This manual details the basic operational guidelines for using the TJ-70 Mini ThermoJet
handpiece. A detailed Operation & Maintenance Manual For Accessories (P/N 5050-

0350) is available from PACE.

CAPABILITIES

The TJ-70 Mini ThermoJet Handpiece provides safe, continuous flow of precision
focused hot air for component installation and SMT land preparation. It is primarily
an installation tool and can be used for hot air installation of most surface mount
components. Its slim-line, pencil grip design and finger actuated control switch
facilitates ease of use and manipulation in tight places. The TJ-70 is a member of the
PACE SensaTemp family of advanced handpieces.

CAUTION

Always return heated handpieces to the appropriate Hot Cubby when not
in actual use. Failure to do so may cause burns to the operator, equipment
or work surfaces, and may be a potential ignition source if combustible
materials are nearby. Always use this handpiece in a well ventilated area
to avoid inhalation of fumes created by solder flux gases.

HANDPIECE SETUP

Connect the handpiece power cable plug to one of the handpiece power receptacles
on your PACE power source. PACE recommends that air handpieces utilize the power
receptacles closest to the SNAP-VAC and Controllable PRESSURE Ports to minimize
cord tangles. Connect an Air Hose to the TJ-70 using the method listed below.
Determine the proper tip to install and install the tip in the method listed under “Tip
Installation”.

NOTE

If using your TJ-70 Mini ThermoJet Handpiece for the first time or if you have
just replaced the heater, we recommend that you follow the “TJ-70 Heater
Burn-in” procedure (Red tag on handpiece) to increase the life expectancy
of the heater and to minimize any smoke and fumes generated by the heater
on its initial power-up.

AIR HOSE CONNECTION

The Traditional Method of attaching the Air Hose from the power source is best
suited for use with the TJ-70.

NOTE

Ensure that no Air Hose is connected to the SNAP-VAC Port when using
the TJ-70 handpiece. The TJ-70 Air Hose must be connected to the
Controllable PRESSURE Port. Attachment to both ports simultaneously
will cause a deterioration of performance.

TRADITIONAL CONNECTION

1. Connect the 137cm (54 inch)
length of Air Hose to the metal
tube in the back of the
handpiece.

2. Insert the ridged end of a male
quick connect hose mount
fitting (P/N 1259-0087) into the
free end of the 137cm (54 inch)
length of Air Hose.

3. Secure the Air Hose to the
cable assembly with cable clips (P/N 1321-0085-01).

4. Attach the remaining end of the 137cm (54 inch) length of Air Hose (with
attached male fitting) to the power source Controllable PRESSURE Port.

5. To avoid confusion among handpieces, PACE recommends the use of
colored markers (P/N 6993-0136 Cable Marker Kit) to identify the Air Hose
connected to the handpiece. Attach any two like colored markers, one to
each end of the Mini ThermoJet Air Hose. Any Air Hose attached to
another handpiece should contain markers of another color.
