If you are seeking optimal equipment for TPO, PVC membrane installation in your TPO, PVC membrane waterproofing projects, from pitched to flat roofs, the Weldy brand (Switzerland/Leister Group) offers two prominent TPO membrane welding machines: the miniwelder roof2 and the roof40. This article will help you understand their functions, differences, and the right choice for each application.
The Weldy miniwelder roof2 is the ideal solution for projects that demand high flexibility and mobility.
Ultra-Lightweight (4 kg): At only 4 kg (8.8 lbs), the machine is extremely light and easy to operate, making it perfect for TPO, PVC membrane welding on pitched roofs without causing operator fatigue.
Superior Speed: Boosts efficiency up to five times faster than traditional manual welding methods, providing significant time savings in the TPO, PVC membrane installation process.
Application Range: Specifically designed for thin membranes, suitable for all PVC and TPO membranes with thicknesses between 0.3–1 mm.
Hot-Wedge Welding Technology: Uses a hot-wedge (chrome steel, aluminum, or copper) to ensure safe contact welding and high quality, completely eliminating the need for expensive, toxic solvent-welding agents.
Specifications: 230V/800W power, continuously adjustable welding temperature between 60°C and 480°C.
The miniwelder roof2 is the perfect choice for individual installers or small projects, focusing on TPO, PVC membrane waterproofing on pitched roofs where lightweight, fast-handling equipment is required.
The Weldy roof40 is an automatic TPO membrane welding machine designed to handle a wide range of requirements in construction and industry.
Universal Welder: Virtually unlimited applications, from TPO, PVC membrane installation on flat and pitched roofs, pool waterproofing, to overlap welding of technical textiles or industrial fabrics (tarpaulins, banners).
High Performance: Powerful 230V/3450W ensures stable heat and fast welding speed (up to 10 m/min).
Automatic and Digital Design:
Welding parameters (speed, temperature, air flow) are intuitively adjusted via the digital display.
Closed-loop technology ensures precise control over temperature and speed.
Brushless Drive: Guarantees durable, low-maintenance, and reliable operation.
Accurate Close-to-Edge Welding: Capable of welding close to edges, down to 100 mm (e.g., in narrow parapet areas), offering great flexibility in tight spaces.
Optimal Design: Weighs 16 kg, includes a guide rod, and features an ergonomically balanced design that allows the machine to easily handle inclines up to 30 degrees.
The roof40 is the workhorse for large contractors, requiring high speed and reliability for large-scale or diverse TPO, PVC membrane waterproofing projects.
Choose the miniwelder roof2 if:
You frequently work on pitched roofs or need to weld small, confined details.
Your TPO, PVC membrane waterproofing project involves membranes with a thickness under 1 mm.
You require a light, easily transportable TPO, PVC membrane welding device.
Your budget for a fully automatic machine is limited.
Choose the roof40 if:
You are a large contractor who needs high speed and productivity for flat roofs.
You require a versatile TPO membrane welding machine capable of working with PVC, TPO, and other industrial materials (banners, tarpaulins).
You prioritize automatic technology, precise digital control, and high durability (brushless motor) for large-scale projects.
With these two options from Weldy, achieving high-quality TPO, PVC membrane welding for effective TPO, PVC membrane waterproofing has never been easier. Whether it's the flexibility of the miniwelder roof2 or the comprehensive power of the roof40, Weldy has the optimal solution for your TPO, PVC membrane installation needs.
