Wagner Furno 300 and 500 have no display. The Furno 700 costs $55+. SolderStick shows the temperature climbing to its fixed 392°F (200°C) solder-seal setting at $39.99.
Best for Wiring Work
one fixed temperature — 392°F (200°C), the solder-seal working point — with a digital readout, plus connector-specific nozzles. The only sub-$40 heat gun built and set for heat shrink work, with nothing to dial wrong.
Best for Paint Stripping
wide adjustable range built for large-surface paint and adhesive work. Wagner's highest-priced model in the lineup. Costs 37% more than SolderStick.

No temperature display on either model — you flip a toggle and guess. Furno 500 just adds paint nozzles for $10 more.
You're looking at Wagner heat guns. Maybe you're on Home Depot's website right now, scrolling through the Furno 300, 500, and 700, trying to figure out which one you actually need.
Here's the part that trips up most buyers: the Furno 300 ($30) and the Furno 500 ($40) both run on the same two fixed heat settings. No display. You flip a toggle switch and read nothing. You can't see what temperature you're putting on the work.
The only difference between those two models? The Furno 500 comes with extra nozzles designed for paint stripping, adhesive removal, and crafting. If you're doing wire connector work, those nozzles are useless.
So you look at the Furno 700. Variable temperature. A readout. Finally, something that shows you the actual heat you're applying. But now you're at $55 or more. And it's still built as a paint stripping tool, not a precision instrument for heat shrink tubing.
That's the gap SolderStick fills — with one thing the base Wagners don't give you at any price: a display that shows you exactly where the heat is.
SolderStick's heat gun costs $39.99. At that price, you'd expect the same thing every other budget heat gun offers: a toggle, a guess, no display.
Instead, you get a digital readout and one fixed temperature — 392°F (200°C), the solder-seal working point. There's no dial to set and no setting to pick wrong. The gun is built to reach one temperature and the display shows you it climbing there in real time. A concentrator nozzle and a reflector nozzle come with it, both built specifically for directing heat onto solder seal connectors and heat shrink tubing.
That single fixed setting matters more than most people realize. A general-purpose heat gun gives you a range and leaves the right number up to you — too cool and the solder ring never flows, too hot and you char the insulation. SolderStick removes the guess entirely. The temperature is purpose-set at the exact point where the solder melts inside a heat shrink connector and the tubing shrinks around it at the same time.
No wrong setting to land on. That's the tool's whole purpose.

