• The power voltage must correspond with the value given on the nameplate. Extension cords must have a
conductor cross section of minimum 3 x 1.5 mm2 with capacity not less than 10A. Confi rm that external lines
have been well connected, check that the power switch is in the OFF position. Turn all temperature and speed
controls to the 0 position, open
tension lever (6) to disengage pressure roller, then insert the plug.
• Turn on the power and select temperature and speed, take 2 narrow pieces of material for welding trials.
Temperature selection can be diff erent for the same material at diff erent ambient temperature and material
thickness. To determine the best welding result, adjust the speed to approximately 2 m/min, and then make
diff erent trial welds while slowly adjusting the temperature from low to high. (approximately 300 – 380 °C).
• 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 (welded bead/weld path). If required, correct the speed with
potentiometer drive (12).
• When welding is completed, disengage tension lever to prevent damage to the pressure rollers. Pressure rollers
should never run against each other without material between them.
• Push On/Off -button for heating and drive.
• Allow device to cool-down.
• Disconnect the mains voltage plug.
Perform a test welding according to the welding instructions of the material manufacturer and the
national standards or guidelines. Check the test welding.
