Leister TRIAC Drive


For pitched roofs, steep embankments and hard-to-reach areas, the Leister TRIAC Drive simplifies single-ply seam welding. When combined with the TRIAC S or TRIAC PID, you can create precise, consistent overlap welds of PVC-P, ECB, EPDM, CSPE and TPO membranes. 

Through hot-air and pressure, this semi-automatic overlap welder guides itself along a roofing seam and permanently joins thermoplastics and single-ply elastomers in the form of geomembranes, foils, water bars and coated fabrics.

  • Faster and more efficient than hand welding seams
  • Compact, lightweight and easy to maneuver
  • Adjustable heat and speed for flexibility on all types of materials and environmental conditions
  • Consistent pressure
