This instruction sheet is not intended to be a guide for flameworking, but rather a guide for use of the Mini CC Burner. Please take the time to thoroughly read through this instruction sheet to help ensure the proper use and maintenance of the burner. This instruction sheet provides information about the Mini CC Burner. High Oxy Mini CC For the broadest range of flame types and the ability to work with a wide range of applications, the high oxygen Mini CC offers an extra oxygenated flame. This allows for a high heat output with the upper range to work with hard glass. Pinpoint Mini CC A special center fire allows the Pinpoint Mini CC to have a focused narrow surface-mixed flame. Options and Accessories: The Mini CC Burner has several options and accessories that are available. This section is intended to provide any pertinent information for the options that may be applicable. • Stainless Steel Head Option: Replace the brass nozzle with all stainless steel construction for longer life and cooler operations. • EL-2 Foot Controller / RMB Foot Controller: The EL-2 is an electronic foot-actuated positive closing valve system. The RMB is a variable metering valve system that is metering only, not positive closing. • In-Line Disposable Filters Option: This is a highly recommended option to filter the fuel gas (except hydrogen) and oxygen gases prior to the burner to reduce the possibility of containments from the feed piping and supply sources. • Hose Options: There are many hose options. Latex hose, Welding hose, Tygon hose, Stainless Steel Braided Hose, and Teflon lined hose to name a few. Refer to Bulletin 24D on the website for ordering. Surface Mixed: The Mini CC Burner is surface mixed. Surface mixed burners deliver the gas and oxygen to the face separately so that the mixing of gases happens as they exit the burner face. This produces a safe flame for working with any application. Surface mixed burners do not have the possibility for combustion to take place inside of the burner (this is commonly known as Flashback) since the gas and oxygen are not mixed until they exit the burner. However, certain conditions (such as an internal leak) could cause a Flashback to occur. Carlisle Machine Works, Inc., P.O. Box 746, 412 S.

One control valve has a red handle and is used for metering the gas flow to the burner. One control valve has a green handle and is used for metering the oxygen flow to of the burner. These control valves are finely threaded and thus require several full turns to become fully open or fully closed. When using these valves to control the flames, it is best to make small incremental adjustments rather than full turns. Quick or large adjustments could cause the flame to become unstable and even blow off of the face of the burner. In time, the user will learn the best way to control the burner for their application. The valve stems are threaded and secured into the valve body via a nut. This nut is threaded onto the valve body and the stainless steel stem extends through this nut. Depending on how tightly this nut is threaded down onto the valve body, the stainless steel stem will be harder or easier to turn. If the nut is tightly threaded down onto the valve body, the stem will have more resistance to movement. By loosening this nut, the stem will become easier to adjust. Loosening the nut can also cause a leak to form around the stem from the nut sealing area. Be sure to check for leaks (see “Checking forLeaks”) anytime that this nut is adjusted. When closing the control valve, the valve should be adjusted only until it seats and stops turning. The valve should not be forced or “torque” down any further. By turning the valve handle with force, beyond its seal positioning, once it has seated, great pressure may be placed on the seat. This will cause the seat or valve stem to become deformed and will result in a leak that can not be fixed and will require the replacement of the valve. Checking for Leaks: Before operating the Mini CC Burner for the first time and once a month (see “Maintenance”) the burner should have the control valves and all connections checked for leaks. Follow the procedure below to check for leaks. 1. Connect air at 25 PSI to the burner. 2. Dip the head of the burner into a bucket of water. 3. Cycle through the control valves turning each one on and then shutting it off. When the control valve is opened there should be a rush of bubbles in the water. After shutting the control valve off, wait about 30 seconds to watch for any new bubbles. If bubbles appear at any rate, this would indicate a leak in the control valve. 4. Remove the head from the water and use the air pressure to blow out any r...
