High Pressure Natural Gas Is The Best Fuel For Jewelry Manufacturing

Superior Torch Performance - Lowest Cost Fuel Cleanest Flame - Safer Workplace

High pressure natural gas is hot enough to melt and cast platinum! Platinum melts at 3,300F and by boosting natural gas pressure to 10-15 psi you will get plenty of heat for high-quality casting results.


Natural gas burns at more than 5,000F but you need plenty of gas volume to put the maximum heat on the metal. Higher pressure means more gas flow and better heat transfer to platinum and all karats of gold.


Platinum casters report better results when heating with natural gas; there is less stress on the metal, less porosity and an overall better quality cast.

Your workplace is safer with high pressure natural gas. When you bring a cylinder of fuel gas into your studio you introduce a lot of stored energy that could be very dangerous. One BTU is the equivalent of lighting one wooden kitchen match so if you use a 1-pound propane tank that would be like having a box with more than 21,500 matches. A small “B Tank” of acetylene is the equivalent of more than 58,000 matches. If you have a 20 lb BBQ propane tank it would be like having more than 431,000 matches in a pile in your studio.


A G-TEC Torch Booster eliminates stored gas by boosting natural gas pressure as it is used at the torch - there are no cylinders or stored gas.



High pressure natural gas makes OSHA-required flashback arrestors practical. If your torch is connected to the utility natural gas pipe OSHA and local fire codes require you to use combination flashback arrestor check valves to protect the gas meter from a torch flashback.


The problem is that flashback arrestor check valves need at least ¾ psi gas pressure to work properly, otherwise they block gas flow.


With high pressure natural gas from a G-TEC Torch Booster there is enough pressure to make the flashback arrestor check valve work properly, and still provide a robust flame on the torch.


When a jeweler’s torch has a flashback a 5,000F flame travels through the hose and gas pipe to the gas meter, which explodes.


The explosion can send pieces of the meter flying in all directions, injuring anyone standing nearby and

starting a fire.

If you are using natural gas right from the city utility gas pipe your torch is not getting all the gas pressure it needs for top performance.


Utility natural gas pressure is only ¼ psi in most places but your torch is designed to work best at pressures between 3-7 psi. While you can light the torch with city gas service manufacturers recommend higher natural gas pressure when it is available. It is like the difference between cutting with a sharp knife compared to a dull knife.


You may also experience a flickering or unsteady flame, especially in winter, as heaters and other gas appliances in your building turn on and off. High pressure natural gas supplied by a G-TEC Torch Booster smoothes out gas flow so you work with a steady, reliable torch flame.


Get the best performance your torch has to offer by using high-pressure natural gas!



For equal BTUs high pressure natural gas is half the cost of acetylene or propane. Plus you don’t have pay an expensive monthly cylinder rental cost or waste time ordering, storing and changing empty fuel gas cylinders. Never lose productive time by running out of gas or paying extra for an emergency delivery.

Natural gas is much cleaner than acetylene and propane because it has very little carbon in the flame. This means no soot as when you light an acetylene torch and no carbon buildup on the torch tip. Natural gas is also greener than acetylene and propane - the carbon footprint from natural gas is 25% less than acetylene, 15% less than propane for equal BTUs.
