GETTING STARTED
Section I: Planning for Installation
Space Requirements
We recommend that the Power Supply be installed in a well-ventilated area that is free from excessive
dust, acids, corrosive gasses, salt, and moisture. Other installation considerations are:
•
Allow sufficient clearance around both sides and the back for power and signal cable runs.
•
Allow ample workspace around the Power Supply so that it will not be jostled or struck while
welding.
•
The work surface must be level, stable, free from vibration, and capable of supporting the
combined weight of the total welding system.
•
The Power Supply must be far enough from the weld head to avoid contact with weld splash.
•
Assure that there are no sources of high-frequency energy close by.

The power cable for the 230-volt version of the Power Supply the (Model UB25/230) is not supplied with
a wall connector due to the variety of connectors used by different countries. You will need to install the
appropriate connector to the Power Supply power cable before installation and setup. The input power
wiring diagram is in
Appendix B, Electrical and Data Connectors.
If you will require compressed air and cooling water service for the weld head, please refer to the weld
head manufacturer’s user’s manual for service specifications.
