400 Butt Welding Machine – Central Body & Clamping System
The 400 Butt Welding Machine features a robust design with 4 main pulleys and induction-hardened chrome shafts. Its specially designed piston heads allow smooth operation even at low pressures (3–5 bar) ensuring uniform pulley movement. The machine’s pipe clamping plates, intermediate clamps, and injection-molded plates up to 560 mm in diameter make it significantly stronger and more reliable than other models on the market.
Heater Features
The butt welding machine heater is coated with special Teflon resistant up to 450°C. It includes a replaceable resistance element and consists of two parts, providing safe and efficient heating for plastic pipes during butt welding operations.
Trimmer Features
Equipped with injection-molded bodies and disks, the machine’s trimmer ensures smooth and precise pipe surfaces with a blade height of 0.25 mm. The chain tensioning mechanism allows easy adjustment during summer and winter, preventing potential chain breakage.
Hydraulic Unit & Control System
The 400 Butt Welding Machine is powered by an advanced hydraulic unit that manages all operations: heater electrical connection (via digital screen), trimmer control, on/off lever, pressure monitoring via manometer, and cylinder forward/backward movement. Hydraulic valves allow continuous adjustment of welding pressure, maintaining a consistent butt welding process. The unit is protected against dirt, easy to transport, and designed to accommodate additional fittings and components.
Applications
This machine is ideal for construction sites, workshops, and engineering systems such as water supply and gas pipeline installations. Compatible materials include PE, PP, and PVDF pipes and fittings.
