power cord to unplug the unit from the socket. Protect
the cables against heat, oil, and cutting edges.
2.3 Securing the Fitting and the Joint
Use positioner clamps or a vice to secure the fitting and
the joint to be made before welding. The fitting manufac-
turer’s installation instructions, local and national regula-
tions have to be respected in all cases.
A welding process must never be repeated with the same
fitting, since this may cause parts under power to be ac-
cessible to the touch.
2.4 Cleaning the Product
The product must not be sprayed with or immersed in
water.
2.5 Opening the Unit
Caution
The cover of the product may be removed only by
specialized staff of the manufacturer or of a service
shop properly trained and approved by it.

To extend power cord length, use exclusively properly ap-
proved extension cables that are labeled as such and have
the following conductor sections:
up to 20 m: 1.5 mm² (2.5 mm² recommended); Type H07RN-F
over 20 m: 2.5 mm² (4.0 mm² recommended); Type H07RN-F
Caution
When using the extension cable, it has always to
be rolled off completely and lie fully extended.
2.7 Checking the Product for Damage
Before every use of the product, check safety features
and possibly existing parts with minor damage for proper
function. Make sure that the push-on connection terminals
work properly, that contact is fully established, and that
the contact surfaces are clean. All parts have to be installed
correctly and properly conform to all conditions in order
for the product to function as intended. Damaged safety

only accessories and spare parts that are recommended or
approved by the manufacturer. Using other parts or acces-
sories may put yourself in danger of bodily injury or cause
the device to malfunction.
2.9 PowerSupplySpecications
2.9.1 Mains Power Supply
Utility suppliers’ wiring requirements, occupational safety
rules, applicable standards, and national codes have to be
respected.
Caution
When using power distributions on the worksite,
rules for the installation of earth-leakage circuit
breakers (RCD) have to be respected, and operation
requires an installed breaker.
Generator or mains power fuse protection should be 16 A
(slow blow). The product has to be protected against rain
and humidity.
2.9.2 Generator Power Supply
The required nominal generator capacity as determined
by the power supply requirement of the largest fitting to
be welded depends on the power supply specifications,
the environment conditions, and the generator type itself
including its control/regulation characteristics.
Nominal output power of a generator 1-phase, 220 - 240V,
50/60 Hz:
d 20.....d 160 3.2 kW
d 160....d 450 4 kW mechanically regulated
5 kW electronically regulated
Start the generator first, then connect the welding unit.
The idle voltage should be set to approx. 240 volts. When
turning the generator off, disconnect the welding unit first.
Important
The working output power of the generator de-
creases by about 10% per 1,000 m of altitude.
During the welding process no other device con-
nected to the same generator should be operated.

4 Principles of Operation
The HST 300 Manual USB 2.0 allows welding electrofusion
fittings that require of welding voltage from 8 V to 48 V.
Every fitting has its own, specific welding voltage and
welding time. For a proper welding operation, these data
have to be entered manually.
The microprocessor-controlled HST 300 Manual USB 2.0
Welding Unit controls and monitors the welding process in
a fully automated fashion. While doing so, the sensor on
the welding cable cycles to measure to ambient tempera-
ture and to adjust the welding time based on it.

Caution
CAUTION in case of System Errors!
If during the auto-test that the unit performs at
start-up, an error is detected, a “System Error” mes-
sage shows on the display. When this happens, the
welding unit has to be disconnected immediately
from the power suppy and the fitting, and it has
to be shipped to the manufacturer for repair.
Important
The dust cap for the interface has to cover the port
during operation, in order to keep humidity and
contaminations away.
5.2 Connecting the Fitting
Connect the connection terminals to the fitting and check
for proper contact. Use terminal adapters if needed. The
contact surfaces of the cable connection terminals or adapt-
ers and the fitting have to be clean. Dirty terminals may
lead to improper welding and also to overheated and fused
connection terminals. Protect the cable connectors against
getting dirty at all times. Terminals and push-on adapters
should be considered consumables and, therefore, have to
be checked before every welding operation and replaced
if damaged or dirty.

