Roofing

Automatic Welders

Uniroof AT

Leister recommends closed-loop technology for more welding reliability on the roof

Closed-loop provides more reliability in case of voltage drops on construction site
More reliability for the operator with display to set the right parameters

Closed-loop control of temperature, drive and air blower
Maintenance-free brushless motors on blower and drive
Display technology
230V/16A
17.5kg

Varimat V2

12 m/min maximum welding speed (depending on material).
Guide bar for ergonomic handling
Maintenance free blower means lower service costs.
User-friendly display with “e-Drive” (press and turn control) to recall preset and saved welding settings
Constant drive with regulated electronics

Using the new VARIMAT V2, polymer roofing membranes can be welded more rapidly resulting in lower cost. Users appreciate its streamlined ergonomics and its ease of use. The clearly laid out operating unit‘s „e-drive“ allows for the control of all relevant welding parameters.

Bitumat B2

Flameless welding of modified bitumen.
No shrinking of the insulation due to integrated air dam.
Uniform welding results
High working speed
Requires only one user to efficiently weld seams (torch weldingrequires two)

Welding of modified bitumen sheeting (SBS, APP) with the flameless BITUMAT B2 is much safer than welding with an open flame. The weld strength is significantly better and the single step process makes welding more economical.

Triac-Drive-AT

More consistent and up to three times faster than manual welding
Unique semiautomatic welding tool
Automatic welding in areas inaccessible to other tools
With welding guide, inside nozzle or outside nozzle, the unit is suitable for all roofing applications and other areas of use

The unique, semiautomatic welding tool. The flexible concept makes the TRIAC DRIVE AT an all-around tool that is universal in use.

Triac-Drive-AT with guiding help

More consistent and up to three times faster than manual welding
Unique semiautomatic welding tool
Automatic welding in areas inaccessible to other tools

The unique, semiautomatic welding tool. The flexible concept makes the TRIAC DRIVE AT an all-around tool that is universal in use.

Uniroof ST

The new UNIROOF AT/ST roof welder is your flexible partner for welding thermoplastic roofing membranes on flat or pitched roofs (up to 30°). Thanks to its slim design and construction, as well as the movable transport axle (patent pending), converting of the machine is no longer needed. Now, you can effortlessly weld close to the edge (to 100 mm ) at the parapet or on the parapet and as easily in narrow circumstances.

For specific material like EPDM/modified bitumen (e.gResitrix) and also TPO/PVC membrane

For customers who can’t afford the AT technology

Open loop control for temperature and air blower
Brush motor for blower (drive motor brushless)
Potentiometer/knobs
230V/16A

Hot Air Hand Tools

Electron ST

The new ELECTRON ST is a real powerhouse among Leister’s hand tools. The appearance of this tool has been modeled after the new TRIAC range. For the user, this means improved ergonomics and, as a result, the ability to work in more comfort. Existing ELECTRON nozzles fit the new model.

Triac AT

The TRIAC AT is an intelligent hot-air hand tool for welding and shrinking plastics that is suitable for on-site use. It is designed for the needs of even the most demanding professional. Every tool undergoes stringent quality checks prior to leaving the factory in Switzerland. This high-quality hot-air hand tool is equipped for all situations. Its universal areas of application are virtually unlimited. The TRIAC AT will continue to prove its merit in any weather condition and is just as effective outside as it is indoors – all during continuous operation.

Triac ST

Handiness, reliability and versatility are the key arguments in favor of the TRIAC ST. Its two-component handle gives users a perfect grip, while the low weight of less than 1 kg ensures an optimum weight balance. The innovative motor and turbine design, combined with the heating element familiar from the TRIAC AT, enhance the value even more. More than 80 nozzles fit onto the TRIAC ST; these are also compatible with the TRIAC AT and TRIAC S.

Testing Instruments

Coupon Cutter

The Leister COUPON CUTTER is a weld test punch proven on building sites for peel, shear and tensile testing. It is ideal in combination with one of the two tensile test tools EXAMO 300 USB or EXAMO 600 USB. That gives you perfect control over the quality of the welded membrane liners at all times. The strong leverage eff ect ensures easy handling and perfect cutting results.

Examo USB

EXAMO performs tests at the construction site – quick, reliable and uncomplicated.
