From October 8–15, 2025, Leister will be the go-to destination in Hall 11, Booth E16 for anyone who welds, heats, or forms plastic. Already during the first days of the show, the crowds are strong–and so is the curiosity. No surprise there: Leister is presenting not only exciting live demonstrations but also several product premieres that are drawing attention across the industry. And the brand-new booth design–spanning an impressive 124 m²–makes a bold statement. 

Welding Station Draws the Crowd 

“The crowd is especially strong at the welding station, where the extruders and the NEXHEAT are demonstrated live. That draws a lot of interest and attention from trade show visitors. Customers are also impressed by our booth–especially the large screen and the new NEXHEAT,” says Roland von Ah, Head of Sales Partner Program at Leister International AG.

Welding with Battery Power 

A clear highlight is the new NEXHEAT 300 A-LP, a cordless handheld welder that combines maximum mobility with precise performance. Whether for roofing, flooring, textiles, or civil engineering, it offers temperature control from 50 to 500 °C, a digital display, and an integrated LED light. The result: ultimate freedom on the job site without compromising weld quality. A true milestone for anyone who wants to work independently and powerfully-without limits. 

“Finally, there’s a cordless welder that keeps a stable temperature all the way until the battery runs out. The flexibility on construction sites-without having to look for a place to plug in–is fantastic,” remarks a customer at the Leister booth. 

New Air Heaters for Machine Builders

The new LHS 210 P and LHS 410 P compressed air heaters set new standards for hot-air processes up to 6 bar. Compact, powerful, and fanless, they are ideal for tight installation spaces in industries such as food processing, packaging, automotive, and medical technology.

Perfect Pool Seams in Record Time

Summer will be here before you know it! Leister is also showcasing its new pool welding machine, the UNIDRIVE 505, which revolutionizes butt welding for pool membranes. It’s fast, clean, and almost invisible–no sealing required. Perfect for swimming pool designs that demand flawless aesthetics. 

Next-Generation UNIPLAN 

The new generation of the proven UNIPLAN 510 and UNIPLAN 310 impresses with efficiency, ergonomics, and power. Ideal for welding banners, tarpaulins, and tents–on the table or on the floor. 

Experience the Brand Values Live 

At the booth, Leister’s brand values PIONEER – PERFORMANCE – PREMIUM come to life in impressive ways. 

  • PIONEER stands for innovation with responsibility: the newly developed ECO Drive motor with ferrite magnet is highly energy-efficient, resource-friendly, and easy to repair–a real step forward in sustainability. 
  • PERFORMANCE shines through the new NEXHEAT 300 A-LP, which delivers full power for cordless welding and sets new standards on construction sites. 
  • PREMIUM at Leister means not only top product quality but also a global service network that guarantees customer proximity and support at the highest level–wherever Leister tools are used around the world. 

When Coffee Meets Hot Air 

And here’s a special highlight: A coffee roaster is on display right at the booth, with its interior revealing the Leister MISTRAL 6 SYSTEM. It ensures that coffee beans are roasted evenly and gently–with precise temperature control, energy efficiency, and reliability. And for anyone who now craves coffee: a barista is on site, treating visitors to freshly brewed espresso and more.
