ing the square solder post of the PIP pin receptacle
in the retention slot in the split holder and sliding
the assembly up into place. Position the flange on
the PIP pin receptacle flush with the front face of
the split holder.

head. Confirm that the PIP pin assemblies, PIP leads,
and the negative/plasma and pilot leads are prop-
erly positioned.
CAUTION
Do not force the holder together. Damage to the in-
sulation on the leads will cause torch head failure.
The PIP leads must be positioned correctly to allow
reassembly of the torch head.
