If you need to put on high quality coatings that require "flame spray" or "thermal spraying" technology (like aerospace applications), this kit will get you into the game a lot cheaper than the $6500 the manufacturer wants new. You can use this for coating an object with even the highest temperature powders like ceramics, metal oxide, or molybdenum with temperatures up to 1900F (1040C). It can also be used with thermal plastics and low temperature metals like tin, zinc, etc., with accessories, see links below. When your buddies see the work this unit puts out, they will want one too, but they won't be able to find one used. Certainly not at this price. About thermal spraying, see the wikipedia article: http://en.wikipedia.org/wiki/Thermal_spray You can put on chrome coatings, machinable nickel, or copper alloys to reduce wear and protect against corrosion. Put on a mirror finish with stainless steel. Molybdenum steel for hard wear applications. Aluminum powder for RF shielding. Smooth nickel finishes for exhaust manifolds, etc., etc., etc. This is the unit you want to take your work to the next level. This unit has been used but it is in perfect condition and we guarantee that it works fine. But look at the price again. If you already have one of these you can use this one for spare parts and save yourself a lot of money. This one is a Sulzer-Metco 14E (it's a current product, see their website by poking around their website: http://www.sulzermetco.com ) from a flame spray booth that Boeing had. We guarantee that it works. They closed down the booth and we bought all the equipment, booth and all. We misplaced this gun and sold the booth without it. Now we found it, oops, and so, here it is, on eBay. You can get information on this gun from the manufacturer: http://pdf.directindustry.com/pdf/sulzer-metco/combustion-wire-solutions/23581-43043.html About thermal spray in general, see: http://149.168.34.62/ref/02/01424.pdf or the informative US Army publication: http://www.usace.army.mil/publications/eng-manuals/em1110-2-3401/ These guns apply metal coatings to metal surfaces. These are for corrosion or wear protection, to decorate or restore a surface (for example if it was corroded or worn, or even if that idiot over in the machine shop took too much off), or to improve electrical or thermal conductivity. They work by atomizing a wire which is blasted onto the surface with an oxy-acetylene welding flame, along with compressed air. Compressed air is also used to turn a turbine which advances the coating wire. Spray coatings are supposed to be harder and more resistant to wear because of the oxides that are mixed with the metal, along with quenching and work hardening. Density is 80% or better to that of castings of the same material. For bearing surfaces, the porosity is a good thing, otherwise it may need polishing and sealing. To buy wire, do a google search for "flame+spray+wire". Here are some suppliers: http://polymet.thomasnet.com/ or http://baystatesurfacetech.com/html/thermal_spray_wire-metal_alloy.html You also might be able to find the wire at a local high tech welding supplier. You can get spare parts, supplies (like gear and valve lube), wire, etc. from SpaCom. A link to their online catalog, with prices might be useful as you can order right off of it: http://www.spacom.com/searchresult.aspx?CategoryID=5 You will need an oxygen cylinder with regulator (42 to 194 ft^3/hour depending on fuel and wire size), acetylene cylinder with regulator (22 to 50 ft^3/hour), and a source of clean, dry, compressed air (65 psi, 30 ft^3/min). These are loud, you will need ear phones or eaqr plugs, respiration protection, and of course welding goggles. And it would be nice to have fuel, oxygen, and air flowmeters to help you set up quicker after you've got it running. We believe this is set up for acetylene gas, but these flame spray guns can also use hydrogen, or methane / natural gas. To change the gas type, you have to switch the nozzle or the siphon plug. We're including the hardware and handsome carrying case (11"x13"x7") shown. Payment must be recieved within 5 days after auction ends - Good Luck Bidding, Thanks
