Dear Mr. KilBane:

    I am with a firm which manufacturers a larger, multicell unit
    (www.spirig.com) but can answer your questions. The following
    booster fluids can be safely used and will produce the temperatures
    listed. 

    Pure Hydrogen / Oxygen = 3,300 degrees C or 5,972 degrees F.
    Methanol = 2,700 degrees C or 4,892 degrees F.
    Isopropanol = 2,500 degrees C or 4,532 degrees F.
    M. E. K. = 1,700 degrees C or 3,092 degrees F.
    Acetone = 1,500 degrees C or 2,732 degrees F.

    These booster fluids are totally consumed within the flame. The
    cooler the flame the wider, and softer, "bushier" the flame will be.
    If you wanted to use just Hydrogen/Oxygen gas you would have to run
    water in the booster system to protect against flashbacks, although
    not all water welder booster fluid systems are designed as redundant
    flashback systems so you would have to contact your units mfg. for
    their specific advise. For servicing, which I believe is twice a year
    for this unit, but you can do yourself, please contact: 

    Microweld, 39 Bute Street, Eccles, Salford, Lancashire, M50 1DU, UK. 

    If we can be of any additional help or answer any other questions
    within this area, please feel free to contact me directly at any of
    the contact points listed below. 

Best Regards,
Gary
