The pages that follow explain a number of basicprocesses. The various tips are of interest toprofessionals and tradesmen. Always followbasic safety procedures.
For your safety
Fresh airis important when working with hot air. Softeningup paint may release solvents, solderingproduces vapors from the additives used, andvapors are also generated when welding plastic.This is why you should always work outdoors orwith the window open if work has to be done insmall rooms.
Working in the presence of waterwith electrical power tools is dangerous. Whenusing a heat gun, never work above or next touncovered water.
Testingis the magic word when it comes toexperimenting with hot air. Therefore alwayscarry out a trial run first before attempting anynew application. Check the airflow rate,temperature and compatibility of the hot air withthe material you intend to work on.
Safe OperationBe careful to avoid personal injury. Air heated toover 200°F (100°C) damages hair and injuresskin. A heat gun can reach up to 1300°F (700°C).Never direct heat gun at hair, skin or otherunprotected body parts.
Heat Guns in IndustryAerospace
In the aerospaceindustry temperature control iscritical in creating and repairingwire harness and soldering anddesoldering circuit boards forsatellites, radios and othercommunication devices.STEINEL heat guns with LOCtechnology and LCD displayprovide the precision and controlthese applications require.
Exterior composite work andfabricating aircraft interior panelsare demanding applicationswhere a durable tool isnecessary. STEINEL heat guns,tested to endure up to five timeslonger than other heat guns,provide the long lifeexpected bydiscriminatingprofessionals.
ElectronicsDesoldering circuit boards is a jobthat requires precise temperaturecoupled with the ability to finelycontrol the stream of hot air.STEINEL heat guns offer the
ability to specifically selecttemperature in 10° incrementsas well as the ability to controlairflow. The variety of STEINELreduction nozzles enables theuser to control the stream of
hot air in the mostsensitive ofsituations.

This is how it's done
350 – 500°F (175 – 250°C)
Wire HarnessingThe automotive, electronics and aerospace industries use heat gunsin the manufacture of wire harnesses. This is done by placing wirebundles into the appropriate sized tubing and shrinking it down tohold the wires in place. Applying hot air at 350 – 500°F (175 – 250°C)will shrink the tube to the correct size. Precise and consistenttemperature is crucial in this process to prevent damage to the wiresand to prevent scorching or blistering the shrink tubing.
The 75mm and 39mm reflector nozzles are a popular choice for thisapplication because they direct hot air around a larger diameterbundle of wires. Heat guns are also used in wire harness shops tocauterize the ends of wire harness braids.
9
350 – 500°F (175 – 250°C)
Heat Shrink, Connectors and Solder SleevesIn the electronics and MRO industries heat guns are often used tomake and protect wire connections. This is done by sliding a heatshrink tube of the appropriate diameter over the connection and thenshrinking it on using hot air at 350 – 500°F (175 – 250°C) and areflector nozzle. STEINEL heat guns offer precise, even heat allowingthe user to effectively control temperature output and preventscorching or blistering the tubes and sleeves. The 9mm reducer isrecommended for repairs where a smaller diameter shrink tube isbeing used.
Solder sleeves with an integrated solder ring or crimpconnection are available to ensure that a reliable electricalconnection is made. They are also available with anadhesive coating on the inside for watertight connections.The 14mm reflector fit solders sleeves well, making it agreat choice for this application.
Similarly the automotive andaerospace industries use heatshrink and solder sleeves forrepairing wire harness.

This is how it's done
250 – 325°F (120 – 165°C)
Activating and Deactivating AdhesivesAlmost any type of adhesive can be loosened using a heat gun. In theautobody repair industry aluminum vehicle frames cannot beexposed to flame; therefore, they must be dismantled and repairedwith a heat gun. A heat gun is used to loosen the adhesive at thejoints allowing them to be separated. Simply direct the hot air wherethe joint is glued. The adhesive will soften and can then be pulledapart without causing further frame damage.
Decals, stone guards, window tinting and stickers can easily beremoved from surfaces without the risk of damage. Hot air will leavenothing sticking to the original surface. Direct the stream of hot air atthe area you would like to remove and when the adhesive softenssimply pull the material back.
In the aviation industry heat guns are used for exterior compositework. Seams are sealed by layering carbon fiber mesh over seams
and heating them with hot air to fusethem together until the seam isfilled. Heat guns are also used tofabricate aircraft interiors. Fiberglass composite is layered over

