Uniroof 700: The Ultimate Automatic Welding Machine for Thermoplastic Membranes
Experience precision and reliability with the Leister Uniroof 700, an advanced automatic welding machine designed for thermoplastic membranes on flat and slightly inclined roofs. Whether you’re working on a small-scale project in Riyadh or tackling large roofing installations in Jeddah, this machine delivers unmatched quality and efficiency.
Why Choose the Uniroof 700?
In the competitive construction industry of Saudi Arabia, achieving consistent welding quality is crucial. With features like the Monitored-Welding-Assistant, Leister Quality System (LQS), and power management for constant performance, the Uniroof 700 ensures every weld meets the highest standards. Let’s dive into its standout features:
- Monitored-Welding-Assistant: This feature provides real-time monitoring during the welding process. If the machine leaves the welding area or undervoltage occurs, an alarm alerts the user, and the digital display turns red. This ensures greater control and prevents costly errors on-site.
- Leister Quality System (LQS): Document your welding quality effortlessly. The LQS monitors critical parameters like temperature, air volume, and speed, ensuring precise documentation. Reports can be generated as PDF or CSV files via the myLeister app, complete with GPS coordinates to verify work quality—an invaluable tool for contractors in Saudi Arabia seeking transparency and accountability.
- Standard Nozzle for Homogeneous Weld Seams: The included standard nozzle guarantees uniform weld seams, making it ideal for TPO, PVC, EVA, PIB, and modified bitumen membranes. Its design allows for easy insertion into overlap seams, saving time and effort while maintaining professional results.
- Power Management System: Say goodbye to inconsistent performance due to undervoltage. The Uniroof 700’s power management system maintains constant welding performance even under challenging conditions. If excessive undervoltage occurs, the machine shuts off automatically to protect weld quality—a key benefit for projects in remote areas where power supply may fluctuate.
- Welding Recipes in the myLeister App: Customize and save welding recipes tailored to specific materials and conditions. Access these settings directly from your smartphone or tablet through LiveView functionality, enabling jobsite managers in Riyadh and Jeddah to oversee operations remotely.
- Eco Mode for Energy Efficiency: Save up to 30% energy when operating at maximum capacities. Eco-mode reduces operational costs without compromising performance, making it an environmentally friendly choice for construction professionals in Saudi Arabia.
- Low-Maintenance Brushless Motors: Designed for durability, the brushless motors minimize maintenance needs, ensuring long-term reliability and reducing downtime on critical projects.
- Compact Design with Edge Welding Capability: The slim profile and movable transport axis allow seamless transitions between applications, eliminating the need for time-consuming retooling. It also excels at edge welding, reaching areas as close as 100 mm to parapets and skylights.
- Superior Speed and Performance: Capable of welding PVC membranes at speeds up to 10.8 ft/min at 1076°F, the Uniroof 700 is 20% faster than its predecessor, the UNIROOF 300. This boost in productivity makes it perfect for high-demand projects across Saudi Arabia.
- Voltage Display for Enhanced Safety: Check voltage levels before starting the welding process to avoid issues caused by defective extension cables. This proactive approach ensures consistent weld quality and protects against potential hazards.
Ideal Use Cases for the Uniroof 700
The Uniroof 700 shines in various scenarios, particularly for construction professionals in Saudi Arabia who demand precision and reliability. Here are some examples:
- Flat Roof Installations: Perfect for roofing projects covering up to 500 sqm, whether for residential buildings in Riyadh or commercial complexes in Jeddah.
- Slightly Inclined Roofs: Handle inclinations up to 30 slope grad with ease, ensuring smooth operation on both flat and gently sloped surfaces.
- Edge and Parapet Welding: Achieve flawless welds near edges, parapets, and hard-to-reach areas like skylight domes.
- Large-Scale Industrial Projects: From precast manufacturers to industrial clients, the Uniroof 700’s speed and efficiency make it a top choice for demanding applications.
