The best gas soldering irons, compared.
Top pick: LEXIVON LX-770 kit – Highest score: 4.6 from 12,139 reviews, a flame lock, seven tips and a case at about £33.99. Best value: DOMINOX SI212 kit – Lowest-priced complete kit in the set at about £24.99, after the weaker POFET review pattern is set aside. Updated October 2026.
A gas soldering iron is a refillable butane tool that heats a soldering tip. On several of these amazon.co.uk listings it can also run as a small torch or a hot-air nozzle. You buy one when a mains lead is the problem: a car loom, a gate, heat-shrink outdoors, or a craft job away from a socket. None of the nine listings includes the butane, so the iron arrives empty. A fine circuit-board joint still belongs on an electric iron. Read an open-flame figure and an equivalent-watts line as mode-specific claims, and keep a clash between the title and the attribute visible. The [gas soldering iron buying guide](/hub/soldering-and-welding/gas-soldering-iron/sub/gas-soldering-iron-buying-guide) sets the order: fuel, tip versus flame, the job, then the lock.

Question 1 of 2
What is the job?
The LX-770 combines a refillable butane pen, seven tips, a flame lock and a carrying case for £33.99. Its amazon.co.uk rating of 4.6 from 12,139 reviews is by far the deepest review base in this comparison, which makes the positive pattern more useful than a high score from only a handful of buyers. The listing separates tip heat of up to 1,100 °F from open-flame heat of up to 2,400 °F, although a separate 1,300 °C attribute means you should still treat the figures as mode-specific rather than interchangeable. A claimed runtime of up to 75 minutes is practical for vehicle wiring and outdoor repairs where a mains lead gets in the way. The trigger ignition, stopper and lock make repeated use less fiddly, but the lock also means the lit tool must never be left unattended. Butane is not supplied, so the iron arrives empty and needs a compatible refill before first use.
Pros
Cons
Best for: Portable wiring, heat-shrink and general repairs where a socket is unavailable.
Less suitable: Fine circuit-board work that needs a set, visible tip temperature.
Specifications
Common questions
Does the LX-770 include butane?
No. The bullet says butane is not included. UK reviews also say the tank arrived empty.
Is there a flame lock and a case?
Yes. The bullet names a flame locking button, an ignition stopper, and a handy carrying case.
Which temperature is the soldering tip?
The bullet says up to 1100 °F with soldering tips and up to 2400 °F for the flame. The attribute maximum is 1300 °C. The listing does not reconcile those three figures.
The Dremel Versatip F0132000KF is another seven-accessory butane craft tool, but it must not be treated as the same specification as the F0132000JD. This listing states 35 W and an upper temperature of 482 °C, rather than the other ASIN's 1,200 °C attribute. Its 4.6 amazon.co.uk rating looks strong, although it comes from 93 reviews and only five UK review texts were available. One of those buyers found it effective for heat-shrink but too hot for soldering even at the minimum setting, which is a meaningful limit for delicate components. The integrated trigger and multi-tip box suit general craft and cable work, but there is no display to show the actual tip temperature. At £39.95 it is a reasonable specialist choice only if the included accessories matter more than precise thermal control.
Pros
Cons
Best for: Heat-shrink, pyrography and general craft work where several tips are useful.
Less suitable: Delicate soldering that needs a reliably low set temperature.
Specifications
Common questions
How is this Versatip different from F0132000JD?
This ASIN is F0132000KF at £39.95. The upper temperature rating is 482 °C and the wattage attribute is 35 watts. F0132000JD states 1200 °C and no wattage.
What did UK reviews say about soldering heat?
One United Kingdom review says it is great for heat-shrink and not so good for soldering because it gets too hot even on the minimum setting. Only five UK review texts were available.
Is a metal case included?
The included line says a sponge in a box. It does not name a metal case.
The LX-771 is the longer-running LEXIVON option, with a claimed two-hour runtime, an attachable stand and a hands-free flame lock. At £36.46 and 4.5 from 7,405 amazon.co.uk reviews, it sits close to the LX-770 but costs a little more for the stand and longer claimed use. The listing describes output as a 125 W equivalent and open-flame heat up to 2,400 °F, but it does not provide a separate soldering-tip temperature. That omission matters if you work on heat-sensitive pads rather than cable joints or heat-shrink. The stand is useful on a bench, while the lock reduces the need to hold the control during continuous heat. Butane is not included, and the carrying case appears in review evidence rather than the listing bullets, so buy on the confirmed stand rather than assuming every accessory shown is supplied.
