The Carlisle CC and CC “Plus” Burners are known as cannon style burners. Their large outer case and tremendous flame output resembles the profile of a “cannon”. These burners may be used with a mixture of oxygen and either natural gas, propane, or hydrogen (different tips are suggested depending on the gas used). Both burners produce two distinctive flames, the centerfire (premixed) and the outer fire (surface mixed). The centerfire, which has characteristics of a single ported tip, produces a pre-mixed flame similar to what may be achieved with a Carlisle hand torch. There are three types of centerfire tip. The first is the #5 centerfire tip. This tip has a larger orifice than the #3 centerfire tip and produces more BTU’s. The #3 centerfire tip produces a more defined centerfire flame. The last type of centerfire tip is the hydrogen tip which is for use with hydrogen gas and has the same orifice size as the #5 centerfire tip. The #5 and #3 centerfire tips utilize piloting. The hydrogen tips are unpiloted. The outer shell of the CC is manufactured from brass (stainless steel optional). The brass shell is threaded onto a machined mixer body. For fuel gas and oxygen supply, four metering valves are attached to the back of the mixer body. These valves are color coded for ease of use. The oxygen valves have green handles while the gas valves have red handles. On a standard CC these valves are interconnected by crossover attachments to limit the feed hose requirements to two. The CC series is also available with four separate inlets to allow for the use of foot controllers. The standard hose connections for this configuration are welding hose “B” fittings. Other connection types are available such as hose barbs and JIC connections.
The CC series has several base styles available. The standard style is a Ball & Post mount. The Ball & Post utilizes the crescent shaped solid steel base with a ball and socket connection. The post that extends upward is threaded directly into the bottom of the CC body. This style offers a selective articulation. In order to adjust the angle of the head, the user manually releases a thumb screw in the cast iron base. When re-tightened, this provides positive burner positioning. The Rack & Pinion style mount utilizes a pinion gear to pivot the burner in an arc, offering greater range in positioning than the Ball & Post mount. The user can adjust a knob on the side of the mounting device for quick, accurate positioning. A Heat Exchanger is standard on the CC burner. Manufactured from aluminum, the Heat Exchanger dissipates heat from the burner body. The Heat Exchanger has cooling fins providing increased surface area for the transfer of heat. The heat shields protect the user from the inevitable heat buildup on the brass body, caused by the radiant heat from working large pieces of glass. The CC can also come with the “Air Optimizer”. This utilizes a compressed air “Bleed” into the fuel gases through two Venturi mixers mounted at the burner valve body. By premixing the gas, the optimizer decreases the BTU capacity per cubic foot of a specific fuel gas. This changes the dynamics and flame characteristics. With propane, the flame becomes more focused and narrow with the use of the optimizer. In order to produce the same amount of heat, a greater volume of gases must pass through the burner. As the flow increases, the gases travel faster. High gas velocity results in less heat transfer back into the burner, allowing the burner to operate cooler. Compressed air is less costly than compressed oxygen which saves money too.
