The GMA Sprayjet-5MC Flame Spray Gun has been designed and built to be the best production flame spray gun for flame spraying coatings with metallizing wires. It is the product of extensive engineering know-how and on-the-job experience by the largest producer of flame spray equipment.
The taper valve used for many years on GMA gas heads has been replaced on the SPRAYJET-5MC with a new gas head cylinder valve. This new valve uses O-Rings to seal fuel gas, oxygen and air and to keep dirt out. It has eliminated the need for a precisely fitted, tapered plug for gas sealing. Some features of the new valve are :
Lubrication and maintenance are seldom require
Valve parts may be replaced by the customer. Taper valve lapping is no longer necessary.
Valve operation is smooth and uniform. Tendency for valve sticking and jamming has been designed out of the new valve.
The need for valve adjustment has been eliminated.
The standard machine is set up to spray 3/16” wire using acetylene as the fuel gas. It will handle all kinds and sizes of metallizing wires from 4.76 mm down to 1.6 mm dia.
The controlled speed range of the SPRAYJET-5MC with standard gears permits adjustment of the wire speed from about 9 inches (229 mm) per minute. A special, easily installed, high speed gear set is available for continuous spraying of the lower melting point metals such as aluminium and zinc. It provides a top speed of about 40 feet (12,192 mm) per minute. For production applications requiring continuous low speed operation, a special low speed set of gears is available. This gear set provides high torque at wire speeds between 6 inches & 9 ½ feet per minutes.
The totally enclosed electric drive motor is light, robust power source for feeding wire through the machine. The key to the power and light weight is the small amount of compressed air which flow through the motor. It is cooled and pressurized by clean compressed air to avoid contamination by metal dust and shop dirt.
