Weldy Energy HT1600 Overlap Welding Kit

The Weldy Energy HT1600 Overlap Welding Kit is a five-piece complete manual overlap welding kit comprising the HT1600 1600 W heat gun with stepless 40 to 700 degree C temperature control, ceramic heating element, and outdoor use rating – paired with a 40 mm wide-slot nozzle, 20 mm wide-slot nozzle, 40 mm silicone pressure roller, and spare carbon brushes, supplied in a durable storage case – designed for manual overlap welding of PVC, TPO, and thermoplastic roofing membranes, technical textiles, and construction sheeting for professional, commercial, and DIY overlap welding applications.

Complete Manual Overlap Welding for PVC and TPO Roofing Membranes and Technical Textiles

Manual overlap welding of thermoplastic roofing membranes and technical textiles – PVC flat roofing membranes, TPO waterproofing sheets, PVC tarpaulins, and coated technical textile seams – requires the heat gun to deliver controlled hot air through a nozzle that fits precisely into the overlap seam to pre-heat both membrane faces simultaneously, followed by immediate pressure roller consolidation of the seam while the material is at fusion temperature. This three-element process – controlled heat delivery, correct nozzle width for the seam, and immediate consolidation pressure – determines the quality, watertightness, and durability of the completed overlap seam.

The HT1600 Overlap Welding Kit assembles these three elements as a matched, pre-configured set. The 40 mm and 20 mm wide-slot nozzles cover the standard overlap seam widths of PVC and TPO roofing membrane overlap joints and the narrower overlap seam widths of technical textile, tarpaulin, and detail membrane work – with the correct nozzle selected for the specific seam width of each application without requiring separate nozzle sourcing. The 40 mm silicone pressure roller consolidates the heated seam immediately behind the nozzle pass, applying the consistent pressure that adhesion across the full seam width requires before the material cools below fusion temperature. And the HT1600’s stepless temperature control to 700 degrees C, ceramic element consistency, and outdoor use rating ensure that the heat gun component of the system delivers the correct, consistent temperature to the membrane overlap throughout the welding session. For roofing contractors, waterproofing installation teams, and technical textile fabricators across Oman and the GCC who require a complete, ready-to-use manual overlap welding solution for PVC and TPO membrane work, the HT1600 Overlap Welding Kit provides the correctly specified, pre-assembled kit from a Leister Group brand at an accessible price point.

