About this Item

This is a small handheld pre-mix torch, with an assortment of tips for different uses. it may be used for glasswork, jewelry annealing and soldering, Melting for casting, enameling, or many other purposes.

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

If using the Carlisle CC Torch

  1. Light and adjust the Carlisle CC Torch following the instructions on that page
  2. Install the desired tip on the Smith Little Torch
  3. Adjust the Smith Little Torch's regulators to the pressures specified for the torch tip selected, per the chart below
  4. Using the flame of the lit Carlisle CC Torch as an ignition source, slowly open the propane valve (red) on the torch while holding the tip near the Carlisle CC Torch flame till the Smith Little Torch lights.
  5. Adjust the propane valve so that the flame is stable, and there is no gap between the torch tip and the base of the flame
  6. Slowly open the oxygen valve till the flame turns blue, with a clear inner cone of brighter blue.
    1. If there is significant yellow/white in the flame, this is a reducing flame, add oxygen or reduce fuel.
    2. If the inner cone becomes very sharp and the torch hisses loudly, this is an oxidizing flame, add fuel or reduce oxygen.
    3. Adjust the torch regulators as necessary with the torch lit to maintain the pressures specified for the torch tip selected, per the chart below.
    4. Readjust the flame balance as needed after adjusting the regulators.

If not using the Carlisle CC Torch

This torch is plumbed to the same gas bottles as the Middle/Big Carlisle CC Torch on the bench, Be sure to identify the gas bottles which are connected to this torch by the labels on the hoses. The Smith Little Torch may be used without igniting the Carlisle CC Torch, simply ensure all four valves on the Carlisle CC Torch are in the off position (Clockwise).

  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. 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.
  5. 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.
  6. Install the desired tip on the Smith Little Torch
  7. Adjust the Smith Little Torch's regulators to the pressures specified for the torch tip selected, per the chart below
  8. Using the striker, light the torch by striking near the tip of the torch and slowly opening the gas valve (only gas, no oxygen) till the flame ignites and is sustained.
  9. Adjust the propane valve so that the flame is stable, and there is no gap between the torch tip and the base of the flame
  10. Slowly open the oxygen valve till the flame turns blue, with a clear inner cone of brighter blue.
    1. If there is significant yellow/white in the flame, this is a reducing flame, add oxygen or reduce fuel.
    2. If the inner cone becomes very sharp and the torch hisses loudly, this is an oxidizing flame, add fuel or reduce oxygen.
    3. Adjust the torch regulators as necessary with the torch lit to maintain the pressures specified for the torch tip selected, per the chart below.
    4. Readjust the flame balance as needed after adjusting the regulators.

Shutting Down The Torch

If using the Carlisle CC Torch

  1. Turn off the Smith Little Torch by turning the torch oxygen valve off, then turning the torch propane valve off.
  2. Follow the instructions on the Carlisle CC Torch page to shut down and depressurize the gas system.

If not using the Carlisle CC Torch

  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. Ensure the Griffin Glass Torch Foot Pedal in the ON position.
  3. Turn off the Smith Little Torch by turning the torch oxygen valve off, then turning the torch propane valve off.
  4. 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.
  5. Ensure the vent hood is ON during gas burnout.
  6. Firmly shut the valves on both the oxygen and propane bottles.
  7. Without opening the bottle valves, light the torch using only the propane, and allow all the propane gas to burn out of the lines.
  8. When the propane only flame goes out, close the propane valve on the torch.
  9. Open the oxygen valve at the torch to release the oxygen from the lines.
  10. Close the oxygen valve on the torch.
  11. Turn both torch regulator knobs counterclockwise (decrease) as far as they will go to relax the regulator diaphragms.
  12. Turn both 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.
