About this Item

This is a mid-sized, 2-stage glassworking torch. It has a single port premix centerfire burner surrounded by a 51 port surfacemix outerfire burner.

Plumbing for Two Stage Bench Torch With Hand Torch

The Carlisle CC Torch and Smith Little Torch are plumbed together sharing the same pair of bottles per the the below diagram. The Smith Little Torch has it's own regulators to reduce the gas pressure below the pressure required for the Carlisle CC Torch. The Carlisle CC Torch outer fire is connected via a Griffin Glass Rock-It 05 Foot Pedal with Oxygen Bypass to allow the user to rapidly turn the outer fire on and off without having to readjust the flame each time. The Oxygen bypass allows a small amount of oxygen to flow through the outer fire when it is off to prevent to torch face from overheating when using the inner fire only.

Operation

Lighting the Torch

This torch is setup as the Middle Torch on the bench, Be sure to identify the gas bottles which are connected to this torch by the labels on the hoses.

Note that for the Carlisle CC Torch, the middle two valves control the inner fire, and the outer two knobs control the outer fire. The outer fire must NEVER be lit without the inner fire also lit and adjusted first. The Outer fire oxygen must also always be at least slightly on to provide cooling for the torch nozzles, even when only using the inner fire.

1. Check that all four valves on the Carlisle CC Torch are shut (clockwise to shut, Red is propane, Green is oxygen) AND That both valves on the Smith Little Torch are shut (clockwise to shut, Red is propane, Green is oxygen).
2. Check that both Regulators on the bottles are backed out/reduced to minimum pressure (counter clockwise to reduce pressure).
3. Check that both Regulators on the Smith Little Torch are backed out/reduced to minimum pressure (counter clockwise to reduce pressure).
4. While lighting the torch, ensure the Griffin Glass Torch Foot Pedal is in the ON position. Press the pedal FOWARD to turn the outer fire ON, and press the pedal BACK to turn the outer fire OFF.
5. Open the gas bottle valves, crack open slowly till pressure shows on gauges and then open fully so that the valve is firmly backseated to prevent gases from leaking at the valve stem.
6. Adjust the gas bottle regulators for each gas so that the outlet gauges read 12 PSI for the propane and 25 PSI for the Oxygen (clockwise to increase pressure, note that pressure will not decrease till the torch valves are opened).
   1. Do not light the torches unless both propane and oxygen gauges indicate between 5 and 30 PSI.
7. Ensure the vent hood is ON any time the torches are lit.
8. Using the striker, light the Carlisle CC Torch Inner Fire (middle two valves) by striking near the tip of the torch and slowly opening the INNER gas valve (only gas, no oxygen) till the flame ignites and is sustained.
9. Adjust the gas till the flame is approximately 5-6” long using the INNER gas valve on the torch.
10. Check the gas bottle regulator outlet pressure. Adjust the gas bottle regulator till the outlet pressure reaches 12 PSI with the torch still lit. It may be necessary to adjust the torch INNER gas valve intermittently while adjusting the pressure regulator to maintain the flame size at 5-6 inches.
11. Slowly open the oxygen valve to introduce oxygen to the flame. The flame should brighten from yellow to white and blue. increase the oxygen flow till the yellow and white portion of the flame shrinks to central lighter blue spike at the center of the flame. The center spike should have the faintest hint of a yellow tip.
12. Check the Oxygen regulator outlet pressure. Adjust the Oxygen regulator till the outlet pressure reaches 25 PSI.
13. Using the INNER valves on the torch, adjust the oxygen and gas till the central spike in the flame has the faintest hint of a yellow tip. If the central spike is fuzzy and white/yellow, increase the oxygen or reduce the gas till the central spike in the flame has the faintest hint of a yellow tip.
    1. The blue portion of the flame beyond the spike should be uniform blue without streaks or gaps.
    2. If there are dark streaks or gaps in the blue portion of the flame, the central spike is a short sharp cone, or the torch is hissing loudly, This is an oxidizing flame. Decrease the oxygen or increase the fuel to reach neutral.
    3. If there are yellow/white streaks in the blue portion of the flame, or the whole flame is yellow/white, this is a reducing flame. Increase the oxygen or decrease the fuel.
    4. A picture of a neutral flame is below. need a picture
14. once the inner flame is lit and adjusted, crack open the OUTER oxygen valve just enough for the Inner fire flame to brighten slightly to a lighter blue.
15. Then open the OUTER propane valve till the outer fire is 8-12 inches long.
16. Slowly open the oxygen valve to introduce oxygen to the flame. The flame should brighten from yellow to white and blue, increase the oxygen flow till the yellow and white portion of the flame shrinks into 51 small white “candles” at the torch tip.
17. Using the OUTER valves on the torch, adjust the oxygen and gas till the 51 white “candles” in the flame are 8-16mm (⅜” to 3/4”) long. If the candles are rough or sharp looking with yellow streaks, increase the oxygen or reduce the gas till the tips of the candles are nearly smooth and white, with the slightest bit of fuzzy yellow at their tips.
    1. The blue portion of the flame beyond the candles should be uniform blue without streaks or gaps.
    2. If there are dark streaks or gaps in the blue portion of the flame, and the torch is hissing loudly, This is an oxidizing flame. Decrease the oxygen or increase the fuel to reach neutral.
    3. If there are yellow/white streaks in the blue portion of the flame, or the whole flame is yellow/white, this is a reducing flame. Increase the oxygen or decrease the fuel.
    4. A picture of a neutral flame is below. need a picture
18. once the INNER fire and OUTER fire flames have both been set to the desired size and balance, the foot pedal can be used to toggle between the inner fire and outer fire. Press the pedal FOWARD to turn the outer fire ON, and press the pedal BACK to turn the outer fire OFF.
19. If you plan to use the Smith Little Torch follow the directions on that page for lighting it as needed.

