Tap UP (or Range DOWN) indicator (

t-UP) – Shown at the end of a weld sequence if the
weld control is unable to compensate and maintain the programmed CURRENT. In this
case, moving the tap selector, if exists, to a higher setting will allow the control to maintain
the current constant. If machine is already at the highest tap setting, the maximum current
range of machine is much lower than the programmed range in

8.3.1 USING CONSTANT CURRENT PROCESS OUTPUTS
The EN1001, while in any CONSTANT CURRENT mode, can be programmed to always provide
a weld current readout at the end of any weld sequence, no matter what is shown on display
before beginning of sequence. Several CONSTANT CURRENT PROCESS OUTPUTS function
as defined in Section 5.4.7 and can be programmed to function as explained below.
To obtain an End of Sequence Readout, find

12. While in CONSTANT CURRENT mode, control will measure the value
of current maintained during the weld and show this value on DATA display at the end of
the sequence. If limit window is being monitored for HI/LO range, the value shown on the
display will be the CURRENT maintained by control if it can maintain this value. If the
control cannot maintain the set CURRENT value, the control will flash
