Troubleshooting
• Bring the flame closer to the piece you're going to cut.
• Place the tip of the preheat dart on top of the material.
• Heat the material up to the "bright red".
• Slowly press the oxygen lever to start the cut.
• Move the nozzle of the torch in the direction required for
the cut.
In the case of handles, open the oxygen
valve completely for better performance.
To cut
• Close the oxygen valve on the torch.
• Close the acetylene valve on the torch.
• Close the valves on both cylinders.

close the valve.
• Release the gauge handles by turning them
counterclockwise.
