Read full descriptionHide full description
The welding app must be connected to an e8 welding machine from Elaso AG. This allows the user to control and monitor the welding process. The APP guides the user trough the whole process of the welding. During welding, the current, the remaining time and the level in percent (bar graph) are displayed. The user will be alerted to the end of a weld or an error by means of a hint (e8) or vibration (smartphone). In the event of an error, the display shows which error is involved and how to proceed. Various parameters such as the mains voltage, the mains frequency, the socket resistance, the indoor and outdoor temperature are permanently displayed."
