USING THE WORKRITE ELECTRONIC HAND UNIT
The WorkRite Electronic hand unit has been designed to
be rugged, lightweight, and versatile. Its
primary function is applying the electronic energy to the glue joint.
The inside of the hand unit consists of a large coil of many turns with a
larger single link coil around it. This
inside 14-turn coil is called the "Tuning Coil".
The single outside coil is the "Pickup Coil".
THE "TUNING COIL" AND THE "PICKUP COIL" SHOULD NOT
TOUCH EACH OTHER OR ARCHING WILL OCCUR.
There are six metal plates inside the hand unit.
Two of these plates are stationary and four are movable.
Moving the thumb-tuning lever forward or backward achieves high heat
ranges shown on the milli-amp meter. This
is similar to tuning in a radio station on your radio.
Moving the thumb-tuning lever on the hand unit allows
the operator to change from one size project to another quickly and at the same
time, be assured of maximum heat. Whenever
you change from one type of material to another, the material width varies, or
the amount of glue used changes, the tuning lever must be moved to compensate
for the change in load. Moving the thumb lever is necessary for each weld. This will
continue to give you the highest heat possible.
To attain high heat on wider projects, position feet
with a wider space between them (farther apart from each other). The small
electrode feet will attain high heat on wider projects because they are farther
apart from each other. In some cases using one small and one flat electrode will
give best results.
a narrow piece of wood under the electrode feet will generally
help to tune in higher heat. The
energy will penetrate through 2 1/2 inches. Do not allow arcing at glue line.
The electrode feet DO NOT have to touch or come
in contact with your project or the glue line to
The heat zone is between the electrode feet.
Maximum tuning can be obtained by spacing the electrode
feet farther apart.
Experiment with the electrode feet in different gap
positions using the position that offers the most
electronic heat into the joint to be set.
Usually the widest position should be used
on wide heavy boards, and the narrow position on
small narrow boards.
Electrode feet should always be placed perpendicular (across)
the glue line.
Always try to keep the panel meter at a medium to high
Maximum heat is indicated in two ways: the panel meter,

When either the panel meter or the glow lamp is at
their maximum, you are now receiving the greatest
amount of electronic heat.

job, to try the above application steps with two
scraps of wood.
