Geomembrane Welding Machine PFE800D

• Digital display hot wedge welder.

• This machine can not only display the welding temperature and welding speed, but the control system adopts closed-loop control, regardless of the external voltage change, or the welding direction up or down under the change of the external environment, such as negative feedback automatically adjusts the set temperature and speed, so that The welding parameters are more stable and the welding quality is more reliable.

• The welding machine adopts a cash hot wedge structure, which is small in size and light in weight. Suitable for welding of all hot melt materials such as HDPE, LDPE, PVC, EVA, ECB, PP, etc. The products are used in tunnels, subways, water conservancy, agriculture, landfills, waterproof and seepage engineering, chemical mines, sewage treatment, roof construction, etc field.

• Accept small orders.

• Satisfy small batch customization services.

• The fault code is displayed.

• Meet the voltage requirements of 120V and 230V in different countries and the plug requirements of EU standards, American standards, and British standards.

• 800W is the standard power, which is especially suitable for welding materials with a thickness of less than 0.8mm.

• 1100W is an enhanced power, especially suitable for welding materials with a thickness greater than 0.8mm. In the case of the same welding quality, the speed is faster and the efficiency is higher.

• The product comes with an additional repair spare parts kit, including repair tools, fuses, spare hot wedge and pressure rollers.