Heat guns from $29.99
Pairs with solder-seal connectors so a splice needs no soldering iron, flux, or separate heat-shrink kit.
Let's address the obvious: you can walk into Home Depot today and walk out with a Wagner Furno. That's a real advantage, and we're not going to pretend it isn't.
But consider what you're walking out with. If you grab the Furno 300 or 500 for $30-40, you're getting a heat gun with no display and no temperature set for solder seal work. You'll be estimating the heat every time you activate a solder seal connector. If the solder doesn't melt fully, you'll find out when the connection fails in the engine bay or behind the wall.
SolderStick ships with free worldwide delivery. You wait a few days. But when it arrives, you have a gun set to one temperature — 392°F (200°C), the solder-seal working point — a digital readout that shows you it getting there, a nozzle designed for the work you're doing, and a 30-day guarantee to return it if it doesn't perform.
A few days of shipping versus years of guessing at temperature. That's the trade.
SolderStick isn't a mystery brand. Three YouTube creators with over 1 million combined subscribers have featured their products:
These are people who solder connectors and shrink tubing for a living, on camera. They chose SolderStick's tools over the Wagner sitting at Home Depot.
The SolderStick product line has 5,000+ verified reviews at a 4.6 star average. The reviews come from people doing connector work, not paint stripping. That distinction matters because the feedback is from your exact use case.
Work excellent! Seal AND solder wires together! I just hit them for about 15 seconds.
Verified BuyerI had rats chew through some wiring on my car, used these and they work fantastic! Way easier than my old Wagner.
Verified BuyerWagner has been making heat guns since the 1970s. Known for paint strippers, wallpaper removers, and power sprayers. That's their expertise. When they build a heat gun, they build it for removing latex from drywall.
SolderStick's entire product line is solder seal connectors, heat shrink tubing, and the tools to activate them. Their heat gun exists because their customers needed one purpose-set for connector work, not adapted from a paint tool.
Known brand vs purpose-built brand. Different categories of trust.
True. The Furno 700 has an adjustable range and a temperature dial. If you're doing professional paint stripping AND connector work with the same tool, the Furno 700 is worth considering at $55.
But if your primary use is heat shrink connectors and tubing, a dial is one more thing to get wrong — set it too low and the solder never flows, too high and you scorch the insulation. SolderStick skips the dial: it's fixed at 392°F (200°C), the solder-seal working point, which is exactly the temperature heat shrink and solder seal work needs. You're not paying $15 more for a range you won't use.
You can. And if you need a heat gun in the next 30 minutes for a job that's already torn apart, grab the Wagner. Proximity wins in an emergency.
For anything planned, the math is different. SolderStick ships free, arrives in days, includes connector-specific nozzles, and comes with a 30-day money-back guarantee. If it's not the right tool, send it back. Wagner's Home Depot return means a drive back to the store.
Be honest about your primary use case. SolderStick is purpose-built for one job: heat shrink and solder seal connector work, at a fixed 392°F (200°C). That's its whole strength — no setting to get wrong. It is not a paint stripping tool, and we won't pretend it is.
If you're doing mostly paint stripping, broad-surface heating, or adhesive removal, the adjustable Furno 700 at $55 is the better fit — that's the work it's built for. If your real job is connectors and tubing, SolderStick does that one thing exactly right at $39.99.

Yes. It works with any heat shrink tubing or solder seal connector from any manufacturer. Its fixed 392°F (200°C) setting is the standard working point for activating polyolefin heat shrink and flowing the solder ring. It's not locked to SolderStick products.
Because solder seal connector work has one right temperature, not a range you should be hunting for. SolderStick is set at 392°F (200°C) — the point where the solder ring flows and the polyolefin tubing shrinks together. A digital readout shows it climbing there so you know the gun is ready. There's no dial to set too low (solder never melts) or too high (you scorch thin-gauge insulation). On a general heat gun with no display, every connection is a guess.
Free worldwide shipping. US orders typically arrive in 3-7 business days. Not same-day like Home Depot, but the 30-day money-back guarantee means zero risk if it doesn't meet your expectations.
No — and that's by design. SolderStick runs at one fixed temperature, 392°F (200°C), purpose-set for solder seal connectors and heat shrink tubing. It isn't a paint stripping tool and we won't pretend it is. If paint, adhesive removal, or broad-surface heating is your main job, an adjustable gun like the Wagner Furno 700 is the right buy. SolderStick does connector work, and only connector work, exactly right.
Keep the Wagner for paint work if that's its primary job. Add the SolderStick at $39.99 as your dedicated connector tool. Using a paint stripping gun for precision solder work is like using a sledgehammer for finish nails. Right tool, right job.
Try the SolderStick HeatGun for 30 days. Use it on your next wiring project. If it doesn't outperform the Wagner in your Home Depot cart, send it back for a full refund. No questions. No hassle. Free return shipping.
Wagner makes solid paint stripping tools. They've done it for decades, and for broad-surface heat work their adjustable guns earn their place. But when you need a heat gun for wire connectors, solder seals, and heat shrink tubing, an adjustable dial is just one more thing to set wrong.
SolderStick removes the guess: one fixed temperature — 392°F (200°C), the solder-seal working point — a digital readout that shows it climbing there, and purpose-built nozzles for $39.99. Wagner charges $55+ before you even get a display.
30-day guarantee. Free shipping. 5,000+ reviews from people doing the same work you are. If it doesn't outperform the Wagner sitting in your Home Depot cart, send it back.
