OPERATIONAL WARNINGS


• Do not operate the torch with a flame that is less than ¼ inch long because it can overheat the mixing tube and cause
flame outage or flashback.
• Do not hold the tip of the torch too close to the work piece. This can cause the flame to go out, cause flashback and
weld the tip shut.
• Do not operate the torch if the section of the mixing tube that is directly in front of the torch handle becomes hot.
Although the section of the mixing tube immediately behind the tip of the torch can get hot, the section of the mixing
tube directly in front of the handle should never get hot. If this occurs, extinguish the torch immediately by turning OFF
the oxygen valve and then the fuel valve. Allow the torch to cool and then check the tip of the torch for blockage. If the
tip is unblocked and clean, relight the torch. If the section of the mixing tube that is directly in front of the torch handle
still becomes hot, discontinue use of the torch and contact Bernzomatic immediately.
• If the flame disappears unexpectedly, immediately turn OFF the oxygen valve and then the fuel valve. Disconnect the
oxygen and fuel valves from their cylinders and re-open the valves to bleed the hoses.
• Place the cylinder stand on a stable and level surface. Improper stand position, such as placing the stand on its side,
could cause accidental tip over leading to liquid fuel entering the hose and causing an excessively long flame. This is
called flare and is very dangerous. It can also cause the flame to go out.
• DO NOT USE THE TORCH IF THE HOSES SWELL DURING OPERATION. THE HOSES MAY RUPTURE UNEXPECTEDLY AND
CAUSE INJURY OR DAMAGE. If the hoses swell, stop using the torch by turning OFF the oxygen valve first and then the
fuel valve. Disconnect the valves from the cylinders and then re-open the valves to bleed the hoses. Replace the torch
assembly before relighting.
• Always use tools, such as tongs or pliers, to handle brazing/welding rods because they could be hot.
• Beware that certain surfaces can reflect and transfer the heat back to the torch handle causing damage or injuries.
• In cold weather the size of the flame will be smaller.
• Always carry the torch by the handle and make sure the valve side of the cylinders is not tipping downward, which
could cause the cylinders to fall out of the stand.
