Elmaflame units generate a mixture of hydrogen and oxygen from demineralized water in an electrolytic process.
After further processing the mixture burns without residues in a micro flame.
Temperature and energy of the micro flame can be adjusted individually to each soldering or welding job by selecting the suitable nozzle size and the type of vapourizer liquid. The high temperature gradient of the micro flame
allows operation of the unit in close proximity of temperature-sensitive components.
Elmaflame units are equipped with a specialized part on the top. Due to the special conduction of the gas, operation, maintenance and functional checks are easy to do; also, the forming of condensate inside the unit is prevented which increases the reliability and prolongs the service life of the units considerably.

The units are very safe to operate because gas is produced only when it is required. When the burner valve is
closed, the production of gas is automatically shut down, too. Due to the extraordinarily low power consumption
and the low cost of operating media (distilled water, vapourizer liquid) the operating costs of these units are kept
extremely low compared to other units.
The Elmaflame units are fitted with a quick analogous pressure control device so that working on a number of
different jobs and workplaces with one unit is no problem. The operating pressure is variable and the set pressure
keeps precisely at the required level even under changing ambient conditions.
Additional advantages:
• High-level safety standard in compliance with DIN 32508
• Hydrogen-oxygen mixture burns clean without residues
• Easy operation, microprocessor-controlled with integrated leak detector
• Single or multi workplace operation possible
• Quick regulation of the precise operating pressure, automatic adjustment
• LED lighting for functional check and filling level monitoring of vapourizer liquid
• Almost no operating sound due to the temperature-controlled cooling device („whispering cooling“)
• Housing and gas reactor made of high-quality stainless steel
• Low operating costs
• Exchange of electrolyte is not necessary over many years
• Any losses of liquid during operation is compensated by refilling distilled water
• No mineral mineral wool padding required for the drying of the gas

electrolyte containers with water. Then the container can be
disposed of into the ordinary waste. We recommend to contact
the local authorities for information on the use and waste
disposal of electrolytes.
Risks caused by
vapourizer liquid
Risks caused by
burnable gas and gas
flame
Risk of fire and explosion! The vapourizer liquid is a
flammable substance! Keep away from ignition sources while
filling vapourizer liquid into the unit!
Avoid inhaling the vapours! Do not eat, drink or smoke while
handling the vapourizer liquid! Wear goggles and gloves!
The Elma vapourizer liquid elma redux is not toxic. When using
other, methanol-containing vapourizer liquids, take into
consideration that these substances may be highly toxic! Read
and observe the relevant instructions on the labels of the
products used.
Risk of fire and explosion! Do not leave the unit switched on
unsupervised. The gas escaping from the unit is highly
flammable and explosive. The switched-on unit must be
operated with opened valve only until the flame ignites. Any
escaping gas which does not burn in a flame causes a high risk
of fire and explosion! For refilling the reactor keep away from
ignition sources! Even the open pressure-less reactor contains
highly explosive burnable gases.
To prevent the creation of electrostatic sparks immediately
before opening the reactor (e.g. for checking the filling level or
for refilling distilled water), touch the cap nuts on the top part of
the unit or the metal screws on the housing with both hands.
Risk of burning and fire! Hang the burner hand piece with
burning flame onto the soldering stand for short operating
stops. Ensure that there is a sufficient distance between the
flame and any flammable items. Ensure that there is sufficient
ventilation for all soldering and welding operations!
Exclusion of liability
The manufacturer cannot be held liable for damages on
persons, equipment or work pieces caused by improper use.
The operator is responsible for the correct instruction of the

