions supplied with the tool and review our butane fuel guide before filling.
Should I buy a used Excalibur kit?
Only if the ignition and gas controls work, the tank does not leak, and all required tips are present. Limited replacement-support visibility makes incomplete used kits a poor value.