Pros
Cons
Best for: Longer portable jobs and bench work where the stand is useful.
Less suitable: Temperature-sensitive electronics requiring precise control.
Specifications
Common questions
Does the LX-771 include butane?
No. The bullet says butane is not included.
Can it stand on the bench?
The bullet names an attachable base stand and a hands-free flame lock. A case is mentioned in UK reviews, not in the bullets.
What wattage does the listing state?
The item highlight says pro grade 125-watt equivalent. There is no separate wattage attribute.
The Dremel Versatip F0132000JD is a 96 g multi-tip tool aimed at soldering, hot-air work and craft tasks rather than one narrow repair. Its seven accessories, integrated ignition and boxed kit make it convenient when you want to switch between a soldering tip, shrinking and pyrography without carrying separate tools. The amazon.co.uk listing shows 4.5 from 559 reviews at £39.10, a credible result but with much less review depth than either LEXIVON. Its attribute gives an upper temperature of 1,200 °C without separating the operating modes; Dremel's UK information distinguishes lower tip and hot-air temperatures from that open-flame maximum. This is therefore not evidence that the soldering tip runs at 1,200 °C. Butane supply is not confirmed in the box list, so plan to source fuel separately. Choose it for accessory versatility, not for fine electronic control, because there is no temperature display.
Pros
Cons
Best for: Craft, pyrography, heat-shrink and varied portable jobs using several tips.
Less suitable: Fine PCB joints that need stable, visible temperature control.
Specifications
Common questions
What temperature does this Versatip listing state?
The upper temperature rating is 1200 °C. This listing does not split a tip temperature from a hot-air or open-flame figure.
Is butane in the box?
The bullets do not say. They name the tool, seven accessories, two wrenches, soldering tin, and a sponge in a box.
Is it the same specification as F0132000KF?
No. This ASIN is F0132000JD at £39.10 with an upper rating of 1200 °C and no wattage line. F0132000KF is a different ASIN.
The Iroda Solderpro 110K promises the longest portable sessions in this set, with a title claiming 100 minutes and a bullet claiming 115 minutes. It also includes piezo ignition, a case, several working tips and a heat blower, which would suit a mobile kit if the specification were clear. It is not clear: the title says butane and 30–125 W, a bullet says 30–165 W, and the power-source attribute says battery powered at 165 W. The listing also has only six amazon.co.uk reviews behind its 4.0 rating, too little evidence to resolve those clashes through owner experience. At £70.30 it costs roughly twice as much as several better-supported tools here. Buy only after confirming the exact model and fuel specification with the seller; otherwise the long-runtime claim does not justify the uncertainty.
Pros
Cons
Best for: Long portable sessions only after the exact specification is confirmed.
Less suitable: Buyers who need an unambiguous specification or proven review history.
Specifications
Common questions
Is the 110K battery-powered?
The power-source attribute says Battery Powered. The title and bullets say butane, and a bullet says butane is not shipped. The listing contains both.
Which wattage and runtime are stated?
The title says 30–125 W and 100 minutes. A bullet says 30–165 W and 115 minutes. The wattage attribute says 165 watts.
Does it include a case and butane?
The bullet names a sturdy case. It also says butane is not shipped. One of four UK reviews says the refill port leaked.
The Iroda Solderpro 50K packages a soldering tip, hot-air blower, hot knife and torch tip into a compact four-in-one kit. Its title states 30–70 W equivalent output and up to 40 minutes of runtime, while the attribute line gives 70 W and 450 °C. That makes it particularly relevant for portable heat-shrink, because a hot-air attachment is explicitly included rather than merely implied by a product image. The amazon.co.uk score of 3.9 from 742 reviews is middling, and UK texts include leaks, a melted jet and early failure as well as successful use. Flint ignition in the safety cap is less immediate than a built-in piezo trigger and gives you another component to keep track of. At £34.99 it is sensibly priced for the range of tips, but inspect the refill valve and flame behaviour before relying on it away from home.