3 Description of operational process
Operational principle
Adjustment of the
microflame
Elmaflame units produce a hydrogen flame with very high
temperatures of up to approx. 2850°C.
In the integrated stainless-steel reactor, detonating gas is
produced through electrolysis from distilled water.
The detonating gas is guided from the reactor to a condensate
separator to dry. Then, the gas is enriched with solvent vapours
in a vapourizer tank. The processed detonating gas is then
conducted through the gas hose to the burner hand piece via a
backfire protection device.
If the detonating gas ignites, it reacts releasing heat. The
remainder of the reaction is water (H
O).
2
Temperature and energy of the burner flame can be adjusted to
the soldering or welding job by the selection of a suitable nozzle
size and the type of vapourizer liquid.
Stand-by mode
Economic efficiency
The fine adjustment of the quantity of delivered gas is carried
out by the regulating wheel on the burner hand piece. The
operating pressure can also be set at the operating panel
depending on the required energy of the flame.
As soon as the valve at the burner hand piece is closed the gas
production is automatically interrupted.
Depending on the temperature of the electrolyte reactor the
ventilation device keeps on operating for a certain period of
time until the reactor has cooled down to 45°C. The ventilation
device is fitted with 3 speed ranges which are controlled
electronically.
The extremely low energy consumption and the low cost of
consumption goods (distilled water, vapourizer liquid) ensure
extraordinarily low operating costs compared to other
procedures.
The Elmaflame units comprise the latest soldering and welding
technology.
The special top part makes operation, maintenance and
functional checks particularly easy. There is almost no
condensation inside the unit due to the special gas guiding
device. This increases both reliability and service life of the
units.
The Elmaflame units are equipped with a quick analogous
pressure control to allow operation of the units on changing jobs
or on more than one workplace. The operating pressure is
variable and is automatically kept precisely at a constant value
even when the ambient conditions change. Additional
advantages:
• Very high safety standard in compliance with DIN 32508
• Hydrogen-oxygen mixture burns without residues
• Easy operation, microprocessor-controlled, with integrated
leak detector check
• Quick regulation of the precise operating pressure with
automatic adjustment
• LED indication for functional check and monitoring of
vapourizer liquid filling level
• Almost noiseless operation with temperature-controlled
ventilation device („whisper cooling“)
• Housing and gas reactor made of high-quality stainless
steel
• Single or multi-workplace operation possible
• Low operating costs
• Change of electrolyte not necessary over many years. Any
losses of liquid due to operational processes are
compensated by refilling distilled water.
• No mineral wool padding necessary for drying the gas.
Elmaflame units are designed and manufactured in compliance
with the latest technology standards. Operation is safe provided
that the safety and operating instructions are observed and
provided that the units are used only for applications for which
they are intended.
Safe operation of the units is ensured by means of the following
safety devices.
• Gas pressure monitoring by means of safety pressure
switch
• Temperature monitoring of the reactor and of the
transformer
• Flame stop (backfire protection device) made of sintered
metal integrated in the burner hand piece
• Flame stop (backfire protection device) at gas outlet
• Reactor housing (pressure vessel) made of stainless steel
• EMC
• Mains fuse
A high operating safety is guaranteed because gas is produced
only when it is required (i.e. when the valve at the burner hand
piece is open).

connection nut.
Then tighten the connecting nut by means of the fork
wrench. For this, hold the reactor at the filling duct with one
hand. A slight movement of the reactor is possible and
harmless because the reactor connection is elastic. Tighten
the screw connection fast to avoid leaks in the pressure
system.
4. Connect the gas hose of the burner hand piece to the outlet
on the top part (C).
The unit top part is movable to facilitate the removal of the glass

