Uniweld FV600 fuel valve adapter is used to connect a Uniweld MC acetylene regulator (CGA200) to a disposable fuel cylinder (CGA600). All Uniweld acetylene regulator diaphragms and seals are compatible for use with propylene, Zapp Gas or propane fuel gas. Warning: Fuel compatibility with other manufacturers acetylene regulators must be determined prior to use. The Uniweld 71 welding handle and Type17 weld/braze tips will work properly using either of the fuel gases combined with oxygen. The CA550 cutting attachment will also work with wither fuel gas. However, the cutting tip is fuel specific and must be changed. Also, Uniwelds Capn Hook tips are fuel specific. It is recommended to use grade T hose (part# H32AT) with propylene, Zapp Gas or propane fuel gas. If using grade R hose (part# H32A) with propylene, Zapp Gas or propane fuel gas, it must never be used in extremely cold temperatures below 10 degrees F. This may cause the fuel gas to liquefy and act as a solvent that will attack the internal hose material. Always bleed off the remaining fuel gas in the hose after each use. NOTE: There will be a noticeable performance and temperature difference when using propylene, Zapp Gas versus acetylene and an increase in oxygen consumption. Acetylene burns at 5589 degrees F with an oxy/fuel ratio of 11 respectively. Zapp Gas burns at 5193 degrees F with an oxy/fuel ratio of 3.5 1. Propane burns at 4579 degrees F with an oxy/fuel ratio of 4 1. It is highly recommended to use a Type173 or larger tip for brazing 3/8 and 7/8 copper line sets.
