1. High Temperature Resistance: The surface of the pressure wheel can withstand high temperatures up to 260C. It is made of high-temperature-resistant silicone material, finely processed. The matte frosted surface is wear-resistant, smooth, and highly resilient. Suitable for high-temperature welding of PVC waterproofing membranes and tarpaulin membranes. 2. With A Test Probe: The seam roller can effectively detect the welding joint of TPO coil material, inspecting all welding seams to ensure there is no missing welding, ensuring the reliability of welding seam quality. 3. Convenient Operation: Featuring a 1 wheel 2 bearing design, the seam roller with probe is stable and does not deviate, making operation more flexible and preventing jamming during the construction process. This effectively improves welding speed and construction quality. The high-speed steel bearing design offers greater stability, with a sturdy and detachable structure for easy replacement and more convenient operation. 4. Handle Design: The handle is made of premium wood, wear-resistant and ergonomically designed. It is durable, provides a comfortable grip, and fits naturally in the hand. 5. Wide Application: Mainly used for welding membrane and sheet materials and inspecting and missed welding of waterproof layer welds, such as PVC, TPO coil welding joints, EPDM adhesive joints, and more.
