LQS - Leister Quality System

The Leister Quality System (LQS) allows you to compile full quality documentation for all aspects of your welding work. You can document every welding seam as a table, graphic or even with GPS coordinates. The GEOSTAR G7 / G5 LQS provides all the advantages of state-of-the-art technology. It really stands out from the crowd - helping you to win over your client.

Pinpoint precision

By activating the GPS function, you can assign the welding seams precisely to the relevant location (GPS or GLONASS format).

Data evaluation on mobile devices

The data is evaluated digitally via the LQS app. This app can be downloaded free of charge from the Windows or Android Store. The LQS menus are extremely easy to navigate and are adapted to users' needs.

Data cloud

The data cloud opens up lots of extra possibilities:

Cloud function can be switched on/off
External data backup
Unit management
User management
Decentralized access to the welding data, e.g., from back office

Wireless data transfer

After the welding process, the data can be transferred conveniently via WiFi. The transfer process only takes a few seconds.

Welding report

The LQS app can be used to produce records in all standard forms:

DVS report
Tables and Graphics
PDF and CVS format