250 – 325°F (120 – 165°C)
jigs to create the desired shape for each part of the aircraft’s interior.Heat guns are used to adhere each individual layer together until theyreach the desired thickness for the specific part.
The renovation and remodeling industries use heat guns forremoving glued-on coverings, building materials, wallpaper andflooring. This is accomplished by heating up the adhesive and simplyscraping off the material. Attach a spreader nozzle and direct the hotair between covering and the substrate layer. Joint sealingmaterials are also easy to remove with the help of hot air.
In the flooring industry tile adhesive is stubborn anddifficult to get off. Heat softens the adhesive whichcan then be removed with a scraper and cloth.
Working adhesives with hot air is always anadvantage when you want to bond orrelease large areas. Therecommended temperature for thisis 250 – 325°F (120 – 165°C).

This is how it's done
450 – 725°F (230 – 385°C)
Plastic WeldingThe flooring industry uses heat guns to weld plasticized PVC inflooring joints and seams. Plastic welding is also used in theautomotive repair, MRO and orthotics and prosthetics industries torepair plastics.
The materials being welded must always be the same composition,the type of plastic must be identified before welding the two partstogether (see table for distinguishing characteristics). Select weldingrod of the appropriate material. Clamp work pieces in position. Clean,degrease and, if necessary, bevel the seam. Now heat the seam withhot air to 450 – 725°F (230 – 385°C) and offer up the welding rod via awelding nozzle. For a strong weld, the work piece and welding rodmust turn to a "doughy" consistency. The seam can be validatedusing a pull test which, if acceptable, produces stress whitening.

MedicalMedical plastics used in orthotics and prosthetics can be shapedand welded using a heat gun. Unlike open flame there is more controlover temperature output and less chance of scorching theseexpensive devices. To achieve a custom fit the materials can beheated with hot air ranging from 250 – 350°F (120 – 175°C) thenshaped and smoothed. In the case of foam materials temperaturescan be as low as 160°F (70°C).
Dental labs use heat guns to reshape, weld and repair dentures. It isbest to consult with the material manufacturer for the workable heatranges of these materials.
In optical labs eye glasses often need to be adjusted tofit. Frame heaters are too small for large eye glassframes, preventing uniform heating. A heat gun set up
as a bunsen burner and with a reflectornozzle will heat them evenly.
250 – 350°F (120 – 175°C)
15
325 – 425°F (165 – 275°C)
Shaping PlasticsThe flooring and MRO industries use heat guns to make plasticsheets, pipes and rods flexible without leaving burn marks. Plasticsheets for making containers are worked at 325 – 425°F (165 – 275°C)depending on material type. Folded edges are created by heating thework piece with a surface nozzle. The heated material then can bebent with ease.
Pipe and rod are evenly heated all theway around using a reflector nozzle.Once it has been heated it is easilyshaped or bent. Holding the piece inthe chosen position until cool ensuresit keeps the desired shape. A coil orsand filling helps prevent pipe kinking.
This is how it's done
775 - 1250°F (415 - 675°C)
RoofingHeat guns are used in the roofing industry to lap weld difficult areassuch as near vents and edges. To lap weld PVC a temperature ofapproximately 775 - 875°F (415 - 470°C) is delivered with a angled slitnozzle placed between overlapping sheets of PVC material until thesurface becomes soft and begins to stick together. Pressure is appliedwith a silicone seam roller on the top of the PVC to ensure the twopieces of material adhere securely.
Hypalon, modified bitumen and TPO are worked at highertemperature ranges. Temperature requirements for roofing materialsvary. Consult the material manufacturer for specific temperatureranges.

Tarps, Liners and Industrial Fabric WeldingPlastic tarpaulins in the trucking & transport and tent & awningindustries as well as coated textiles in the marine industry can bereliably welded using heat guns. This is done by overlapping twolayers of tarp or sheeting by approximately 3/4 – 1 1/2 in. (2 – 4 cm)and holding the tarps taut. Then using a slit nozzle, hot air rangingfrom 625 – 725°F (330 – 385°C) is blown between the overlap. Thematerial turns soft within a matter of seconds and is firmly pressedtogether with a feed roller. To test your work tear the welded seamapart with force at one end or on a sample piece. If stress whiteningoccurs in the material, the seam is satisfactory. Otherwise,temperature needs to be increased or speed decreased.
Common uses for these types of processes are to weld plasticsheeting together to create pond liners or to create and repair tarpsfor marine and transport coverings, tents and awnings.