Shutting Down The Torch

1. Shutdown the torch with the Griffin Glass Torch Foot Pedal in the ON position, with the outer fire ON.
2. Turn off the torch OUTER fire using the torch OUTER valves. Decrease both simultaneously till the flame is small, then TURN OFF THE OXYGEN FIRST, THEN THE PROPANE.
3. Turn off the torch INNER fire using the torch INNER valves. TURN OFF OXYGEN FIRST, THEN PROPANE.
4. Ensure the Smith Little Torch if also off.
5. If you plan to keep working, you may leave the gas bottles open and the lines pressurized to relight the torch without re-adjusting the gas system. However, if you plan to stop for more than 15 minutes, please continue the following steps and depressurize the gas lines.
6. Ensure the vent hood is ON during gas burnout.
7. Firmly shut the valves on both the oxygen and propane bottles.
8. Ensure the Griffin Glass Torch Foot Pedal in the ON position.
9. Without opening the bottle valves, light the torch INNER FIRE using only the propane, and allow all the propane gas to burn out of the lines (You may open the OUTER propane valve on the torch to make this go faster).
10. When the propane only flame goes out, close the propane valves (Inner and Outer) on the torch.
11. Open the oxygen valve at the torch to release the oxygen from the lines (you may open the inner and outer to make this go faster).
12. Close the oxygen valves on the torch (Inner and Outer).
13. Open the oxygen and propane valves on the Smith Little Torch to release any gas trapped in it's lines.
14. Turn both Smith Little Torch regulator knobs counterclockwise (decrease) as far as they will go to relax the regulator diaphragms.
15. Turn both gas bottle regulator knobs counterclockwise (decrease) as far as they will go to relax the regulator diaphragms.

Lampwork Safety

Safety Glasses

• Didymium glass or polycarbonate safety glasses are required for anyone sitting at the torch working soft glass (Phillips 202 or Phillips Sodium Flare Poly lenses)
• UV blocking safety glasses or film glasses for any observers
• Hot glass can crack and pop as it cools, so eyes must be protected from flying shards
• The torch generates significant UV light that can lead to eye damage if not filtered by appropriate eye protection
• Soda lime glass generates a very bright flare when inserted into a flame that can cause eye damage if not filtered by appropriate eye protection

Fire/Flame Safety

• If anything related to the gas bottles, gas lines, torch, or flame seems wrong or there is unintended fire, IMMEDIATELY shut the bottle valves on the oxygen bottle and propane bottle.
• Always wear short sleeves or roll up long sleeves.
• When starting the torch, always light the torch with propane only, then add oxygen to the flame. When shutting off the torch, always turn off the oxygen then turn off the propane.
• Never reach into, in front of, or across the flame.
• Always ensure the torch is securely mounted to the table and the mount pivots are tight, with the torch pointed at an upward angle.

Hot glass and tool safety

• Any hot scrap glass bits should be placed in the water filled cullet cup so that hot shards are contained as they cool. If molten glass falls on the table or floor, pick it up with tweezers and put it in the cullet cup
• Place hot glass rods on the rod rack to cool, not on the table top.
• Always place tools and glass rods on the table or rack with the hot end away from you so that you do not accidently grab the hot end when picking them up

Fumes, Vapors, and Ventilation

• Always have the vent hood on when using the torches. Reducing or oxidizing flames generate unsafe combustion products, so keep the flame neutral as much as possible.
• Certain glasses and colors contain unsafe heavy metals and oxides that release toxic fumes when molten. While most standard colors release so little as to be safe, take extra caution with specialty colors advertised as high silver or uranium bearing, vent hood use is mandatory for these glasses.
• There is a process for coloring finished glass pieces called metal fuming. This process involves placing heavy metals directly in the flame which vaporize and deposit on the workpiece. Use extreme caution if you choose to do this, vent hood use is mandatory.
• Powdered glass and glass dust can cause silicosis (which is like a bad lung cancer that forms around particles in your lungs). Vent hood use is mandatory when working with powders, frits, or enamels, or when breaking glas rods and tubes.
