Extension Cables; Starting The Device; Welding Process - Leister WELDPLAST S1 Notice D'utilisation

Extension cables

• Ensure the minimum cross-section when using extension
cables:
• The extension cable must be approved for the site of use (e.g.
in the open air) and marked correspondingly.
• When using a power unit for power supply, its nominal power
rating is: 2 × nominal power rating of the extrusion welder.

Starting the device

• Install the relevant welding shoe (8), pre-heating nozzle (9), and hot air duct (16) if necessary (Changing
accessories, page 37).
• Switch the extruder on at the main switch (1). Depending on the pre-heating air temperature, either the startup
display or «Cool down mode» will appear on the display (5). Press the «Heating on/off» key (23)
the heating process.
• If the device is ready for operation, the LED light (31) will switch on automatically (factory setting).
• Press the on/off switch for drive (2) to start the drive.

Welding process

• Insert the filler rod (ø 3 or 4 mm) into the filler rod insertion point (11).
• The filler rod is automatically drawn through the filler rod insertion point (11).
There must be no resistance when the rod is inserted.
CAUTION!
Always operate the device with the filler rod, but never feed the filler rod into both filler rod
insertion points at the same time.
• The speed at which the filler rod is drawn in can be set using the potentiometer (3).
• Pause the delivery of material using the on/off switch for drive (2).
• Direct the pre-heating nozzle (9) onto the area to be welded.
• Pre-heat the area to be welded with oscillating movements.
• Place the device on the prepared welding area and press the on/off switch for drive (2) again.
• Carry out a test weld according to the welding instructions from the material manufacturer and the national
standards or directives. Check the test weld.
• Adjust the temperature setting, output volume, and air volume as necessary (see "Setting the welding parame-
ters" chapter, page 31).
• During a longer period of welding, the on/off switch for drive (2) can be kept in continuous operation using
the drive locking device (4).
CAUTION!
• PVC-U and PVC-C are processed in the menu of PVC-U.
• To prevent corrosion when processing PVC-U, PVC-C, ECTFE, PVDF etc., we recommend flushing the extrusion
welder with HD-PE when you have finished welding.
