Thanks to the Geostar G7’s innovative wedge connection system, replacing the hot wedge takes under a minute. This quick-change capability minimizes interruptions, allowing you to focus on getting the job done efficiently.
- Integrated Display for Real-Time Monitoring: Stay in control with the built-in display that shows critical welding parameters and voltage levels. This feature ensures optimal settings are maintained throughout the welding process, providing peace of mind and consistent results every time.
- Strong Drive Motor for Reliable Performance: The powerful drive motor guarantees smooth and steady movement during welding operations. Capable of achieving speeds up to 12 m/min (39 ft/min), the Geostar G7 covers large areas quickly, making it ideal for expansive geomembrane installations across Saudi Arabia.
- Sophisticated Frame Made of Solid Cast Aluminium: Durability meets precision with the Geostar G7’s solid cast aluminium frame. This robust construction ensures long-lasting performance, even in demanding environments like Riyadh’s harsh climate or the rugged terrains of Jeddah’s mining sites.
- Single-Hand Operation with Integrated Clamping and Handle Locking Mechanism: Simplify your workflow with the Geostar G7’s ergonomic design. Its integrated clamping and handle locking mechanism allows for effortless single-hand operation, freeing up your other hand to manage materials or tools simultaneously.
