MINIFLOOR Drive Unit

Incredibly versatile - highest cost-benefit Ratio

- The TRIAC hot-air tool and its entire nozzle range can be used both for manual welding, as well as with the MINIFLOOR Drive unti for automatic welding. Investment is already worthwhile starting with welding lengths as short as four feet!
- The MINIFLOOR is the only automatic welder in the world that offers the possibility to connect a hot-air hand tool in the simplest manner. This enhances the fields of use for a Leister TRIAC to countless variations!
- The sophisticated technology of the drive unit and the drive-sensors enable welding directly from the wall. There is only one required joint along the weld seam, and THAT saves time!
- The 51 mm/2 inches minimum distance from the wall, ensures trouble-free welding around construction pipes and L-skirts.
- The compact, low-profile design enables continuous welding in spaces with 295 mm/12-inch minimum clearance (e.g. preassembled seat racks on public transportation like trains and buses).

Easy handling

- Weighing in at 5.3 kg/12 lbs (6.6 kg/15 lbs including a TRIAC AT and nozzle) the MINIFLOOR is a lightweight solution among comparable welders and is easily transportable.
- The quick-lock fastening system at the clamp allows for assembling / dismantling of the TRIAC in a matter of seconds. Thanks to the interchangeable inserts, older TRIAC models can be connected without a hitch.
- The individually-adjustable start-up delay of the MINIFLOOR Drive Unit enables modificiation of the startup speed according to individual needs.

Incredibly fast


Despite its lightweight design, the MINIFLOOR offers a welding speed of about 2 m/6.5 ft per minute, nearly double the speed of manual welding.
With the MINIFLOOR automatic welder the field of use of the TRIAC can be expanded to countless applications. The drive unit comes with a quick-lock fastening system at the clamp at which the TRIAC is secured. This turns your hot-air hand tool into an automatic welder in a matter of seconds.
 
The MINIFLOOR clearly increases the weld quality, facilitates work and reduces the time necessary to complete your project. Its use is worthwhile from weld lengths of 1.20 m/4 ft, and thanks to its lightweight (5.3 kg/12 lbs) design, the MINIFLOOR can be transported effortlessly.

Due to its compact height, the MINIFLOOR seamlessly welds directly from the wall, beneath obstacles with a minimum clearance of 295 mm/12 inches, and at nearly twice the speed of manual welding. The asymmetrical design allows for continuous welding around construction pipes and L-skirts. The guide can be quickly positioned into the groove whereas the guide roller runs precisely along the joint line even if preparation of the groove is imperfect.

NOVOLAS™ WS-AT RTT

Turnkey laser system for all laser welding concepts
- Extensive and self-explanatory user interface
- The rotary indexing table increases throughput and economic efficiency
- Online process monitoring integrated in the control
- Modular structure enables customer-specific adaptation

The new NOVOLAS WS-AT is now also available with a rotary indexing table (RTT). The RTT is an optional module that can be used to increase the throughput of the laser welding system. Although the NOVOLAS WS-AT remains a manual workstation with this module, the cycle time is reduced, thus increasing the throughput.

The adaptations to the WS-AT with the rotary indexing table are customer-friendly in design, yet correspond to the Machinery Directives. For example, the protection guards mounted on the sides of the tabletop are also provided with a photoelectric barrier at the front to stop the rotation of the indexing table after unauthorized operation.

The newly adapted control software of the HMI (Human Machine Interface) provides a user-friendly way to set the welding parameters. Operators are guided practically through the work steps, allowing them to easily adapt the welding parameters to the process. Online process monitoring with good-bad evaluation is also integrated in the control and can be utilized when operating the relevant modules.