HT1600 Overlap Welding Kit Contents and Application Features

• HT1600 Heat Gun – 1600 W with Stepless 40 to 700 °C Temperature Control: The HT1600 heat gun provides the hot air source for the overlap welding system – with stepless temperature dial control from 40 to 700 degrees C, ceramic heating element for consistent thermal output, 240 l/min airflow at 2600 Pa static pressure, cool-down function for element protection, outdoor use rating, and dust-protected durable housing. The outdoor use certification is directly relevant to roofing membrane overlap welding, which takes place on exposed rooftop surfaces in the ambient conditions of outdoor construction sites across Oman and the GCC.
• 40 mm Wide-Slot Nozzle for Standard Membrane Overlap Seam Welding: The 40 mm wide-slot nozzle fits into the standard overlap seam of PVC and TPO roofing membrane installations – inserting between the upper and lower membrane surfaces at the seam edge and directing hot air simultaneously to both membrane faces across the 40 mm nozzle width to pre-heat both surfaces to the fusion temperature required for adhesion across the full seam width. The 40 mm width corresponds to the standard overlap seam width that PVC and TPO roofing membrane installation specifications commonly require for compliant seam strength.
• 20 mm Wide-Slot Nozzle for Narrower Seams and Detail Overlap Welding: The 20 mm wide-slot nozzle provides the narrower hot air delivery width for overlap seam applications where a 40 mm seam width is not appropriate – including narrower specification seams on technical textiles, tarpaulin and banner overlap joints, detail seam sections at membrane corners and penetrations, and repair seam applications where the available overlap width is less than 40 mm. The two-nozzle provision in the kit covers both standard and narrow overlap welding requirements without requiring separate nozzle procurement for each seam width encountered in the application scope.
• 40 mm Silicone Pressure Roller for Seam Consolidation: The 40 mm silicone pressure roller applies consolidation pressure to the heated seam immediately behind the nozzle pass – pressing the pre-heated membrane surfaces together under controlled, consistent force while both faces are at fusion temperature. The silicone roller material resists the heat transferred from the freshly welded seam, maintains its compressive geometry under the thermal conditions of active overlap welding operation, and produces a clean seam surface without adhesion to the membrane face that harder roller materials would cause on soft thermoplastic membrane surfaces.
• Spare Carbon Brushes for Uninterrupted Service: Spare carbon brushes for the HT1600 brush motor are included in the kit – providing the replacement brushes required when the motor brushes reach their service end-of-life, enabling the brush replacement to be performed from the kit’s own contents without requiring separate spare parts procurement. This inclusion ensures that the HT1600 motor can be maintained at correct brush contact throughout the service life of the unit without an unplanned parts sourcing delay interrupting the overlap welding programme.
• Durable Storage Case for Kit Protection and Organisation: The complete five-piece kit is supplied in a durable storage case that protects the heat gun, nozzles, pressure roller, and spare brushes from dust, debris, and mechanical damage during site transport and storage – maintaining all components in clean, ready-to-use condition between overlap welding sessions and providing organised storage that prevents individual components from being misplaced across the active construction and installation sites where the kit is deployed.
• Suitable for Professionals and Beginners in Construction and Commercial Applications: The HT1600 Overlap Welding Kit’s simple stepless temperature dial operation, pre-selected matched nozzle widths, and included pressure roller eliminate the accessory selection knowledge and parameter configuration experience that assembling a manual overlap welding system from individual components requires – making the kit appropriate for operators at all experience levels, from established roofing and waterproofing professionals to operators undertaking overlap welding work for the first time on construction and commercial projects.

Overlap Welding Applications for the Weldy HT1600 Kit in Oman and the GCC

• PVC Flat Roofing Membrane Manual Overlap Seam Welding: Performs manual hot air overlap welding on PVC thermoplastic roofing membranes at perimeter details, corner sections, penetration surrounds, and confined areas where automatic welding machines cannot operate – with the 40 mm nozzle covering standard PVC roofing membrane overlap seam widths and the silicone pressure roller consolidating the seam immediately after nozzle heating on flat and low-pitched roof surfaces across residential, commercial, and industrial buildings in Oman and the GCC.
• TPO Membrane Overlap Welding for Waterproofing Applications: Welds overlap seams on TPO thermoplastic roofing and waterproofing membranes at detail locations and repair sections – where the HT1600’s temperature range to 700 degrees C accommodates the higher welding temperature that TPO membrane fusion requires compared to PVC, and where the outdoor use rating supports deployment on the rooftop and exposed surface environments that TPO waterproofing installation presents.
• Technical Textile and Tarpaulin Overlap Seam Repair and Fabrication: Using the 20 mm nozzle for narrower seam widths and the 40 mm nozzle for standard tarpaulin overlap dimensions, the kit performs manual overlap seam welding on coated PVC technical textiles, tarpaulins, covers, and banner materials – providing the repair and fabrication capability that on-site tarpaulin damage repair, cover panel fabrication, and technical textile seam joining requires without access to a fixed production welding machine.
• Roofing Membrane Detail and Repair Welding on Construction Sites: Provides the complete manual overlap welding capability for on-site roofing membrane repair sections, overlap seam remediation, and detail area welding on flat roofing projects across Oman and the GCC – where the kit’s outdoor use rating, durable storage case, and complete accessory provision enable immediate deployment on active rooftop sites without additional equipment procurement.
• Construction and Commercial DIY Thermoplastic Overlap Welding: The pre-assembled kit format, simple HT1600 operation, and complete nozzle and accessory provision make the HT1600 Overlap Welding Kit accessible for construction operators, facilities maintenance teams, and skilled DIY practitioners who require a capable overlap welding solution for PVC and TPO membrane seam work without the specialist equipment knowledge that assembling individual welding components requires.
