Ridgid 18V Cordless Heat Gun Takes Butane Out Of The Equation
A heat gun is one of those tools that when you need it, there many reasonable substitutes. The R860435B Ridgid 18V Cordless Heat Gun hits the market with some upgrades over the previous butane-fueled model (R860434). Should you upgrade? Letโs take a closer look.

Ridgid 18V Cordless Heat Gun Performance

For many people, a corded heat gun works well, but the hassle of pulling out the cord and locating an outlet makes cordless convenience awfully attractive.
For the R860435B version, the Ridgid 18V cordless heat gun moves away from butane and instead relies solely on its 18V battery system to produce heat. While there are runtime consequences, itโs a drastic improvement for the simple fact that you donโt have to keep extra butane on hand.
Once you pull the trigger, the heat gun reaches working temperature in about ten seconds. The max heat output you can get is 900ยฐ F and 1100 BTUโs. This is 200ยฐ less than its predecessor and about 100ยฐ less than some of its competitors. If that heat level is still enough for your application, the convenience is completely worth it. Unlike the previous model, the R860435 does not have a temperature control dial.

Heat generation takes a lot of power, which is why Ridgidโs original design used a battery to run the fan and butane to produce heat. Using a 4.0Ah Max Output battery, we were able to run continuously for 14 minutes and 50 seconds. Considering the 15 minutes of butane capacity the previous model holds, thatโs effectively a wash. Better yet, itโs higher than what most other cordless gas-free heat guns are getting.

Ergnomics

As far as heat guns go, the Ridgid R860435 is reasonably compact. From end to end it measures 6.25 inches and it stands just over 7 inches tall without a battery. As far as weight goes, it only weighs 3 pounds with a Ridgid 4.0Ah Max Output battery.
This heat gun features a pistol grip design similar to Ridgidโs drills and impact drivers. The grip has a textured rubber overmold that easily channels sweat and provides a secure hold. As we expect, itโs bottom-heavy and thatโs a good thing for hands-free use.
Controls

The trigger features a safety switch to help prevent accidental activation during transport. Thereโs also a lock-on switch to use for hands-free heating. The tool is stable standing on its battery or pointing nose-up, opening up plenty of options.

The Bottom Line
While the Ridgid 18V cordless heat gun dropped down from the max temperature of the previous butane-fueled model, weโre impressed that the runtime is effectively the same. Unless you really need temps over 1000ยฐ F, we see no reason for Ridgid users to look to other platforms for their cordless heat guns.
