The compact design of the EXWELD sigma series and the low device weight represent an absolute novelty in this performance category. The EXWELD sigma is available with self-contained (sigma SC) and external power supply (sigma EC). An easy to maintain machine concept allows for easy and fast exchange of the extrudate heating elements.
Suitable for welding of PE, PP, PVDF, PVC (optional) and other weldable thermoplastic material. By default equipped with a twistable welding shoe (Twisty).
User friendly and practice oriented design including:
Electronic control of the extrudate heating
SC version with self-contained air supply by a WEGENER-Airtherm 2.200 W with individual control of the air temperature
EC version with external air supply by a WEGENER-pre heater with 2.500 W and integrated control of the air temperature
Cold starting prevention (the device is only ready for use after having reached a determined temperature)
Monitoring of the set-point-temperature of the extrudate heating including motor stop function in case of too high divergence
Easy to exchange PTFE welding shoes, adjustable front handle
Self adjusting welding shoe with integrated air duct
