The Microwelder is a compact, portable gas generator producing an oxygen and hydrogen mixture cheaply from distilled water.

The gas is passed through methyl ethyl ketone to a torch tip to give not only an extremely hot flame – up to 1850°C – but one which is sufficiently clean to ensure that the workpiece is not contaminated. Detachable torch tips are supplied to enable the operator to vary the precise size and direction of the flame for optimum results. Using only a standard electrical supply, the flame polishers high temperature flame is produced from small volumes of gas supplied at low pressure. No storage or compression of gas is therefore necessary and its operation involves no cumbersome cables. Running costs (electricity, distilled water and MEK solvent) amount to only a few pence per day. The Microwelder is supplied complete and ready for use with a range of nozzles for all types of acrylic finishing. Extra nozzles, MEK solvent and replacement spares are readily available.
