Tulsa Gas & Gear offers fuel gas that combines propane with an additive to give you a higher flame temperature than just propane by itself. Fuel gas is a more stable gas than acetylene resulting in a higher level of safety. Fuel gas produces a hotter flame and faster piercing and is a more economical cutting fuel than acetylene and will result in less use of oxygen and fuel.
Fuel Gas gives a quicker start time due to concentrated high temperature, 5-10% faster cutting speeds on straight cutting plus 10-20% faster cutting speeds on shape cutting. Fuel Gas gives greater advantages for aluminum, brass, and cast iron welding, brazing and silver soldering by extremely clean burning. Fuel Gas does not have any free carbon in the preheat flame and does not blow back in the torch.
Fuel Gas increases the flame temperature to 5900 F + (3,260 C +) and concentrates its focal point on the steel. This brings the leading edge of the cut up to its kindling point more rapidly.
Fuel Gas does a superior job in brazing. There is nothing present in the flame which would tend to produce a porous bond. In brazing copper to copper, using flux, the surface of the heated metal becomes clean and shiny, so much that there is no need for any finish with wire brushes or grit paper.
Fuel Gas is excellent for welding of aluminum, copper, cast iron and brass. It's also superior for braze welding of steel. Paradoxically, the characteristics that make Fuel Gas so superior for most metal-working purposes disqualify it for steel-to-steel welding.
Not only does Fuel Gas treated gases cut steel faster than other gases, they do it with less slag and no weld-back because of the complete oxidation that takes place in the hotter flame. There is little or no finish grinding or costly clean-up necessary after cutting.
Fuel Gas increases the speed and quality of gouging operations dramatically, producing a trough in which the parent metal is exposed, almost totally free of slag or weld-back, and ready for welding.
The higher temperature of Fuel Gas and its superior heat transfer properties, plus the fact that its stability permits greater line pressure for an enlarged flame, result in faster flame hardening at reduced cost. And because there's more heat in the secondary Fuel Gas flame, it does not require the skill demanded of an operator working with acetylene. An inexperienced operator can do excellent work with Fuel Gas treated gases.
All of the advantages that Fuel Gas offers in ordinary flame cutting are present in powder cutting operations. One leading manufacturer of powder cutting equipment reports that Fuel Gas treated gas is 10 to 20 percent faster than the next fastest gas on the market.
