=== Lighting the Torch ===


THE INSTRUCTIONS ARE NOT YET WRITTEN FOR THIS TORCH
==== If using the [[Carlisle CC Torch]] ====
# Light and adjust the [[Carlisle CC Torch]] following the instructions on that page
# Install the desired tip on the [[Smith Little Torch]]
# Adjust the Smith Little Torch's regulators to the pressures specified for the torch tip selected, per the chart below
# 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.
# 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
# Slowly open the oxygen valve till the flame turns blue, with a clear inner cone of brighter blue.
## If there is significant yellow/white in the flame, this is a reducing flame, add oxygen or reduce fuel.
## If the inner cone becomes very sharp and the torch hisses loudly, this is an oxidizing flame, add fuel or reduce oxygen.
## Adjust the torch regulators as necessary with the torch lit to maintain the pressures specified for the torch tip selected, per the chart below.
## Readjust the flame balance as needed after adjusting the regulators.


== Shutting Down The Torch ==
==== If not using the [[Carlisle CC Torch]] ====


THE INSTRUCTIONS BELOW ARE COPIED FROM THE SMALL SINGLE STAGE TORCHES, THESE INSTRUCTIONS NEED TO BE MODIFIED FOR THIS 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).
 
# 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).
# Check that both Regulators on the bottles are backed out/reduced to minimum pressure (counter clockwise to reduce pressure).
# Check that both Regulators on the [[Smith Little Torch]] are backed out/reduced to minimum pressure (counter clockwise to reduce pressure).
# 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.
# 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).
## Do not light the torches unless both propane and oxygen gauges indicate between 5 and 30 PSI.
# Install the desired tip on the [[Smith Little Torch]]
# Adjust the Smith Little Torch's regulators to the pressures specified for the torch tip selected, per the chart below
# 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.
# 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
# Slowly open the oxygen valve till the flame turns blue, with a clear inner cone of brighter blue.
## If there is significant yellow/white in the flame, this is a reducing flame, add oxygen or reduce fuel.
## If the inner cone becomes very sharp and the torch hisses loudly, this is an oxidizing flame, add fuel or reduce oxygen.
## Adjust the torch regulators as necessary with the torch lit to maintain the pressures specified for the torch tip selected, per the chart below.
## Readjust the flame balance as needed after adjusting the regulators.
 
=== Shutting Down The Torch ===
 
==== If using the [[Carlisle CC Torch]] ====
# Turn off the [[Smith Little Torch]] by turning the torch oxygen valve off, then turning the torch propane valve off.
# Follow the instructions on the [[Carlisle CC Torch]] page to shut down and depressurize the gas system.
 
==== If not using the [[Carlisle CC Torch]] ====
# 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).
# Ensure the Griffin Glass Torch Foot Pedal in the ON position.
# Turn off the [[Smith Little Torch]] by turning the torch oxygen valve off, then turning the torch propane valve off.
# 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.
# Ensure the vent hood is ON during gas burnout.
# Firmly shut the valves on both the oxygen and propane bottles.
# Without opening the bottle valves, light the torch using only the propane, and allow all the propane gas to burn out of the lines.
# When the propane only flame goes out, close the propane valve on the torch.
# Open the oxygen valve at the torch to release the oxygen from the lines.
# Close the oxygen valve on the torch.
# Turn both torch regulator knobs counterclockwise (decrease) as far as they will go to relax the regulator diaphragms.
# Turn both bottle regulator knobs counterclockwise (decrease) as far as they will go to relax the regulator diaphragms.
