power loss. An APC manufactured Back-UPS Pro 280 (Model BP280S) or a Back-UPS 650 (Model
BK650M) are two recommended and approved models which may be used with the WeldWise™
2400.
If your WeldWise™ 2400 has been shipped with an optional UPS, the necessary UPS software is pre-
installed. You will, however, need to calibrate the UPS once you have set up your weld monitor and
UPS. Additionally, if you would like to your WeldWise™ 2400 to remotely shut down other
WeldWise™ 2400s or devices in the event of a power loss, you will need to re-configure the UPS
settings.
Note: Please be aware that once the UPS shutdown sequence has been initiated, it will not stop until
the cycle is complete, even if power has been restored midway. To prevent improper shutdowns and
possible resulting damage to your unit(s), please allow your WeldWise™ 2400(s) to fully complete the
shutdown sequence before initiating any changes.
The following sections review how to calibrate the UPS and how to set your WeldWise™ 2400 for
remote shutdown.