6 Downloading the Reports
Interface
USB A Interface Port
for connecting USB mass storage media (such as a
memory stick)
The interface port complies with the USB version 2.0
specification (i.e., maximum data rate of 480 megabits
per second).
Important
Before transferring data, it is highly recommended
to switch the welding unit off and on again. If this
fails to happens, there is a risk of data transfer
failure, or reports in the welding unit may be cor-
rupted.
Important
When transferring welding reports to a USB stick,
always be sure to wait until the display shows the
“Download finished” message before you discon-
nect the USB stick from the product. If you discon-
nect it too early, the unit may ask you whether you
want to delete the reports in memory, although
they were not properly transferred. In this case,
if you delete the contents of the report memory,
the welding reports would be irrevocably lost and
would not be available elsewhere either.
6.1 Selecting the File Format
Connecting the storage media causes the the screen to
appear in which the format of the output file with the
welding reports can be selected: a PDF file with an ab-
stracted or extended version of the report, the format of
the welding data management application DataWork or
a CSV file. Using the ñand òarrow keys, select the file
type you need and confirm your selection by pressing the
START/SET key.
The CSV format enables import of the report data into
a database or spreadsheet application, provided this ap-
plication can read the format; this is the case, e.g., with
Microsoft Excel.
The Service Report option is not important for normal
operation. In the scope of computer-assisted unit service,
this report lists the events related to the maintenance of
the welding unit.

After the file type was selected, the next screen offers a
“By Commission Number,” a “By Date Range,” and a “By
Report Range” options. Depending on the selection, the ñ
and òarrow keys can be used to select from the commis-
sions currently in system memory the desired one, of which
the reports should be downloaded, or the alphanumeric
keypad can be used (see Info in Sect. 5.2) to enter a start
date and an end date, or the first and the last report, that
define a range of dates or a range of reports of which the
reports should be downloaded. When you press the START/
SET key, you cause the selected reports to be transferred
to the storage media.
6.4 Understanding the Report Download Process
The download starts automatically after a selection was
made among the options. Wait for all the selected reports
to transfer and the “Download completed” message to
appear on the screen.
If a problem occurs while the download is in progress, a
“Not ready” message shows. After the problem condition
is cleared, the download resumes automatically.
Info
If the welding unit recognizes a problem that
cannot be cleared while the data transfer is in
progress, it does not resume the process and dis-
plays a “Download cancelled” error message. To
acknowledge this error, press the START/SET key.
6.5 Deleting Data from Memory
The report data in memory can be deleted only after all
welding reports were transferred, which is indicated by the
“Download completed” message. When the storage media
is unplugged, a “Delete Memory” message appears. If the
START/SET key is pressed at this point, a further confirma-
tion message “Delete Memory, sure?” is shown, which has
to be confirmed by pressing the START/SET key once again.
Then, the report data in memory are deleted.

and the number of currently available, unused reports. To
quit this screen, press the STOP/RESET key.
If the scheduled service is overdue, a service due message
appears on the screen as soon as the unit is plugged into
the mains or generator power supply. This message has to
be acknowledged by pressing START/SET.
7.2 Measuring Resistance
When the START/SET key was pressed to initiate a welding
process, the resistance value of the fitting is measured. If
the value is obviously incorrect, the welding unit aborts
welding and displays a “Resistance Error” message. It also
displays the actual resistance value measured for the con-
nected fitting.
The reason for a resistance error may be poorly contacting
and/or worn connection terminals. Therefore, if this error
occurs, check them for proper fit and, if worn, replace
them with new ones.
7.3 Overheating Switch
The welding process aborts if the temperature of the trans-
former of the welding unit is too high. The overheating
circuit breaker for the welder stops the welding process
if the temperature reading is too high and the remaining
welding time is longer than 800 seconds. The display and
the welding report will show an “Overheated” message.
