3) Inspect the collet washer for damage and replace if necessary.
ROD EXTENDER INSTALLATION
f.
Insert the cutting rod into the rod extender as follows:
1) Check to see that the collet in the rod extender is the appropriate size to properly fit the rod
being used and that the collet washer is present and in good condition. To replace the collet,
remove the collet nut and collet from the rod extender. Make sure the appropriate size collet
washer is in place. Insert the desired collet and replace the collet nut.
2) Loosen the collet nut one-half turn.
3) Insert the end of the rod that has the recessed internal rods into the collet until it is firmly
seated against the collet washer.
4) Tighten the collet nut to lock the rod in place.
5) Check for oxygen leaks at the collet nut. If a leak exists:
(a) Make sure the rod is firmly seated on the collet washer.
(b) Ensure the collet nut assembly is tightened.
(c) Inspect the rod for damage.
(d) Inspect the collet washer for damage and replace if needed.
(e) If the collet nut still leaks, remove the rod extender from service and turn in for repair.
2-7. RAPIDFIRE CUTTING ROD IGNITERS.
RapidFire cutting rod ignition cartridges are
used to light the cutting rods without the need for a battery, striker plate, and related cables. RapidFire
cutting rod ignition cartridges contain a material which when exposed to pure oxygen near instantaneously
heats to incandescence, in turn causing the cutting rod tip to quickly ignite.
The rod igniters utilized with the Prime-Cut torch contain oxygen reactive material, a pyrophoric /
self-heating solid / combustible in air. Combustion is achieved through rapid oxidation. Exposure to
high concentrations of oxygen will cause material to super heat into a molten state. Hazard Class:
4.2/ID #UN1383/DOT Label: Spontaneously Combustible. (Small quantities – 5 boxes or less- Hazard
Class 9/UN3363/Dangerous Goods in Apparatus.)
a.
General.
The rod igniter, utilized with the BROCO torch kits, contains an oxygen reactive material
that is enclosed in a small, airtight, hermetically sealed glass vial housed within a steel cylinder.
The reactive material is pyrophoric/self-heating/combustible in air. Combustion is achieved through
rapid oxidation. Exposure to high concentrations of oxygen will cause the material to convert to a
molten state. Should the activated material be exposed to air, the strips can be inerted by the
application of water, carbon dioxide (CO2), or foam. Material will self-inert in air over a time of
approximately 30-45 minutes.
