3. Repeat step 2 as many times as necessary to completely clear the line.

THE TIPS GET HOT OR START TO BURN
When the needle tips begin to blacken or turn cherry red at the hot end it is because the
flame is beginning to burn back up into the tip. This will happen for several reasons:
1. The knob on the handpiece has not been opened enough.
Slowly turn the knob on the handpiece counter-clockwise to open the valve more. If the
flame does not immediately get stronger, and the tip continues to burn, check the next
step.
2. Liquid in the hose has entered the handpiece and catches fire as it comes through the
tip.
Disconnect the hose from the rear check valve and the handpiece. Drain any fluid from
the hose. Dry the hose by blowing compressed air through it. Remove the filter from the
back of the handpiece and air dry. Also thoroughly dry the handpiece and the tip.
Reconnect everything and turn the unit on. Open the valve on the handpiece and let the
gas free-flow for 15 seconds before lighting.
3. The torch is shut off before the flame is extinguished at the handpiece.
The gas must first be shut off at the handpiece, before turning the unit off. If the gas is
left on while the unit is turned off, the flame will try to burn back into the tip. This will
singe the end of the tip and can melt the plastic casing on the tip.
4. The electrolyte is contaminated or needs to be changed.
When there is a problem with the electrolyte, gas generation is impaired. The lack of
sufficient pressure causes the flame to draw into the tip, burning the tip. Follow the
instructions for changing the electrolyte.

THE FLAME TAKES ON AN ORANGE COLOR, OR BEGINS TO
OXIDIZE THE SOLDER
An orange flame develops generally from one or more of five causes:
1. Insufficient gas pressure causes the flame to burn backward into the torch tip and burn
the tip. Causes are:
a. Gas leaks or blockages; check all hoses and connections.
b. Dirty filter element; replace filter.
c. Low water level in gas generator; add distilled water.
