OP LINE OF THE SCREEN
SCHEDULE: Weld schedule number, shown here as 1.
R1: Weld current rise time for Weld 1, shown here as 5 milliseconds.
W1: Weld time for Weld 1, shown here as 20 milliseconds.
CO: Cool time, shown here as 10 milliseconds.
R2: Weld current rise for Weld 2, shown here as 3 milliseconds.
W2: Weld time for Weld 2, shown here as 10 milliseconds.
B
OTTOM LINE OF THE SCREEN
I.V.W: Active feedback control mode, shown here as I (Constant Current) . The
other selections are V (Constant Voltage) and W (Constant Power).
HEAT 1: Weld current for Weld 1, shown here as 2 KW.
HEAT 2: Weld current for Weld 2, shown here as 1.5 KA
NOTE: HEAT 1 and HEAT 2 are control mode dependent. In the Constant Voltage and
Constant Power control modes, HEAT 1 and HEAT 2 will be in terms of voltage (V) and
power (KW) respectively.
The MODE key accesses the Mode Selection display screen. The Mode Selection
display screen has an extension (second) screen that appears when you press
MODE a second time. The settings that you may view or edit are as follows:
PRIMARY SCREEN
IM: Current monitor selection,
shown here as 0 (current monitor
off). Other selections are 1
(monitor Weld 1 current) and 2
(monitor Weld 2 current).
VM: Voltage monitor selection,
shown here as 0 (voltage monitor off). Other selections are 1 (monitor Weld 1
voltage) and 2 (monitor Weld 2 voltage).
