LIGHTING TORCH
OPERATION
NOTICE
The following instructions are for acetylene gas use only. Contact your gas supplier
for instructions on the use of other fuel gases.
WARNING
Before lighting the torch, follow all personal and equipment safety regulations.
Wear filtered protective eyewear (shade 5 minimum) to protect the eyes from
heat, sparks and hazardous UV rays produced by the flame. Keep work area
well ventilated.
BACKFIRE AND FLASHBACK
When the flame goes out with a loud pop, it is called a backfire. Backfire can be caused by (1) operating the torch
at lower pressures than required for the tip used, (2) touching the tip against the work, (3) overheating tip, or (4) an
obstruction in the tip. If backfire occurs, shut off the torch handle valves (oxygen first) and after remedying the cause,
relight the torch.
A flashback is a condition that results when the flame flashes back into the torch and burns inside with a shrill hissing
or squealing noise. If flashback occurs, close the torch handle valves (oxygen first) IMMEDIATELY. Flashback generally
indicates a problem that should be fixed. A clogged tip, improper functioning of the valves, or incorrect acetylene/
oxygen pressure could lead to flashback.
Be certain to find the cause before relighting the torch.
