6. Commissioning your HEMTEK ST / K-ST

6.1 Work environment and safety

The hot air welder should be used only in well-ventilated indoor areas.
Never use the hot air welder in explosive or readily inflammable surroundings and maintain sufficient
distance from combustible materials or explosive gases at all times.
Read the material safety data sheet of the manufacturer of the material and follow that company's
instructions. Be careful not to burn the material during the welding process.
Use only stable tables or workbenches that can support the load without tipping over.
Contact the manufacturer without fail should uncertainties arise during installation or operation.

Power supply cord and extension cable
The nominal voltage specified on the device (see technical data) must match the mains voltage.
Power plants for energy supply
When using power plants as an energy supply, please ensure that the power plants are grounded and equipped
with earth leakage circuit breakers.
For the nominal output of the power plants, the formula 2 x nominal output of the hot air welder applies.
Please note that the automatic welder is only intended to be used indoors. Ensure that all requirements from the
instruction manual for the unit are met.

6.2 Operating readiness

Check the setting guide (14) and afterwards the basic setting of the welding nozzle (18).
Check the table fastening (7) is fastened correctly and that the work table is stable.

6.3 Positioning

• Check whether the material to be welded is clean on the upper and lower sides.
• Afterwards, check whether the welding nozzle (18) and the drive/pressure roller (15/16) are clean.
• Now feed the material neatly into the guide (14) and fold the contact pressure roller (16) downwards with the
help of the weight grip (17).
• Check whether the material is positioned parallel to the welder and whether the welding nozzle (18) is easily
retracted.
During work interruptions or when cooling
down, you must swivel the hot-air blowers
(1) into park position using the pedal or
pressure buttons (21).
