You don’t need expensive fuel gases or gas additives for quick pre-weld heating when you have natural gas available from a G-TEC Natural Gas Torch Booster.


A torch fueled with natural gas has a large bulbous flame that actually has more BTUs than acetylene so it is perfect for heating large areas. The bigger the item being heated the better natural gas performs compared to other gases.


Natural gas costs half as much as acetylene and 75% less than propane or propylene. Best of all there are no limits on withdrawal rates (acetylene is limited to 15 psi) and no icing of the cylinder valve that is common with liquid fuel gases.


A G-TEC Torch Booster is directly connected to the utility gas supply so you never run out and don’t have to change cylinders in the middle of a big job!
