Filing the wire to a point, straightening a short section at the end,
or rotating the bore welder spindle may help automatic feeding of
the wire.
Do the following to change torch tips:
1. Loosen the setscrew holding the tip.
2. Remove the tip from the torch body.
3. Insert the new tip into the body and the liner.
4. Hold the torch horizontally so that the tip falls into its seat.
5. Tighten the set screw to prevent movement.
6. Position the tip axially to a
point slightly below center
to the nozzle opening,
using the hex wrench as a
gauge, as shown in (Figure
3-33).

Because the wire is
curved when exiting
the tip, the point of
contact with the work
is higher than might
otherwise be
expected. Therefore,
position the tip
slightly toward the
end of the nozzle.
After rotating torches for setup, centering, or screwing into an extension, jog the
wire through the torch until it exits the tip in a stable condition, producing a clean
spiral of wire. This relieves the torsional stresses built up in the wire (because wire
was not fed while rotating), so that the weld process will not be affected by wire
wandering at startup.
3.4.3 Torch extension support kit
The torch extension support kit is ideal when the distance from the bore welder to
the torch is great enough to make torch stability uncertain and alignment difficult.
