Overview
Welding tarps, truck curtains and tent covers is the job here: the TRIAC ST hand tool blows heated air through a slot nozzle to soften PVC layers, and the silicone roller presses the overlap together. Swap between the wide and narrow slot nozzles to match the seam.
Everything needed for field repairs on PVC tarps and industrial fabrics arrives together, so there is no hunting for the right nozzle or roller. Being the non-digital version, heat is set by dial rather than read from a display, and the listing gives no wattage or temperature range to plan around.
Who it's for
Billboard installers, marquee crews and boat cover makers who patch or join PVC fabric will use every piece in the case. Shops welding metal or rigid plastic pipe should look for a tool documented for that work.
Pros and cons
- Nozzles and roller come in one kit
- Tool case included for site work
- Two slot nozzle widths for different seams
- Stainless steel push fit narrow nozzle
- Wattage and temperature range not listed
- Analog control, no digital temperature display
- Built for 120v outlets
- Listing gives two different tool part numbers
Performance notes
Weld strength depends on matching air temperature and speed to the fabric, then pressing the overlap with the roller while the coating is still soft. The slot nozzle spreads heat across the seam width, so the wider nozzle covers broad overlaps in one pass and the narrow one suits tight repairs. Without a digital readout, settings are found by trial welds on scrap.

Frequently asked questions
Can the Leister TRIAC ST kit weld billboard vinyl and boat covers?
Yes. The listing names billboards, tents, covers, marquees, tarps, lorry side curtains and boat and caravan covers as uses, all PVC or industrial fabric work.
Does the Leister TRIAC ST in this kit have a digital temperature display?
No. The kit uses the non-digital version of the TRIAC ST, so heat and speed are set without a digital readout.
Is the Leister TRIAC ST kit for welding metal or rigid plastic pipe?
The listing only describes welding PVC, tarps and industrial fabrics. It does not mention metal or rigid pipe, so do not count on it for that work.
How does the pressure roller help a tarp weld?
The 40mm silicone roller applies constant pressure to the heated overlap, which bonds the two PVC layers along the seam.
