Frequently Asked Questions

Q. Benefits - What are FXD's advantages?

A. FXD 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. FXD gives greater advantages for aluminum, brass, and cast iron welding, brazing and silver soldering by extremely clean burning. FXD does not have any free carbon in the preheat flame and does not blow back in the torch.

Q. Cost Savings - What are the cost savings when using FXD?

A. No special carrier tanks are needed, reduced storage area, no dip tubes, no circulating pumps in bulk storage tanks, no scales and no residual is left in the tank. Labor cost and oxygen cost are reduced due to the increased performance when using FXD.

Q. Disadvantages - What are the disadvantages of FXD?

A. FXD will not weld mild steel to steel because of the absence of free carbon in the preheat flame.

Q. Equipment Change - Are any changes in the welding or cutting equipment required?

A. Yes, changing to propane style welding tips and cutting tips to allow for proper flow.

Q. Faster Cut - Why does FXD cut faster?

A. FXD 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.

Q. Flame Adjustment - How is the preheat flame adjusted properly?

A. For any given amount of preheat gas, you simply add enough preheat oxygen to bring the inner cone to its shortest, deep blue point. Any additional preheat oxygen will make the inner cone light blue and more transparent thereby cooling the preheat flame.

Q. Guarantee - Is FXD guaranteed?

A. Yes, a 100% guarantee. Each formulation of FXD is tested to conform to our own strict quality requirements.

Q. Hotter Flame - What does hotter flame mean?

A. The hotter flame means complete oxidation and better heat transfer. This is made possible by a breakthrough enabling suppression of radiant energy, thereby causing higher temperature in the primary flame.

Q. Ingredients - What are FXD's ingredients?

A. FXD is a blend of liquid hydrocarbons. Please refer to the material safety data sheet for more information.

Q. Natural Gas - How can FXD be used with natural gas or propane vapor?

A. A blending system treats the natural or propane gas vapor as it flows through the pipe distribution system. Flamex Industries provides the technical support and detailed instructions for the blending system.

Q. Primary Use - What are the primary uses for FXD?

A. Welding, flame cutting, gouging, heat treating, hard surfacing, flame hardening and brazing.

Q. Safety - How safe is FXD?

A. FXD is extremely stable. Full tank pressure can be used if needed.

Q. Tanks - What type of tanks are required?

A. Propane tanks for propane based FXD or propylene for propylene based FXD. The product can also be used for bulk tank systems.

Q. Temperature - Does cold weather affect the performance of FXD?

A. No, FXD remains completely homogeneous under any temperature. It does not stratify or separate as other additives can.

Q. Treatment - How much FXD do I use?

A. One ounce of FXD treats ten gallons of propane or propylene. Please see sheet on natural gas for mixture ratio.

Q. Withdrawal - Does heavy withdrawal affect the performance of FXD?

A. No.
