A powder flame spray gun feeds metallic, ceramic, or alloy powder into an oxy-fuel flame, melts it, and sprays it onto a prepared part. The result is a dense layer such as silver-grey self-fluxing nickel alloy, dark grey tungsten carbide, white alumina ceramic, or golden bronze, built to resist wear, rust, heat, and oxidation. Airo Shot Blast Equipments is a manufacturer, supplier, and exporter in Jodhpur, India. We build the powder flame spray gun as a ready-to-use kit with hoses, flowmeter, regulators, and mounting stand.
What Is a Powder Flame Spray Gun?
A powder flame spray gun is a handheld thermal spray tool. Powder drops into an oxy-fuel flame, softens or melts, and compressed air carries the particles onto the workpiece where they bond and build up a coating. It is one of the lowest-cost ways to apply hard alloys, ceramics, and carbides, and it sprays both ferrous and non-ferrous parts.
Unlike a wire gun, which melts a metal wire, a powder gun can use many more materials because any metal, alloy, or ceramic available as powder can be sprayed.
How Does a Powder Flame Spray Gun Work?
- Blast the surface: Clean the part to a grey, rough, near-white finish with a sandblasting or shot blasting machine.
- Light the flame: Oxygen and fuel gas burn at the nozzle.
- Feed the powder: A built-in canister, or a separate Powder Feeder, meters powder into the flame.
- Melt and propel: The powder heats up, and compressed air drives it toward the part.
- Build the coating: The particles flatten and bond to the surface, giving 50–500 µm per spray setup.
- Finish: Depending on the powder, the coating can be fused, ground, or machined.

Short answer: Choose a powder flame spray gun when you need wear-resistant alloys, ceramics, or carbides. Choose a wire gun for plain zinc or aluminium anti-rust work.
How to Choose the Right Powder Flame Spray Gun
- Coating material: self-fluxing alloy, tungsten carbide, ceramic, or metal powder.
- Job type: hand-held repair (5 PM-II) or higher-rate work with a feeder (6 PM-II).
- Fuel gas: acetylene, propane, LPG, or hydrogen, based on what your site supplies.
- Powder feeding: built-in canister or separate feeder.
- Surface prep: pair the gun with a sand blasting machine, because powder coatings need a clean, rough surface to bond.
- Booth and accessories: a spray booth, compressor, and safety wear if you are setting up a shop.
