FXD 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.WELDING
FXD 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 FXD so superior for most metal-working purposes disqualify it for steel-to-steel welding.CUTTING
Not only does Flamex 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.GOUGING
FXD 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.FLAME HARDENING
The higher temperature of Flamex 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 FXD flame, it does not require the skill demanded of an operator working with acetylene. An inexperienced operator can do excellent work with Flamex treated gases.POWDER CUTTING
All of the advantages that FXD offers in ordinary flame cutting are present in powder cutting operations. One leading manufacturer of powder cutting equipment reports that FXD treated gas is 10 to 20 percent faster than the next fastest gas on the market.