electrolyte
If the electrolyte solution must be produced from solid
potassium hydroxide (KHO) by the customer, proceed as
follows.
Use the following substances only:
• Potassium hydroxide (cookies or flakes – free of water):
KOH quality: KOH must be contaminated with max. 1.5%
potassium carbonate.
1. Fill the correct amount of distilled water into a temperatureresistant and alkaline-resistant container.
2. Add the correctly measured quantity of potassium hydroxide
carefully and slowly, keep stirring the mixture.
Caution! The liquid may splash. Strong reactions due to
self-activated heating and the forming of vapours are
possible. Observe the safety warnings indicated in this
section!
3. Keep stirring the liquid until the potassium hydroxide has
completely dissolved.
4. Let the heated alkaline solution cool down.
1. Unscrew the closing cap from the filling duct (see illustration
5.2.D.) at the electrolyte reactor.
2. Place the clean funnel (included in the delivery volume) onto
the filling duct.
3. Carefully pour approx. 4/5 of the electrolyte (total quantity
see table in this section) into the filling duct of the reactor.
4. Carefully insert the glass floating body into the filling duct of
the reactor, with the thin end up. The marking on the floating
body must be level with the edge of the duct. If necessary
refill liquid.
The glass floating body must not stand out from the edge of
the duct by more than 5 mm.
Caution! In case of an overfilling there is a risk of damage
to the unit. If the reactor has been overfilled the excess
electrolyte must be removed from the reactor (for this
carefully read and observe the relevant safety warnings and
instructions in section 8.7.!).
The glass floating body remains in the filling duct for future
filling level checks.
5. Screw the closing cap back onto the filling duct and tighten
it.
Illustration 5.3. Filling duct with glass floating body, showing the
maximum filling level
5.4 Filling of the vapourizer glass with vapourizer liquid
The use of vapourizer liquid is necessary for the soldering of
metals (except platinum). The flowing gas is enriched and
thereby produces a flame which is adjusted to the individual
properties of the metal.
We recommend the use of elma redux (Elma Order No. 580
000 9886)as vapourizer liquid. Unlike other methanolcontaining liquids elma redux is not toxic. Another
advantage is that the burner hand piece cannot be blocked
by residues which may be contained in other media
(borax). In these cases the hand piece must be replaced.
Vapourizer liquids are flammable! Therefore, please observe
the following safety instructions before filling.
Risk of fire and explosion due to ignition sources and
electrostatic charging!
CAUTION!
Risk of ignition of the flammable liquids used for filling due to
ignition sources around the workplace!
18
Keep away from ignition sources when the vapourizer glass is
open or when you handle vapourizer liquid!
Risk of ignition of the flammable vapourizer liquids used for
filling due to electrostatic discharging!
Touch the cap nuts on the holding angle pieces of the top part
with both hands for a short period of time before you handle the
vapourizer liquid. This will branch off any possible electrostatic
charge of the operator without any risk!
Ensure that the workplace is sufficiently ventilated!
Risk of poisoning by toxic solvents when methanol-containing
vapourizer liquids are used!
CAUTION!
Do not inhale the vapours!
Avoid contact with eyes and skin!
Wear protective gloves and goggles when handling hazardous
substances! Do not eat, drink or smoke!
Observe the specific safety warnings given on the label of the
vapourizer liquid used. Some types of vapourizer liquids may be
toxic!
Store open containers of vapourizer liquid that are not yet
empty at a safe place and keep out of reach of unauthorized
persons, in particular of children.
The maximum temperature of the hydrogen-oxygen flame is
approx. 2850
o
C. It is typical that the pure detonating gas flame
is almost invisible and the flame temperature is too high for
many applications. Therefore, the gas is guided through a
vapourizer liquid to reduce the energy density (flame
temperature). With Redux the temperature of the falme is
reduced to approx. 1800°C. In the same process the flame
becomes coloured which is desirable with a view to labour
protection.
How to proceed
For melting or soldering e.g. of platinum the flame does not
have to be enriched by vapourizer liquid. For these applications,
the vapourizer liquid can be removed from the vapourizer glass.
The high flame temperature which is necessary for the
soldering of platinum can also be reached by the use of water in
the vapourizer glass. The cleanness of the gas is improved
through the filtering effect of the water which allows the fast and
high-energy burning of pure hydrogen-oxygen mixture.
1. Open the closing cap of the vapourizer glass (see
illustration 5.4.A.).
2. Place the clean funnel (delivered with the unit) into the
fillling opening of the vapourizer glass.
3. Carefully fill vapourizer liquid into the vapourizer glass up to
the red maximum filling level marking (see illustration
5.4.B.).
4. Screw the closing cap back onto the filling opening and

6.4 Selection of the burner nozzle
The Elmaflame units are delivered with a selection of nozzles of
different sizes.
Allowed nozzle sizes
Elmaflame 140: 0.5 mm (G25) – 1.0 mm (G19)
Elmaflame 240: 0.5 mm (G25) – 1.5 mm (G17)
Elmaflame 300: 0.5 mm (G25) – 1.8 mm (G15)
The use of larger nozzles is not allowed.
The use of smaller nozzles is possible without problem. Select
the suitable nozzle from the nozzle set depending on the
required soldering job and fasten it onto the conical tip of the
hand piece.
6.5 Adjustment of the gas pressure at the
operating panel
Size and energy of the burner flame can be adjusted at the
valve of the burner hand piece (see illustration 6.6.) or set at the
operating panel by pre-selecting the gas pressure.
When the unit is ready for operation the display shows 2
different operating pressure values:

