Welding In Energy Mode - Branson 900M Series Manual

c. Welding in Energy Mode
After performing a weld in Time Mode, press the
ENERGY
key, and note the value
displayed for Weld Energy in the upper numeric display. You need this value to set the
upper and lower energy limits, since the limits set must be higher and lower than this
value. Develop a useful range of ± Energy values by welding several pieces. After each
weld, press
ENERGY
and record the value.
Figure 4-8 illustrates the weld cycle procedure and options for Energy mode. The
STATUS
display will show current status messages throughout the setup procedure.
