5. Longer pieces may also require additional penetration gap, VICTOR ®
recommends 1/16" - 1/8".
6. Hold the torch nozzle at an angle of approximately 45 ° to the
joint.
7. Move the torch nozzle over the starting edges of the joint. Rotate
the flame near the metal in a circular or semicircular motion until
the base metals run into a small puddle.
8. Dip the end of the filler rod in and out of the molten puddle, this
melts the rod and adds to the puddle.
9. Continue the dipping motion of the filler rod into the puddle. Then
move the torch back and forth across the joint.
10. Advance the torch nozzle at a rate of approximately 1/16" of the
filler rod as it is added to the puddle until the end of the joint is
achieved.

1. Shut off the torch oxygen valve. Then, shut off the torch fuel valve.
Be careful not to shut off the fuel valve first; this may create a “pop”
type sound. When the “pop” happens it throws carbon soot back
into the torch and may in time partially clog gas passages and the
flashback arrestors.
2. Close both cylinder valves.
3. Open the torch handle oxygen valve. Release the pressure from
the system and then close the torch oxygen valve.
4. Turn the adjusting screw on the oxygen regulator counterclockwise
to release all spring pressure.
5. Open the torch handle fuel valve and release the pressure from the
system. Close the torch fuel valve.
6. Turn the adjusting screw on the fuel gas regulator counterclockwise
to release all spring pressure.
7. Check the inlet gauges after a few minutes to ensure the cylinder
valves are turned off completely and there is no pressure remaining
in the system.
