WM 740 Four Head Welding Machine

Standard Features

  • Welds four corners of PVC profiles simultaneously at 90 °with high sensitivity and strength
  • Beckhoff brand, high performance industrial PC operated by Windows XP Embedded. Fanless motherboard system works between 0°C – 55°C, and it comes with a 15” touch screen display
  • Data transfer via ethernet network connection, wireless network connection or USB interface
  • Welding parameters are defined by the user for every individual profile(up to 10,000 profiles)
  • Welding temperature, melting and welding times can be adjusted individually for each profile type.
  • All machine axes are moved by hardened steel ball screw which provides accuracy and durability.
  • PC controlled (PID) heat control system to obtain strong welding results in compliance with standards.
  • Summer / winter working mode is automatically selected,so the temperature adjustment is done easily
  • Horizontally placed strong mechanical heating plates distribute heat homogeneously without being affected from difficult working conditions.
  • Easy and fast change for teflons by specially designed roll up teflon system.
  • Easy and fast change for welding moulds
  • Works effectively by compressed air supplied to the system
  • White or colour profiles can be weld with the same sensitivity
  • Central lubrication system minimizes maintenance time
  • Reports can be created for daily, weekly, monthly and annual production
  • Light barriers and safety equipment confors to CE machine design with full security
  • Stable and accurate data transfer between this machine and the CNC corner cleaning machine via Industrial quality Ethernet connection
