- The menus are accessible and can be modified. Ex :
- JOB 5, out of adjustment, SAVE IN / JOB 5, the JOB is overwritten with the new parameters and taken into account.
- JOB 5, out of adjustment, SAVE IN / JOB non-existent, it will be taken into account in the current q.L. if and only if this new JOB X is lower than the number
of the JOB entered.
- The JOB reminder is inactive when navigating through the welding cycle or one of the two menus.
(*) A JOB is disturbed by HMI action (welding parameter, JOB recall...), welding is allowed with the new settings. If a JOB recall is performed, then the first
JOB in the series is recalled.
VOLTAGE REDUCING DEVICE (VRD)
The voltage reducing device (or VRD) reduces the assigned no-load voltage to a level not exceeding 35V when the resistance of the external welding circuit
exceeds 200Ω The reaction time is less than 300ms.
By default, the voltage reducer device is disabled. In order to activate it, the user must open the product and follow the following procedure:
- Switch off and disconnect the product from the network
- Set the switches as below:
