Frequently Asked Questions

Für welche Arbeiten ist der Thermoweld 40 geeignet?
Der Thermoweld 40 ist für präzise Überlappnähte auf PVC- und TPO-Flachdächern ausgelegt, was ihn besonders für professionelle Dachabdichtungen mit gleichmäßigen Schweißnähten geeignet macht.
Wofür ist die konstante Temperatur bis 620 °C im Alltag nützlich?
Die konstante Temperatur bis 620 °C hilft dabei, die Wärmezufuhr exakt zu steuern, sodass Nähte reproduzierbar und sauber gelingen — wichtig, wenn gleichbleibende Ergebnisse gefragt sind.
Ist der Schweißautomat auch für unterschiedliche Materialstärken geeignet?
Ja — die stufenlos regelbare Geschwindigkeit von 0,5 bis 14 m/min erleichtert es, das Gerät an Material und Arbeitsgeschwindigkeit anzupassen, was bei wechselnden Bedingungen mehr Kontrolle gibt.
Ist das Gerät für den Baustelleneinsatz ausgelegt?
Mit 42 kg Eigengewicht und Zusatzgewichten für mehr Anpressdruck ist der Automat auf stabilen, professionellen Einsatz ausgelegt — das unterstützt einen gleichmäßigen Schweißdruck auf dem Flachdach.
Ist der Thermoweld 40 eher für professionelle Anwender gedacht?
Ja — als 40-mm-Profi-Schweißautomat mit robuster Bauweise und Entwicklung in Schweden sowie Fertigung in der Schweiz richtet er sich klar an den professionellen Einsatz mit hohen Anforderungen an Präzision und Zuverlässigkeit.

Your welding expert for reliable PVC and TPO seams

With the SIEVERT Thermoweld 40 400V automatic welding machine, you get a genuine professional tool for welding roofing membranes cleanly, watertightly and durably – no guesswork, just maximum process reliability. Consistent seam quality is essential, especially on large flat roof areas: constant temperature, steady movement and controlled pressure. That’s exactly what the Thermoweld 40 is designed for.

The automatic welding machine has a 40 mm welding width and is ideal for PVC and TPO membranes. You can precisely adjust the temperature, airflow and speed to suit the material, substrate and weather conditions. This gives you repeatable results from the first membrane to the last. Compared with a hand torch or manual hot-air welding, you save time, reduce sources of error and significantly improve seam reliability.

Use in everyday roofing work

Position the Thermoweld automatic welding machine along the overlap, align it carefully with the seam and select the settings according to the membrane and outdoor temperature. The welding process then proceeds under control along the seam: hot air activates the surface, while the defined pressure reliably bonds the layers.

For details, connections or tight areas, pair the machine with hand tools as needed – for example, a suitable torch/hot-air tool, a pressure roller and a seam probe. This makes the Thermoweld a key part of modern roofing supplies and a true efficiency booster on the jobsite.
