The DIODE S and DIODE PID are both designed for use in hand-held production processes. They are lighter in weight than the TRIAC.
When choosing the Leister Diode, there are two options for high-quality work: the closed-loop DIODE PID provides the perfect welding temperature at all times, the DIODE S easily puts you in control with a manual temperature knob.
- Operated with MINOR or ROBUST blower or compressed air
- Digitally controlled and displayed temperatures (DIODE PID)
- Cooled heating element tube
- Suitable for field applications when used in combination with a MINOR blower
- MINOR blower and DIODE PID with screw-on drawing nozzle

172.483 | Seam Weld Tester - multitool
The Leister Seam Weld Tester Multitool is designed for non-destructive testing of overlap welds on thermoplastic roofing membranes such as PVC and TPO. Developed in collaboration with Victorinox, this multifunctional tool combines a precision test probe with practical features including a Phillips screwdriver, bottle opener, fastening ring, and large serrated knife blade.
The redesigned Leister test probe glides smoothly and ergonomically along weld seams without damaging the membrane. If the probe slips into the overlap, a leak has been found and can be repaired. Suitable for both right- and left-handed users, it features an integrated hole that allows for easy one-handed opening—making it an essential companion for efficient, on-site weld inspection.