Pros
Cons
Best for: Portable heat-shrink and mixed light-duty jobs needing several tip types.
Less suitable: Users who want piezo ignition or depend on the tool for daily work.
Specifications
Common questions
How does the Solderpro 50K light?
The included list names a safety cap with a stone ignition, which is a flint, not a piezo trigger in the handle.
What tips are in the kit?
Soldering tip, hot knife, hot air blower, and torch tip, plus solder and a sponge. A hot-air tip is in the included list.
Which wattage line should you read?
The title says 30–70 W and up to 40 minutes. The wattage attribute says 70 watts. The upper temperature rating is 450 °C.
The DOMINOX SI212 offers seven tips, self-ignition and a lock for £24.99, making it the lowest-priced complete kit here that avoids the POFET's especially weak review pattern. Unscrewing the front exposes an open flame, so it can cover soldering, hot-air-style work and small torch jobs rather than acting as a single-purpose iron. Its amazon.co.uk rating is a modest 3.7 from 113 reviews, and reports of failed sparking or flame escaping at the side make inspection at first use essential. The 15 W attribute and upper rating of 896 °F do not explain how heat differs between the soldering tip and flame modes. A case appears in reviews rather than in the confirmed attributes, and butane is not supplied. It is the best-value option only for an occasional user prepared to check ignition and shut-off carefully; frequent or critical work justifies spending more.
Pros
Cons
Best for: Occasional heat-shrink, craft and general repair work on a limited budget.
Less suitable: Frequent professional use or any tool showing a leak or persistent side flame.
Specifications
Common questions
Does the DOMINOX kit include butane?
No. The title says butane gas is not included.
Why does the wattage say 15 W?
The wattage attribute says 15 watts. The bullets describe an adjustable butane flame and do not state a wattage. Both lines are on the listing.
Does it lock on?
Yes. After ignition, the safety lock can hold the flame on so the button does not have to stay pressed.
The Iroda PRO15 uses a multi-angle pistol grip and ten-tip set, a format that may feel steadier than a slim pen when you work on larger cable joints. A safety switch beneath the trigger is intended to prevent accidental ignition in a tool bag, and the listing states 130 W with an upper temperature of 500 °C. However, its amazon.co.uk rating is only 3.6 from 82 reviews. More importantly, all three available UK texts in the source are negative, reporting a tool that did not work, heated very slowly or appeared pre-owned, with one complaint about no seller response. The £33.83 price is close to substantially better-supported kits, so the extra tips do not make it compelling. Consider the grip only if you specifically need the pistol shape and can test ignition, heat-up and shut-off immediately on arrival.
Pros
Cons
Best for: Buyers who specifically prefer a pistol grip and can test the unit promptly.
Less suitable: Anyone prioritising established reliability or seller support.
Specifications
Common questions
How do you stop the PRO15 lighting in a tool bag?
The bullet says a safety switch under the trigger means it cannot be ignited by accident.
What do the UK reviews say?
Three United Kingdom review texts were available. They say it does not work, the seller did not reply, or it takes ages to heat up. One buyer says the unit was pre-owned.
What wattage and temperature are on the attribute lines?
Wattage is 130 watts and the upper temperature rating is 500 °C. A separate tip-versus-flame split is not on the listing.
The POFET pocket pen costs only £8.99 and claims a 450 °C soldering tip, a 1,300 °C flame and 40 W output in a 30 g body. Those figures make it look attractive as an emergency tool, but the amazon.co.uk evidence is weak: 2.9 from 19 reviews, with three of the four available UK texts calling it dangerous, useless or non-working. The listing also fails to state the ignition method, flame lock, case or runtime. Its included-components field says USB even though the product is presented as a butane pen, adding another unresolved listing inconsistency. A low purchase price has little value if a gas tool will not light reliably or shut down predictably. Skip this one unless the listing and recent review pattern change materially, and stop using any unit that leaks or throws flame from the side.
Pros
Cons
Best for: No recommended use on the present listing evidence.
Less suitable: Any repair where reliable ignition, shut-off or heat control matters.
Specifications
Common questions
What temperatures does the POFET bullet state?
The bullet says flame temperature 1300 °C and soldering iron temperature 450 °C, both adjustable. The attribute upper rating is 450 °C.
