Carlisle Machine Works Welder, High Oxy Mini CC, Pinpoint Mini CC Instruction Sheet

Mini CC Burner Instruction Sheet

The Mini CC Burner uses propane, natural gas, or hydrogen with oxygen to create a wide range of flame
characteristics for flameworking applications. This instruction sheet is designed to provide the user
with a working knowledge of the burner to allow for safe and educated use. 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.

Mini CC Instructions-1

Control Valves:

Standard models require two valves which are, located on the back of the Mini CC Burner. 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
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”

)

Checking for Leaks:

Before operating the Mini CC Burner for the first time and once a month (see
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 residual water.

5. Mix soap (liquid soap is best for this) and water to form a bubbly mixture for leak detection.

6. Turn on both control valves.

7. Apply the soapy mixture to all threaded connections and valve stems. If any of these areas
produces bubbles after applying the soapy mixture, the connection may have a leak.

8. Close all control valves and disconnect the air.

If a leak is detected, contact a Carlisle Representative for assistance.
