Thanks to its interactive functions, the myLeister app expands your Leister device into an intelligent tool and offers you continuous added value through ongoing further development. Devices Register all of your Leister equipment purchased after January 2012* and you will receive a valuable overview of your Leister device fleet. You can also "connect" your connectable Leister devices to use other exciting functions such as Live View, LQS, or My Recipes. Assign each device its own inventory number or change the basic setting of your connectable Leister equipment via your mobile device in your own language. A total of 14 languages are available. The following Leister devices can currently be coupled with the myLeister app: - COMET HS - COMET 700 - GEOSTAR G5/G7 LQS - TWINNY T5/T7 - UNIROOF 700 - WELDPLAST 600/605 - VARIMAT 500/700 - SOLANO AT Further devices will follow. *A serial number on the device nameplate is required for this. LiveView View the status of the connected Leister device in real time on your mobile device during the welding operation. Recipes Find test welding recipes (welding parameters) for almost every Leister device* or manage the own recipes of your connectable Leister device. Send your own recipes to all Leister devices you have coupled (assuming the same device type). *if available, excluding civil engineering. NFC Use NFC (Near Field Communication) to transfer the basic settings from one Leister device to another*. *Leister-SOLANO only. Not available on iOS devices due to limitations of the operating system. LQS (Leister Quality System) During welding, record the relevant welding parameters and use them for evaluation. Then export a PDF report or send it by e-mail. Tools The Tools contains other useful functions: Power Cord Checker By calculating the maximum cable length and the cable cross section, we help you to simply and reliably reduce disturbances in your work process. Unit Converter If you want to quickly convert Celsius (°C) to Farenheit (°F) or Kelvin (°K), or convert Newton (N) to pound-force, this tool is the answer. Process Heat Formulas Various formulas will help you to evaluate the most suitable air heater or blower for you and your application. Demo mode Experience the added value of the myLeister app before you register through the integrated demo mode. Start the demo mode in your settings and use the available demo data to test new functions. Settings Personalize the main menu to your individual needs.
