The German Micro Welding torches are designed for professional jewellery manufacture and repair, dental laboratories, optical and electronic industries, hobby, craft, plumbing, refrigeration & glasswork.
The Micro Welding Torch features an extremely precise flame with fine control.
- The handheld blowpipe can be used with all types of fuel gases: MAPP / Razor gas, Acetylene, Hydrogen or LP Gas in combination with Oxygen.
- Due to its construction and the use of high pressure hoses it accepts oxygen pressures from 80 KPa up to 400KPa and can produce high temperatures e.g. reaches about 2600°C, when used with oxygen & LP Gas. It is very reliable, easy to use and offers remarkable Long Life of well-known German quality workmanship.
- Great for demanding application, delicate
soldering (retipping prongs), heavy silver
work,
welding and melting.
designed for easy and
quick tip change
without spanner - just push on.

For
the German Micro Welding Torch you need one fuel gas regulator (e.g. LP Gas)
plus flashback arrestor and one Oxygen regulator plus flashback arrestor. You
will have a separate connection hose for each
bottled gas. The gas bottles can usually be hired from local gas suppliers.

Micro Welding Torch Advantages & Safety features:
- 2 Goose necks with rubber seals.
- durable and flexible High-pressure hoses allow for variable Oxygen pressure 80 KPa - 400 KPa (offering higher temperatures) with 5/8-18UNF connections to fit onto flashback arrestors
- Easy tip change, no tools required, simply push on.
- Change to second goose neck (for use of 3 bigger rosebud brass tips of 12mm length for melting and heavy duty work) without spanner, only to change brass tips themselves spanner required.
- Very precise, accurate and steady flame, perfect for soldering on delicate spots as well as large areas and melting.
- The Micro Welding Torch can be used over long time periods with minimal hand fatigue due to the comfortable size and weight.
- Twelve tips in different sizes offer flames from accurate pinpoint to hissing for high heat & fast melting jobs.
Gas usage of the Micro Welding Jeweler's Torch is as
follows: The push-on steel tips for fine work are numbered from 18 to
26, from largest to smallest.

How to set up and operate your Micro Welding Torch
Fuel fittings are LH = left-hand and tighten to the left. They are standard-marked with a groove on the screw nut.
Oxygen fittings are RH = right-hand and tighten to the right. They are standard-marked with a smooth screw nut (no notching).
- Connect the blue hose via flashback fuse to the oxygen regulator. Tighten with a spanner. Never bring any oxygen equipment in contact with grease or oil! Danger of explosion.
- Connect the red hose via flashback fuse to the fuel gas regulator. Tighten with a spanner.
- Check for gas leaks by applying water with dishwashing liquid in it around all new connections.
- Shut at the Micro welding torch the oxygen and the fuel gas valve.
- Attach the required tip to your Micro welding jeweller's torch.
- Open valve at oxygen cylinder and set the pressure between 80KPa and 400KPa (0.8bar to 4 bar, 11.6PSI to 58PSI), depending on the type of work and tip used. When using the large goose neck and tips, increase the oxygen pressure to at least 150KPa to prevent heat build-up in the goose neck. Do not increase LP Gas Pressure.
- Open valve at fuel gas e.g. LP Gas cylinder and set the pressure at 80KPa (0.8bar, 11.6PSI).
- Only, if you are working with Acetylene Gas: Open the blue oxygen valve at the Micro welding torch slightly, otherwise leave it tightly closed.
- Open the red fuel gas valve at the jewelry torch and ignite.
- Carefully adjust the flame by feeding in oxygen and start working.
- Always shut first the blue oxygen valve at the torch and then the red fuel gas valve at the torch.
- Before leaving the workshop shut the oxygen cylinder valve and the fuel gas cylinder valve.
- Purge all fuel and oxygen lines after daily use to ensure no gases remain in the torch system. Top of page
