d. Low voltage; check line voltage and/or change lines.
e. Deformed torch tip; replace torch tip.
f. Corroded electrical connections; clean connections.
g. Electrical failure; check incoming power source.
2. Flux level low, or chamber empty;
Add Flux.
3. Torch tip dirty;
Clean tips in an ultrasonic or steam cleaner. Replace if necessary.
4. Gas generator overheated and delivering water vapor to the torch tip.
Turn unit off for a few minutes to allow it to cool. Check that the ventilation slots are not
blocked. Check that the fan is still running.

THE TORCH TIP IS SPITTING OR OVERHEATING
Spitting of liquid from a torch tip during operation is often, but not always, associated
with overheating of the gas generator. Possible causes of such overheating are:
1. Distilled water chamber overfilled with distilled water;
2. Too high a line voltage;
3. Contaminated electrolyte;
4. Corroded electrical connections inside the gas generating chamber;
5. High resistance short circuit inside gas generating chamber;
6. Operating environment too hot;
7. Fan failure;
8. Distilled water chamber excessively dirty; and/or
9. Power setting too high.
The first thing to check is the filter chamber. Spitting indicates that excess liquid is in the
line. Check the filter to see if it has become moist and replace if necessary. The gas
generator will generally run pretty hot and a temperature of 160
o
F on the chamber surface
is not unusual. This temperature can be achieved when the gas generator runs
continuously at or near full load conditions. At this temperature the gas generator can be
expected to deliver some water vapor into the lines along with the oxyhydrogen gas.
However, the filter and flux booster will tend to trap this water vapor before it reaches the
torch tip. If the filter is wet and is unable to trap all the moisture, it will pass into the flux
chamber. The GREEN flux supplied by the factory will change in color when it has
trapped significant quantities of water vapor. The change in color indicates that the flux
