Butt welding machine SWT-V800/500A

automaticfor pipesfor plastic pipe

Automatic CNC hydraulic butt fusion welding machines designed for high-precision joining of HDPE, PE, PP and PVDF pipelines in applications such as natural gas distribution, potable water, wastewater, mining and industrial fluid transfer. Units combine a fully enclosed CNC hydraulic controller with PLC touchscreen control, RFID access and thermal tooling for consistent, repeatable welds.

Key features

• Fully enclosed, compact CNC hydraulic controller unit for field durability.
• PLC touchscreen interface with RFID operator authentication and secure access control.
• Onboard storage and printing of welding reports (capacity > 2,000); USB interface for report export and printing.
• DuPont Teflon-coated heating plate for long life and stable temperature control (typical variation: ±2–3°C for compact models; ±5–6°C for larger systems).
• Lightweight aluminum clamps and compact mobile design for easier handling and transport.
• German-made oil seal kit ensuring stable hydraulic pressure performance and reliability.
• Four STUCCHI quick couplings (Italy) to simplify hydraulic connections and prevent oil leakage during assembly/disassembly.
• Integral shaft with top chromate treatment to reinforce chassis and resist twisting or deformation under heavy loads.
• Trimmer safety switch disables operation unless manually activated to enhance operator safety.
• Control system rated IP54 with servo-driven lightweight chassis; built-in rear sockets supply power to trimmer/heating plate, reducing dependency on external power units.
• Compliance with DVS/ISO/WIS welding standards; supports remote diagnostics and firmware upgrades.
