Natural gas brazing flame is hot but with more control Brazing copper pipe at Plumber Local 501

When the United Association of Plumbers Local 501 near Chicago switched from acetylene to hi-pressure natural gas to teach medical gas and refrigeration brazing, their apprentices started passing their exams 25% sooner!

Mike Lang, Welding Director explains why UA Local 501 switched from acetylene to hi-pressure natural gas for brazing training.

Why natural gas is better than acetylene for brazing

Natural gas has a bulbous flame that has more heat in the secondary flame than acetylene - it wraps the work and distributes heat more evenly around the joint

More even heating reduces the potential for oxidation defects

Fewer melt-throughs and base metal heat related defects

Braze rod flows more smoothly and fills more completely

Little free carbon in natural gas reduces “fisheye” defects

Less porous brazes

Brazers say a natural gas flame is softer and easier to control



When you switch to high pressure natural gas for brazing keep the torch handle you already have and use a G-TEC mixer, gooseneck and tip combination. G-TEC tips are modular allowing you to mix an assortment of gooseneck lengths and many sizes of single flame and multi flame tips.

G-TEC brazing tips are modular, allowing you to mix gooseneck lengths and single or multi flame tip sizes for the right fit for your job!

A natural gas flame wraps the entire joint for even heating and a better braze.

G-TEC Torch Boosters connect to a standard utility gas line and boost pressure as high as 45 psi. Just turn the Torch Booster ON at the start of the first shift and OFF at the end of the day - you get an endless supply of high-pressure natural gas for your brazing torches. Torch Boosters deliver gas in exactly the same way as a cylinder or bulk tank,except that you save money and never run out!

Pick The Right Torch Booster For Your Shop

TB-30 - For shops with one oxy-fuel torch TB-30 boosts utility gas pressure to 25 psi at 30 cf/hr and will operate one oxy-fuel brazing torch. TB-30 measures only 12’ wide and 12” tall with a depth of 16” and is easy to install almost anywhere.

TB-60 - For shops with 2 oxy-fuel torches TB-60 Torch Boosters supply high-pressure natural gas at 60 cf/hr - enough for 2 brazing torches

TB-125 - For shops with 3 or 4 torches T B-125 boosts pressure to 25 psi  and delivers 125 cf/hr - enough gas for 4 brazing torches

TB-60 and TB-125 Torch Boosters are in cabinets that measure 20” wide, 16” tall and 18” deep,about the size of a window air conditioner.

TB-250 - When your shop has up to 6 torches TB-250 can boost gas pressure as high as 45 psi and deliver enough gas to run 6 brazing torches at once. Install a regulator to set get pressure between 1-45 psi.

TB-500 - When your shop has up to 12 torches TB-500 is our biggest Torch Booster and can boost pressure to 45 psi at 500 cf/hr, enough to supply 12 brazing torches at once. Install a regulator to set gas pressure between 1-45 psi.

TB-250 and 500 systems measure 28” wide, 20” tall and 24” deep.

Do you have more than 12 brazing torches or multiple production stations in your shop? Good news! Torch Boosters can be connected to a gas manifold to supply multiple cutting tables or production areas, and if you have more than 12 torches in your facility, multiple Torch Booster modules can be connected together. Based on your torch cutting requirements G-TEC will design the right combination of Torch Boosters for you!
