CAUTION
Always make sure your equipment is rated for the size tip you have selected. A tip with too
much capacity for the equipment can starve or choke the tip. This causes overheating of
the head and a backfire may result. Use only genuine VICTOR

tips, welding nozzles and multi-flame nozzles to ensure leak-free connections and
balanced equipment.

Figure 6: Cutting Tip (1-1-101)
Tapered Seating Surfaces
The tapered end of the tip is machined to fit into the cutting attachment head. A tip nut secures the
tip into the head. The tapered surfaces form a metal-to metal seal (see Figure 6). Inspect both the
head and tip tapers frequently for signs of damage or wear.
WARNING
A damaged seating surface on either the tip or the head can create a hazardous condition,
resulting in a backfire or sustained backfire. This may damage the cutting attachment.
If the seating surface of a tip becomes damaged, DO NOT use it. Discard the damaged
tip. If the head requires repair, take the torch to a qualified repair technician.
Preheat Orifices and Oxygen Orifices
Cutting tips are subjected to much abuse in cutting operations. Slag can splatter and stick to the
cutting tip, clogging or obstructing the passages through which the gas must flow. Remove splatter
from the tip orifices with appropriate tip cleaners.
NOTE
Repeated cleaning can affect the flame configuration and render the tip unsuitable for
precision work.
