CHAPTER 1
DESCRIPTION
Section I. Introduction
Features
The
UB25 Linear DC Welding Control
is a Resistance Welding Power Supply. For the rest of this
manual, the UB25 will be referred to simply as the
Power Supply
. The Power Supply has the following
features:
•
Programming of time in 10 µsec increments (minimum) provides shorter weld times, less part
deformation, longer electrode life, and greater weld strength with more part ductility.
•
Built-in Liquid Crystal Display (LCD) shows a graphical "trace" of weld current, voltage, power
and resistance, plus alphanumeric peak and average values.
•
Up to 99 individual Weld Schedules (sometimes referred to as
weld profiles
) can be programmed
and stored. Weld schedules can be used individually or in sequence with others using the "chain
schedules" function. You can also use schedule #00 as a "scratch pad" for developing schedules.
•
Easy-to-set limits establish process window for acceptable quality.
•
Weld limits and user programmable relays can be used in conjunction with visual and audible
signals for operators and automation interface.
•
Active Part Conditioning (APC) compensates for varying part conditions and oxide layers.
•
Rear-mounted RS-232 and RS-485 connectors allow for remote programming, weld schedule
selection, and data logging for SPC purposes.
•
Calibration traceable to NIST standards.
•
Password protection provides process security.
