This is the latest technology in flame spraying. Technical director, Adam Wintle explains that the new 17E uses an electric drive motor instead of the traditional air turbine drive system. The older air turbine drive system uses a number of gears and shafts to drive the wire and a braking system to control the speed of the wire feed. Most of the older turbine air drive guns requires a lot of attention including gear lubrication and servicing of the guns is often expensive. The new 17E gun utilises the latest German technology with its ceramic bearing electric drive motor eliminating all the gears and shafts inside the main body of the gun. This new motor has been tested for over 3000 hours and is still running flawlessly. The system comes with a separate electronic drive box for controlling the speed of the wire. Another new option is the safety release option, which, if the gun is dropped the gas supplies are cut off automatically. The Metatherm 17E can use a combination of either acetylene and oxygen or propane and oxygen gases.
