0 Introduction
The PG-18 heating welder is a device that welds thermoplastic round belts. Ends are joined by chamfer
welding: the ends of the belt are melted, pressing them against a precision-regulated hot welding plate.
After being suitably heated, the ends are pressed against each other with a set pressure and left to cool.
After the burr on the tip of the joint is removed with a blade or rectified, an excellent quality round belt is
obtained.
The PQ-18 welder is suited for on-site installation or for medium/small mass production in a workshop.
PQ-18 is used indistinctively to indicate models:
PQ-18/6 for 120 V power voltage
PQ-18/8 for 230 V power voltage

4 Operating mode
The heating power and the output control of the welder [2], in combination with the heating plate [1], are
optimally adapted to the energy requirement for butt-end welding of thermoplastic round belts.
The design of the guide heads [11] on the guiding tongs [5], which is adjustable in 3 positions makes it
possible to join the ends of thermoplastic round belts under approximately optimum joining pressures. The
label on the guiding tongs [5] indicates the spring position for the relevant thermoplastic round belt diameter..
The holding device [6] facilitates handling. With a corresponding number of guiding tongs [5] and holding
devices [6], efficient production in series is possible.
5 Getting started
Make sure the voltage specified in chapter “TECHNICAL SPECIFICATIONS” corresponds to connected
mains voltage
A tool marked 230 V can also be connected to the 220 V mains.
Similarly, for the 120 V version, 110 V power is tolerated.
Clamp holding device [6] to work table by means of clamping screw [7].
Place guiding tongs [5] on Holding device.
Check parallel adjustment of welding plate to flat support area of handle of welder [2]. When laid
down on a table, the welding plate may not touch the supporting table.
Make sure the voltage specified on the rating plate corresponds to connected mains voltage.
Make sure the heating plate [1] are clean.
Connect the welder [2] to mains and place it on a sufficiently flat surface. Respect preheating time of
15 min.
Check temperature of the heating plate. The temperature is preset at the factory at 250 °C / 482 °F.
WARNING
Do not touch the hot zone!
Keep device away from water and meltable substances.
Do not suspend the welder [2] from its cable with the heating plate [1] swinging. The
heat rising from the heating plate [1] may destroy the welder [2] electronic regulator.. If
need be (e.g. when joining a belt in a machine), bend a wire into a support hook, from
which you can hang the welder by the welding plate.

6 Welding of round belts
Procedure: refer to the Habasit Polycord joint guide.
Cut thermoplastic round belt to length at right angles with cutting device S-16 (available
accessories). Refer to the Habasit guide to determine belt length
Lock locking spring [3] in appropriate position.
Open guiding tongs [5] and secure them by closing the bracket [4].
Open guide heads [11] by turning the knurled nuts [12].
Introduce belt ends laterally into guide heads [11] and let ends protrude 2÷4 mm / 0,08÷0,16 in.,
depending on diameter (larger diameters to protrude more).
Fix belt ends by turning knurled nuts [12].
INDICATION
Fix belt without twisting, i.e. according to its „inner disposition“!
Introduce welder [2] with heating plate [1] between guide heads 11].
Free securing bracket [4] and carefully close guiding tongs [5].
Let belt ends melt until the bead measures about 1-2 mm / 0,04-0,08 in., depending on belt
diameter.
Then block the handles of the guiding tongs [5], by hand, so that the guiding tongs [5] can not close
any further. This makes the belt ends stay in contact with the heating plate but without pressure
(about 5-10 s, depending on the diameter of the belt). This permits the belt ends to melt to the core
without further enlarging the bead.
WARNING!
Accidental contact between the belt and hot blade surface may generate fumes harmful
to health.
Do not inhale vapours generated during welding. Only weld thermoplastic belts in
suitably aerated rooms!
The installation of suitable exhaust devices and/or personal protection equipment must
be assessed by the user based on work site characteristics and current local laws
Slightly open the guiding tongs [5] by pressing the handles.
Pull out the welder [2] and place it on a flat table. At the same time, carefully close guiding tongs [5]
(joining the two melted sections).
WARNING
Do not touch the hot zone of the welder!
Keep device away from water and meltable substances.
Let joint cool in guiding tongs [5] for about 1-2 min.
Open Guide head [11] by loosening the knurled nuts [12] and remove joined belt.
Open guiding tongs [5] and lock securing bracket [4].
Whenever the welder is not in use, pull out mains plug.
Remove bead with pliers, file or grinding disk.
WARNING
After use, disconnect the welder from the power supply and allow it to cool completely
before storing it.

7 Maintenance
Always keep the welding device clean. Clean the heating plate [1] regularly and remove all material residues.
Clean the heating plate [1] while heated with a cotton cloth.
Unplug the welder from the mains before cleaning with a water or alcohol dampened
cloth.
Burning hazard! Fold cotton cloth in several layers to assure good insulation!. Do not
touch hot surfaces!
Never clean heating plate [1] with hard objects (such as screwdrivers, spatulas etc.)!
This will damage the Teflon coating.
Check guiding tongs [5] for smooth running. If necessary clean and very slightly oil axle pin [9] and guide bar
[10].
Periodically inspect the welder power supply cable and connector plug for defects (insulation damage, etc.)
and rectify or replace with the correct type where necessary.
7.1 Measuring of the plate temperature
Check the operating temperature of the hot-pressing device once a month.
