Features High Temperature Resistance The surface of the pressure wheel can withstand high temperature up to 260 C and is made of high temperature resistant silicone material, finely processed. Matte frosted surface, wear-resistant, smooth and more sturdy. Used for high-temperature welding PVC waterproofing membranes and tarpaulin membranes. With a test probe: the seam roller can effectively detect the welding joint of the TPO coil material, inspect all welding seams to ensure that there is no shortage of weld, and ensure the reliability of the quality of the welding seam. Convenient Operation: Adopting 1-wheel and 2-bearing design, the probe seam roller is stable and does not deviate, which makes the operation more flexible and avoids jamming during the construction process, effectively improving the welding speed and construction quality. The design of high-speed steel bearings is more stable, with a sturdy and detachable structure, making it easier to replace and operate more freely. Handle design: the handle is made of premium wood, wear-resistant and ergonomically designed. It is not easy to wear, has a comfortable feeling, and is closer to the hand. Wide Application It is mainly used for welding membrane and sheet materials and to verify virtual welding and lost welding of waterproof layer welds, such as PVC, TPO coil welding joints, EPDM adhesive joints, etc. 1.