Example
First part of display top line: shows the actual value (mbar)
measured in the unit.
Second part of display top line: shows the actual reactor power
required to produce the set gas pressure. The display shows a
value between 0% and 100%.
Shows the actual set pressure value (mbar) in the unit.
The set pressure value can be changed during operation by the
keys
The actual pressure is adjusted to the set value within a very
short time.
The maximum operating pressure is limited to 200 mbar, the
minimum gas pressure is limited to 50 mbar.
The display shows the actual operating pressure in the top line,
e.g. 120 mbar. If the set pressure value is changed, e.g. to 180
mbar, the reactor starts operating at e.g. 75% power to reach
the new set value. The required reactor power depends on the
size and number of nozzle(s) and on the preset pressure value.
or .
120 mbar 75%
180 mbar (set v.)
24
Depending on the selected nozzle size of the burner hand piece
the required gas power is automatically adjusted so that there is
a perfectly suitable flame. The automatic pressure control
device keeps the pressure at a constant level by permanently
comparing set and actual values and by regulating the gas
production accordingly.
The gas pressure should be between 50 and 150 mbar
depending on the soldering or welding job. It may be necessary
to reduce the number of burners used at the same time or to
reduce the nozzle size.
The flame becomes „harder“ with increasing gas pressure, and
„softer“ with decreasing gas pressure. The Elmaflame unit
allows the perfect adjustment of the flame to each soldering or
welding job.
Please note! If the set gas pressure value is too low for the
selected nozzle size, so that the gas burning speed is higher
NOTE
than the gas escaping speed, the flame backfires into the
nozzle. In most cases, this will destroy the nozzle. The backfire
of the flame is stopped by the backfire protection device inside
the handle. In the process the backfire protection device is
contaminated and the gas flow-through capacity of the handle
piece is reduced. If this process is repeated several times the
handle piece can be choked.
6.6 Regulation of the burner flame at the burner
hand piece
Size and energy of the burner flame can be adjusted at the
valve of the burner hand piece (see illustration 6.6.) or set at the
operating panel by pre-selecting the gas pressure.
Do not control the burner flame down until the flame touches
the nozzle tip, as this may damage the nozzle.
Illustration 6.6. Regulation of the flame size at the burner hand piece
valve
If operation of the Elmaflame is stopped for a short period of
time the burner hand piece can be hooked into the holder
(delivered with the unit) with burning flame. Ensure that the
burner flame cannot ignite any flammable substances even if
the position of the burner tip changes. It may be safer to
extinguish the flame and to shut the burner valve at the hand
piece.
Always extinguish the flame and shut the burner hand piece
valve for prolonged operating stops. Switch off the gas
production at the key
The unit now automatically switches into stand-by mode. In this
operating mode, the ventilation device cools down the principal
components reactor, rectifier and main transformer at reduced
speed, so that there is no risk of overheating. When the unit has
sufficiently cooled down, the control system automatically
switches off the ventilation device.
In stand-by operating mode with cooled-down unit the current
consumption is reduced to a minimum.
The unit must be switched off at the mains switch only for
prolonged operating stops (overnight, over the weekend, over
holiday periods).
at the operating panel.
If the unit is switched off at the mains switch after a prolonged
operating period, damages to the unit due to overheating are
NOTE
possible.
6.8 Extinction of the flame at the burner hand piece
When the gas pressure is adjusted correctly, the burner flame
does not touch the nozzle, there is a distance of several tenths
of millimetre between nozzle and flame. The nozzle tip remains
cold and in perfect condition.
When extinguishing the burner flame ensure that the flame
does not touch the nozzle. This may burn out and damage the
nozzle.
Procedure
Procedure B
Reduce the flame at the burner hand piece valve; ensure that
the flame does not touch the nozzle tip. Blow out the flame.
Immerse the flame up to the burner tip into a glass of water for
a short period of time.
When the flame is extinguished shut the burner hand piece

