If using a vise, grip the tip on the sides with light force. When tightening the vise, use

light force to avoid damaging the solder-in probe head If using a tweezers clamp, grip
the tip either on the sides or at the top and bottom.

To avoid burning and damage to the pc board, do not keep the soldering iron in

contact with the tip any longer than necessary. The solder joint has very low thermal
mass, so the joint quickly melts and releases the wire.
Make sure soldering iron tip is free of excess solder.

Use the vise or clamp to position the tip an inch or so off the work surface for
easy access.
If you need to remove an existing or damaged lead wire, grab each resistor lead
or body with tweezers and pull very gently up. Touch the soldering iron to the
solder joint just long enough for the resistor to come free of the probe head tip.
In needed, fill the mounting hole with solder in preparation for the new wire.
Use the flux pencil to coat the solder joint area with flux.
Prepare the mini-axial lead resistor for attachment to the head's pc board. The
lead to be attached to head's pc board will have a 90° bend to go into through
hole in the tip pc board.
Using tweezers, place the resistor body inside the rectangle of the trim
template.
