2. Preparations for Use
2.1. Gas connection
Secure the gas cylinder against falling over. Use an adjustable pressure regu-
lator(0to2.5bar)andashbackarrester.Connectanapprovedgashoseline
foracetylenetothegascylinderrespectivelyashbackarresterandthreaded
socket(3)oftheacetylenetorch.
WARNING
 BSPP⅜”left-handthreadsineachcase.Setthegaspressureto1bar.Check
the system for leaks.
3. Operation
CAUTION
 Wearprotectiveglasses!
3.1. Solderingtorchacetylene
Open the gas cylinder valve; if necessary set the gas pressure as des cribed
under1.Theintegralvalveinthetorchisopenedbyoperatingthetrigger(1).
Simultaneously,thesparkgenerator(piezoigniter)projectsasparkintothe
torch pipe, igniting the gas. On ignition, a loud report is produced; this has no
effect on the functioning of the apparatus. Following a new connection or
reconnection to a gas cylinder, it may be necessary to operate the trigger
repeatedly until the air has been expelled from the hoseline.
When the trigger is released, the valve in the torch closes, cutting off the gas
supply,andtheamegoesout.
 Ifthelockingbutton(2)ispressedwhenthetriggerisoperated,thetriggerwill
stay on and the torch will continue to remain lit. When the trigger is operated
again, the locking button will be released. When the trigger itself is then released,
theamewillgoout.
For brazing operations,thetipsofthecircularameshouldtouchthework-
piece. For soft soldering operations,thetipsoftheamescanbeheldata
distance of 10 – 30 mm from the workpiece, depending on the size of the pipe.
NOTICE
 Donotreducethegaspressureandalwayspressthetrigger(1)tillthevery
end,otherwise,duetoareducedame,thetorchpipeandsparkgenerator
may be damaged.
CAUTION
When the torch is no longer required, close the gas cylinder valve and allow
the residual gas in the hoseline and torch to burn off.
3.2. Soldering material
For brazing operations,useROLLER’SLotP6.Copperpipesandttings
mustnotbetreatedwithuxbutintheirbaremetalstate.Forothermaterials,
suchasbrass,itmaybenecessarytouseux.
For soft soldering operations, use ROLLER’S Lot Cu 3. Copper pipes and
ttingsmustbetreatedasbaremetal.Topreparethesolderedarea,apply
ROLLER’S Paste Cu 3 to the pipe section. This paste contains soldering powder
andux.Theadvantageofthepasteliesinthefactthatthetemperaturerequired
forsolderingcanbeidentiedbyachangeofcolourintheheatedpaste,thus
ensuringthatthesolderedjointisproperlylled.Inanycase,however,ROLL-
ER’S Lot Cu 3 must be inserted afterwards. ROLLER’S Lot Cu3 and ROLLER’S
Paste Cu 3 have been specially developed for drinking water pipes and comply
withthespecicationslaiddownbytheGermanFederationofGasandSanitary
Engineers(GW2andGW7)andtherelevantDINstandards.
4. Maintenance
Maintenance and repair operations on the torch must not be carried out other
thanbyqualiedpersonnelorROLLERaftersalesservicecentres.Norepairs
ormodicationstothetorcharepermittedbyunauthorisedpersons.
Before undertaking any maintenance or repair operations, close the valve on
the gas cylinder and allow any residual gas in the hose and torch to burn off.
 Toreplacethetorchnozzle,torchpipeorsparkgenerator,unscrewtheve
screws from the housing and remove the upper part of the housing. Now remove
the torch from the lower part of the housing. Pull off the torch pipe and nozzle
retainer. Replace the nozzle retainer with torch nozzle, torch pipe or spark
generator.
5. Action in Case of Trouble
5.1. Fault: Torchwillnotigniteorproducesweakame.
Cause: ● Gas cylinder empty.
● Gas cylinder valve closed.
● Pressure incorrectly set.
● Hose defective.
●  Torchnozzleobstructed(see4.).
5.2. Fault: Torchwillnotigniteautomatically(butcanbelitwithe.g.amatch).
Cause: ●  Sparkgenerator(piezoigniter)defective.