8.1.1 Refilling of distilled water into the reactor
The reactivity of the electrolyte is sufficient for approx. 6000
operating hours (flame).
The quantity of electrolyte in the reactor is reduced by the
electrolytic process. Therefore, check the filling level in the
reactor regularly after approx. 8 hours of gas taking (flame).
Checking the filling level by means of the glass floating body is
possible only when the floating body has been placed inside the
filling duct for initial operation.
For this maintenance work read and observe the safety
warnings given in section 8.1. (e.g. protective goggles and
WARNING!
gloves)!
Check the filling level by means of the glass floating body
only. Do not light the filling duct with the burner flame for
better vision. Risk of explosion!
Check of filling level
of electrolyte
1. Extinguish the flame at the burner hand piece.
2. Press the on/off key
at the operating panel to switch off
the gas production.
3. Shortly open the burner hand piece valve (release the
residual pressure).
4. Open the screw cap of the filling duct (see illustration 5.2.D.)
of the electrolyte reactor.
5. Check the glass floating body in the filling duct:
The maximum filling level of the reactor is reached when the
upper edge of the glass floating body is level with the upper
edge of the filling duct (see illustration 5.3.B.). If the floating
body is several centimetres below this position, refill distilled
water.
6. For this put the funnel (delivered with the unit) onto the
filling duct and carefully fill distilled water until the upper
edge of the glass floating body is level with the upper edge
of the filling duct (see illustration 5.3.B).
Please note! When a large quantity of distilled water is refilled,
the floating body does not immediately indicate the correct
filling level as the specific density of distilled water is lower than
that of the electrolyte. Immediately after filling of a large quantity
of distilled water the floating body indicates a filling level which
is lower than the actual level. Therefore, refilling of distilled
water must be done step by step. The unit must be switched on
and the gas production started for approx. 30 to 60 seconds
between each refilling step.
How to proceed:

only a small quantity of distilled water until the floating
body is level with the filling duct edge.
5. Screw the closing cap back onto the filling duct and tighten
it.
8.1.2 Refilling of vapourizer liquid
Check of filling level o
vapourizer liquid
30
During operation of the unit, the vapourizer liquid is consumed.
It may be necessary to refill the vapourizer liquid.
When the level of the liquid in the vapourizer glass has gone
down to the sintered gas distributor (see illustration 5.4.C.) refill
vapourizer liquid.
The filling level of the vapourizer liquid can only be checked
with switched-on unit and built-up operating pressure.
After the unit has been switched off, there is a negative
pressure in the electrolyte reactor. This may lead to the suction
of vapourizer liquid into the compensation tank in the vapourizer
glass (illustration 8.1.3.G.). After switch-on and build-up of the
operating pressure the vapourizer liquid that has been sucked
into the compensation tank is pressed back into the vapourizer
glass.
Carefully read and observe the safety instructions before
you carry out this maintenance work!
WARNING!
How to proceed:
refilling of vapourize
liquid
1. Extinguish the burner flame at the burner hand piece.
2.
Switch off the gas production at the on/off key at the
operating panel
.
3. Open the closing cap of the vapourizer glass (see
illustration 5.4.A.).
4. Put the funnel (delivered with the unit) onto the filling
opening of the vapourizer glass (the funnel must be clean).
5. Carefully fill vapourizer liquid not higher than up to the red
filling level marking on the vapourizer glass (see illustration
5.4.B.). Caution! Avoid overfilling! There is a risk that the
vapourizer liquid may be sucked back into the dryer glass
due to the negative pressure which is created inside the
reactor when the unit is switched on.
6. Screw the closing cap back on the filling opening and
tighten it.
7. Now the filling process is finished.
After prolonged idle periods of the unit, the filling level of the
vapourizer glass can only be determined exactly after the unit
has been operated with correct operating pressure for a short
period of time.
Ensure that the filling level of the vapourizer liquid in the
vapourizer glass does exceed the level marked on the glass.
