Remember, your torch will be burning oxygen and propane or natural gas. Do not use torch components designed for use with air. Pre-mix torches as a rule are capable of burning a little hotter with a flame that can be very concentrated. Gas and oxygen are mixed in a chamber within the torch body.
If you were to be restricted to using only one torch, the pre-mix is recommended. Premix torches have the benefit of having interchangeable tips, allowing the user the option of changing flame characteristics over a broad range. A torch used quite extensively in the industry is the National Handtorch Type 3A Blowpipe shown here. This relatively inexpensive torch, with tip sizes 2, 3, 4,and 5 will cover most of your needs.
Surface-mix torches and burners are used most frequently when large areas of glass need to be worked. Oxygen and fuel gases are mixed at the torch tip. The flame characteristics tend to be broader and softer, with less velocity than a comparable sized flame from the pre-mix torch.
This is a good torch to use when preheating a large piece of glass apparatus for repair, or when shaping large tubing. An excellent example of a burner that incorporates surface-mix and pre-mix capabilities would be the Carlisle CC Burner. There are many other makes and models of burners and torches available to the glassblower. Their different flame and body characteristics determine their application in the glassblowing field.
Torches handheld may be used as burners by simply hanging or attaching them to some sort of fixture. This fixture may be something as simple as a ring-stand and clamp assembly or a custom made unit that will hold the torch in a safe and secure manner.
Before you start Handle the tools you will be using. Review all safety procedures before you plan or start your work. Think out what it is that you will be doing and know what action to take if something happens different than expected. Read through the instruction text to prepare for the exercise. It is best to avoid surprises at this stage of instruction!
In the following discussion, we will assume that you are using a National Handtorch with a 3 tip. It is just a fraction wider and longer than your middle finger. This superbly balanced torch with a rugged aluminum alloy body weighs only 1. The Little Torch features a thin, extremely lightweight hose which provides added maneuverability.
In short, The Little Torch is designed to meet the most exacting industrial standards for a small, multi-purpose torch. The Little Torch has unmatched flexibility -- it can be used with several fuels including acetylene, hydrogen, propane, propylene, MAPP, or natural gas.
It produces a perfectly controlled, completely stable flame hot enough to melt commercially weldable metals, glass and even ceramics. It may also be used with special heating tips to melt up to 3 oz. The Little Torch has a wide range of flame lengths and heat output for various metals and thicknesses. The Little Torch has many engineered-in safety features.
Color coded hoses and valves help prevent errors in setup and operation. Over 80 years of Smith experience in the manufacturing of welding equipment gives you assurance of quality and satisfaction.

The triple mix torch design surrounds each fuel jet with oxygen and has an independently controllable oxygen injector that shoots oxygen in the middle of the fuel stream. This allows more fuel to be burned cleanly, resulting in more heat per jet than normal torches.
This design is also extremely efficient on fuel and oxygen usage. Even though there are more oxygen valves, the oxygen is used to its full potential to mix with the fuel for a very clean hot flame.
This is why the flame characteristics of a GTT torch are superior to other torch flames. The triple mix technology makes flame adjustability easy with no tips to change and no other torches to buy to get the flame types needed for different glass working styles or types of glass. By running the red and green valves with a little blue valve will result in a large blowing flame that is gentle on soft glass and hot enough for any boro work.
Using more of the blue valve will result in a very tight shoulder for precise heating and a penetrating flame. This flame is capable of melting boro similar to soft glass because the heat penetrates to the center of the work.
On the Lynx torch or the center fire of 2 or 3 stage torches, the red and blue valves may be run to get a small, pinpoint flame for the utmost in detail work. This is the smallest flame available from any torch on the market. The triple mix technology is capable of imitating premix flames with the safety of the surface mix design. Combining safety, efficiency, and adjustability along with outstanding flame characteristics, triple mix technology is the heat wave of the future.
These torches burn cleaner and have more flame characteristics than any other torch on the market today. GTT Mirage Torch The Mirage torch is a 2 stage torch that uses the powerful Lynx 7 Jet for the center fire and 2 rings of jets with a total of 33 jets for the outer fire.
Carlisle Bench Burners In , Carlisle was primarily manufacturing gas burner equipment. Carlisle HellCat Torch The Carlisle Hellcat is a totally surface mixed 4 inlet burner that offers a high level of versatility in the flame.
This allows the burner to have excellent positioning capabilities. Specifications Consumption based on standard usage is approximately 1. With both inner and out fires, 4. Features Two options for the centerfire tip. The Ball and Post base utilizes a crescent shaped solid steel base with a ball and socket connection. This style offers a selective articulation. In order to adjust the angle of the head, the user releases a thumb screw at the base of the post.
When re-tightened, this provides positive burner positioning. The user can adjust a knob on the side of the mounting device for quick, accurate positioning. Manufactured from aluminum, the Heat Exchanger dissipates heat from the burner body. The Heat Exchanger has cooling fins providing increased surface area for the transfer of heat.
