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
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.
