Putting into operation

Moving parts may not be touched. The danger exists of inadvertently becoming caught and
being pulled in.
• Insert the power plug, turn on the power by pressing the On/Off buttons for heating and drive (14 + 17) and
select temperature and speed, then take two narrow pieces of material for welding trials. Temperature selection
can be different for the same material at different ambient temperature and material thickness. To determine
the best welding result, adjust the speed to approximately 2 m/min, and then make different trial welds while
slowly adjusting the temperature from low to high.
• Evaluate welding parameters by carrying out tensile testing.
• After temperature and speed have been determined, insert material to be welded between the two pressure
rollers, and engage the tension lever to start the welding process.
• Check the welded seam. If required, correct the speed with the potentiometer drive (12).
• When welding is completed, disengage the tension lever to prevent damage to the pressure rollers. Pressure
rollers should never run against each other without material between them.

Switching off

• Push On/Off-button for heating and drive.
• Disconnect the mains voltage plug.
• Allow device to cool-down.
Test weld
Perform a test welding according to the welding instructions of the material manufacturer and the
national standards or guidelines. Check the test welding.