325 – 425°F (165 – 275°C)
ConstructionThere are numerous ways heat guns are useful in the constructionindustry. For example, in cold temperatures vinyl siding will crackwhen you try to cut it or work with it. To prevent wasting materials andallow siding contractors to work through the winter in colder areas, aheat gun and spreader nozzle are used to quickly warm each piece ofvinyl siding before it is cut. This effectively prevents the material fromcracking. A temperature range of 325 – 425°F (165 – 275°C) worksbest for this type of application.
Hot air is also useful in plumbing for fitting pipes. Simply heat thehose or pipe end with hot air and push it on. As it cools it contracts tocreate a tighter connection than could otherwise be achieved.

450 - 750°F (230 - 400°C)
Vinyl and Leather RepairVinyl and leather repair is common in the automotive industry. Heatguns are used in the process of mending tears and removing wrinklesin both of these materials. Tears are first cleaned of any stray threadsand covered in a compound that matches in color to the originalsurface. Next it is covered with a textured clothmatching the original texture of the material.Finally, heat is applied ranging from 450 - 750°F(230 - 400°C) to set and dry the compound.
The 14mm and 20mm reducer nozzles allow theuser to aim the hot air directly at the area that isbeing repaired, speeding up the curing process.
Wrinkles in leather and vinyl upholstery are alsoeasily removed by applying heat.

This is how it's done
350 – 1200°F (175 – 650°C)
Maintenance, Repair and OverhaulHeat gun use in the MRO industry is abundant. Stripping paint,loosening seized bolts and fitting metal components done attemperatures ranging from 900 - 1200°F (485 - 650°C), are examplesof applications where heat guns come in handy. Thawing frozen pipesis effectively accomplished by using a 39mm or 75mm reflector nozzledirecting heat at a temperature range of 750 - 1200°F (400 - 650°C)around the frozen pipe.
Working with plastics is another popular application for heatguns in this industry. Plastic welding can be accomplished
with a 9mm reducer, plastic welding tip and a temperatureranging from 450 - 750°F (230 - 400°C) depending on
the material type. (See chart onpg. 13) Plastic shaping isalso done at 450 - 750°F(230 - 400°C).
350 – 1200°F (175 – 650°C)
Working adhesives, like removing decals, is yet another way heatguns are utilized in the MRO industry. This is done at temperaturesranging from 450 - 750°F (230 - 400°C).
Drying and melting compounds is done at a temperature of 450 -750°F (230 - 400°C). At these temperatures wax can easily be meltedor softened. Industry professionals can also use the sametemperature and a 50mm or 75mm spreader nozzle to quickly dryputties, paints and other compounds.
Applying shrink tubing is another practical application for heat guns inthe MRO industry. Using the 9mm, 14mm, 39mm or the 75mmreflector nozzle and a temperaturerange of 350 – 500°F (175 – 250°C)shrink tubes and solderconnectors can easily be applied.
STEINEL’s Industrial and Multi-Purpose heat gun kits offer a widevariety of accessories that areideal for the MRO industry.

Soldering and DesolderingHeat guns can be used in the electronics industry to desolderelectronic components from damaged circuit boards. Hot air, 750 –850°F (400 – 455°C) will loosen the solder joints allowing thecomponents to be removed. Concentrate the hot air on the solderjoint and remove the component with a special pair of pliers once thesolder melts.
The 9mm reducer delivers a preciseconcentrated stream of hot airthat is easy for a user tocontrol on the surface of acircuit board. This makesit the ideal accessory forthe delicate task ofdesoldering circuit boards.
23
PackagingThe packaging industry uses heat guns to touch-up shrink wrappingafter it has been through a heat shrink tunnel. This is done byapplying hot air, about 825 – 925°F (440 – 495°C), through a surfacenozzle to any area of a package that is not taut.
Foam inserts for packing electronics arecustomized to fit each product usingadhesives activated by heat guns. Thetemperature to activate these adhesivesrange from 300 – 600°F (150 –315°C). Thistemperature range allows for the adhesives toto sufficiently activate without scorching thefoam packing material.
The retail industry also uses heat guns to shrinkwrap gift baskets after they have been created
to seal in the contents andcreate a decorativewrapping for resale.
