WHAT IS THE PROPER USE OF THE NOZZLE THREAD CHASER TAP?
All D/F Nozzles are hand checked for fit before and after plating, and checked again before shipping. If a nozzle has been installed on a
new complete torch, they have also been hand checked while being assembled.
The only reason to ever take a gas cup out a nozzle is to clean it. The nozzle and the gas cup must be blown out, and all of the threads
have to be wire brushed and blown out again before hand-tightening the gas cup back into the nozzle. If you can’t thread it in by hand
then something is wrong. Never force a gas cup into a nozzle.
When using the D/F Machine Specialties nozzle thread chaser taps, be sure to always follow the steps below:
Make sure that the nozzle is properly supported when tapping so it does not twist in the front of the torch body and cause damage. 1.
Improper support can cause the spigots to twist off the top of the rear nozzle collar, or damage the torch internal body parts. •
Note where the water ports go down the sides of the water-cooled nozzle (following down in line with the spigots). Too much direct •
pressure on these water ports could cause them to cave in and block of the flow of water.
Best practice is to hold the water-cooled nozzle in a vice with soft jaws, perpendicular to the spigots. •
Over-tightening of the vice can cause damage in general. •
Remove the tip from the front of the torch before tapping. 2.
Lightly lubricate the nozzle and nozzle thread chaser tap before tapping. 3.
Be sure to start the tap very carefully. Do not cross thread the nozzle. 4.
Be very careful to start threads correctly. Only tap 1/2 turn at a time, always backing up and removing chips 1/2 cycle at a time before 5.
moving forward. Do not try to tap further into the water-cooled nozzle than needed or past the factory thread depth.
Blow out the nozzle after tapping. Wire brush and blow off the gas cup before threading it back into the nozzle. 6.
If nozzle is badly deformed or damaged please return to the factory for a repair estimate before disposing of product (damaged parts 7.
can often be repaired).
