The revolutionary UNIROOF 700 automatic roof welding machine, developed at Leister Technologies AG in Switzerland, effortlessly welds thermoplastic membranes on flat and inclined roofs (up to 30 degrees). The UNIROOF 700 has raised the bar in quality assurance across the roofing industry with its one-of-a-kind features. This includes the Leister Quality System (LQS), Monitored Welding Assistant, Recipe Management and more.

LQS is the advanced technology that gives contractors complete control of key welding parameters (speed, temperature and air volume) while documenting the welding process as an auto-generated data report. This service is referred to as, "LQS Roofing" and can be used via the myLeister app.

Documented Welding Data Report 

LQS records data from each welded seam and transfers information to a mobile device utilizing the myLeister app. Users synchronize the data to a cloud-based account where the report containing key welding data can be reviewed, saved and shared as a PDF or CSV file. This allows contractors the opportunity to further validate the quality of their workmanship, setting them apart from their competition and establishing a new standard in quality assurance across the industry.

Monitored Welding Assistant for Increased Quality

The Monitored Welding Assistant increases quality assurance in real-time: The electronic assistant instantaneously issues an acoustic warning sound and the digital display flashes in bright red if the actual welding parameters deviate from the set welding parameters. This feature allows the operator to take immediate corrective action, which includes weld quality inspection, checking machine operating status and ensuring proper welding conditions. As an additional protective measure, the available Stop Device on Alert feature will automatically initiate machine shut down if corrective actions are not taken.

Welding Recipe Management

In addition to the factory pre-set parameters available in the UNIROOF 700 menu, owners can create, store and transfer custom welding parameter recipes from within the myLeister app. Depending on material and ambient conditions, recipes can be easily accessed and changed from the display menu. After selection, Leister recommends performing test welds to verify weld quality.
