Aquaflame Flame Polishing and Micro Welding

Product Description

Aquaflame Flame Polishing and Micro Welding
Safe & Efficient Acrylic Flame Polishing without gas cylinder storage

A reliable, safe-operating solution for your acrylic edge polishing or micro-welding needs...

The Aquaflame 500, 800 and 1200 systems produce hydrogen and oxygen by the electrolysis of deionized water, in the ratio such that the hydrogen can be burnt in the oxygen. This produces a high energy heat source that is highly controllable and efficient. The only other by-product is water, making it truly efficient and environmentally safe.

Investment Casting:

Can also be used for micro-soldering circuit boards, medical instruments, jewelry and dental repairs.

The clean flame and precise control make the Aquaflame idea for edge-polishing or removing light scratches from Acrylics, even intricate shapes, in a single quick operation. Can also be used for micro-soldering circuit boards, medical instruments, jewelry and dental repairs.

Once the machine is filled it is ready to use. Does not require gas cylinders, so no need to store them. Only the addition of deionised water and Methyl-Ethyl-Ketone (MEK) from time to time is required. The fractional cost of these chemicals compared to gas will mean long-term cost savings.

LM138 - An additional battery operated Aquaflame Torchlighter. One Torchlighter is included with each machine. This additional battery operated torch lighter is available for safe and convenient torch lighting.

Standard torch hose length = 1 meter (39"), maximum recommended torch hose length = 2 meter (78")

Chemicals must be obtained from chemical supplier.

Chemicals required: For Aquaflame Model 800 you will need 600gms Potassium Hydroxide Reagent grade crystals, 1.75 liters deionised water and 1 liter MEK (Methyl Ethyl Ketone) in order for Aquaflame to produce gas. The crystals are diluted in deionised water and added to the cell. The MEK is added to the Booster.

Dental Uses:

Dental equipment repairs

Aquaflame machines are often used in dental labs and by orthodontists in construction of dental appliances. Large partial dentures are frequently cast in parts that are soldered together after carefully fitting them to master cast. In orthodontics soldering is used for joining wires, bands springs etc. The soldering process involves the substrate or the parent metals to be joined, soldering filler metal (usually called solder), a flux, and a heat source – in this case the Aquaflame machine. All are equally important and the role of each must be taken in to consideration to solder metal components successfully.

Aquaflame is well suited for dental soldering because it provides a very hot precision hot flame. The use of MEK makes the flame highly visible so that it is easy to view the smallest of solder joints. The use of different booster liquids can vary the flame temperature from 1200-3300°C (2200°F – 6000°F). MEK is normally used because it gives the most stable flame and generates a temperature of about 1850°C. Composition of alloy determines the oxides that form on its surface during heating. The flux used should be able to reduce these oxides, inhibit further oxidation and facilitate its removal. Composition of alloy determines the wettability of the substrate by the molten solder alloy. The solder chosen must wet the metal at as low a contact angle as possible to ensure wetting of the joint area.

Manufacturer of the alloy should provide guidance and instruction regarding the flux to be used with that alloy. A low temp soldering is preferred rather than the high temp soldering for Stainless steel wire to prevent carbide precipitation and to prevent an excessive softening of the wire. So silver solders are generally preferred.

Purpose of flux is to remove any oxide coating on the substrate metal surface when the filler metal is fluid and ready to flow into place. They protect the alloy surface from oxidation during soldering and dissolve metallic oxides as they are formed. The resulting solution of oxides or other extraneous matter in flux constitutes “slag”.

Aquaflame produces an oxyhydrogen flame by electrolysis – the gas is produced on demand and at low pressure. The machine is small, low capital cost and low maintenance. Aquaflame machines are high performance oxyhydrogen gas-generating units producing a high temperature precision flame – in the range 1200-3300°C (2200°F – 6000°F) used for soldering and welding items.

Using a standard electrical supply, hydrogen and oxygen are produced by the electrolysis of distilled water such that the hydrogen can be burnt in the oxygen.

The oxyhydrogen gas is passed through an MEK (Methyl Ethyl Ketone) solution which reduces the temperature to about 1850°C (3350°F) and transforms the flame to a blue / yellow color. The flame is a highly controllable, efficient high energy heat source. The only product of this process, other than energy, is water.

The Aquaflame is safe as it only produces gas as required; it is also efficient, clean and environmentally friendly. Aquaflame is truly a remarkable soldering /welding machine.

Aquaflame is also referred to as a water torch, micro weld (microweld), mini welder, Micro Flame, Aqua torch, Hydroflame. Hydrogem, Jewel Flame, Klein Weld.
