Specifications

Caution!
- Cathode can be replaced without removing cathode assembly from torch.
After filing always check cathode length-!
- Do not apply the significant force when tightening the cathode with wrench because
the parts made of the base metals may be deformed, then the cathode assembly may
be broken down

.5 ozzle Status Check
Replace nozzle with a new one if nozzle bore diameter increases to . mm (0.05 inch)
for cutting and to .5 mm (0.1 inch) for welding Used cutting nozzles may be re-used
for welding by opening the nozzle bore with a 2.2-mm (0.085-inch) drill bit and
countersink with a 3.5-mm (0.14-inch) drill bit
Thread cathode into cathode holder and tighten with
combination wrench to achieve reliable connection but
without significant force
()see figure Verify cathode is
aligned with cathode holder by rolling cathode
assembly around on a level surface Align if required

If you use water with high mineral levels, mineral deposits will gradually form on the
evaporator. In this case, moisten the evaporator in water, and use a scraper or
sand paper to remove any mineral deposits. Using distilled water will help
prevent mineral deposits from forming on the evaporator.

2 Torch Disassembly ips and Techniques
Nozzle is jammed in cap: press it out with plunger
B Nozzle is “stuck” to evaporator: remove evaporator with nozzle, place cap over
nozzle such that cap and nozzle back edges align, and “break” nozzle off using cap
without exerting force
C Cathode is heavily melted remove evaporator and cathode holder from torch after
Section Step 8
D Cathode is melted to cathode holder: secure cathode holder in a vise and loosen
cathode with combination wrench or pliers
Caution!
Do not use force or impact on copper components
Evaporator Assembly Status Check
fine-
or metal brush
If required, clean quartz tube
of copper residue and soot by placing in acetic acid (or ferric chloride) for several hours
or by grinding with fine sandpaper under exceptional circumstances If copper residue
cannot be removed, install quartz tube to position copper-contaminated section in
tapered section of evaporator or replace with new one In the event
of chipping or cracking, replace tube Verify there is the radial thrust spring inside
evaporator at its rear thin end Make certain that cathode assembly is loose enough
inside quartz tube to be moved without much force
Cathode Assembly (Cathode Holder with Cathode) Status Check
Inspect tip of cathode In the event that there is a crater of over 0.3 mm (0.01 inch) n
cathode central insert and signs of copper pitting remove crater with file rounding
cathode tip into a cone shape
Measure cathode length Replace cathode if less than 15 mm (0.6 inch) in length (not
including threaded section
Apply graphite lubricant to cathode thread to avoid cathode fusion
cloth to remove excess graphite lubricant

- Within 5 seconds after pressing “ON” button, fully
depress start button (when cathode comes into
contact with ozzle, voltage will drop to V ,
and release it slowly voltage in initialized arc is
between and V
Several seconds later, a jet is supposed to
appear from torch nozzle while voltage will
increase to V

Caution
If arc fails to form display reading remains at V , press start button again
within 5 seconds
If you fail to press the start button within the specified time, display reading will fall to
V and “OFF” LED will illuminate If that were to happen, repeat start procedure
press “ON” button and press start button
If a jet fails to form within 8 to 10 seconds or an arc cannot be started deactivate torch

pressing the piston, fill until water starts to drip from the
nozzle (see figure)
After filling, close the filling neck cap tightly and wipe