Does the listing say how it lights?
No. Ignition, a flame lock, and a case are not stated.
What do the UK reviews say?
Four United Kingdom review texts were available. One calls it good for DIY. Three say it is dangerous, does not work, or is useless. The star line is 2.9 from 19.
We compared nine gas soldering iron listings on amazon.co.uk, captured on 16 October 2026. The score is an editorial comparison score. It is not a laboratory flame test, and it does not treat an amazon.co.uk star rating as a safety result. Very small review samples receive less credit. Repeated reports of leaks, failed ignition, side flame or early failure reduce the score. Unresolved conflicts in fuel, wattage, runtime or temperature also reduce the score. A low price does not offset evidence that a gas tool may be unreliable. The top pick is the highest overall score. The best value is the strongest lower-priced complete kit after reliability and specification clarity. The weights below sum to 100.

Choose the job before the star rating. A car loom, outdoor heat-shrink and a craft tip are different from a fine pad that needs a set temperature. Then check fuel, which figure is the tip, and whether the listing argues with itself.
A gas soldering iron, for a UK shopper, is a refillable butane tool that heats a soldering tip. Several pens in this set also unscrew or swap to a small torch or a hot-air nozzle. People buy one when a mains lead is the problem: a car loom, a gate, heat-shrink outdoors, or a craft job away from a socket. The nine amazon.co.uk listings here run from about £8.99 to £70.30, and none of them includes the butane.
A gas soldering iron in this set is butane. A USB or battery pen is a different product, and the POFET included-components line that says USB does not turn that listing into a clear butane specification.
Open flame on maker pages sits near 1,200–1,300 °C. Soldering tips are often stated around 450–550 °C. Dremel’s UK page splits 550 °C at the tips, 680 °C hot air and 1,200 °C open flame. The two Versatip ASINs do not share one upper temperature.
Refill cold, wait about two minutes, point the tip away, and do not cap a hot tool. Stop if the iron leaks, throws flame from the side, or will not shut off. Gas pipe, fuel tanks, brake lines and house mains wiring belong with a professional.
The tool has to be butane, not a USB or battery pen picked up from the same search. The iron ships empty. The Cigarette Lighter Refill (Safety) Regulations 1999 stop the sale of a butane lighter-refill canister to anyone under 18. Open flame on maker pages sits near 1,200–1,300 °C. Soldering tips are often stated around 450–550 °C. Dremel’s UK information for the F0132000JD distinguishes 550 °C at the tips, 680 °C hot air and 1,200 °C open flame.
Piezo, a trigger and a flint cap are different ways to light the tool. A flint in a removable cap, as on the Iroda Solderpro 50K, is another part to keep. A flame lock helps two-handed work and is also how a lit tool gets left alone, so a locked flame is never left unattended. A stand, on the LX-771, matters on a bench. A case matters in a tool bag. If wattage, power source or upper temperature disagree inside one listing, both lines stay visible.
Three typical situations, each with a recommendation from this comparison.
You are soldering or shrinking wire on a vehicle, a gate or another job where a mains lead gets in the way. The LEXIVON LX-770 is about £33.99, with 4.6 from 12,139 reviews, a flame lock and a case. Skip it for a fine pad that needs a visible set temperature.
You want a seven-tip butane kit and you will check ignition and shut-off on the first use. The DOMINOX SI212 is about £24.99, with 3.7 from 113 reviews. It is a poor fit if the tool leaks, sparks unreliably, or you use it every day.
You want soldering, hot air and craft tips in one box, and you will not treat 1,200 °C as the solder setting. The Dremel Versatip F0132000JD is about £39.10, with 4.5 from 559 reviews. It has no temperature display.
For portable wiring and heat-shrink, the top pick is the LEXIVON LX-770 at about £33.99: 4.6 from 12,139 amazon.co.uk reviews, a flame lock, seven tips and a case. For an occasional kit at a lower shelf price, the best value is the DOMINOX SI212 at about £24.99, and only if you check ignition and shut-off. The £8.99 POFET is not that pick: 2.9 from 19 reviews, with UK texts that call it dangerous or non-working. None of these scores is a flame test, and none of the tanks includes butane.
