Periods such as WELD, WELD1,
WELD2, and TEMPER have user
programmable time base values and
weld current, voltage, or energy values.
To change the Feedback Type for any
of these weld periods, press the keypad
decimal point [.] multiple times until the
upper left-hand portion of the screen
shows the desired Feedback Type. This
example shows a WELD period of 15
ms with the weld CURRENT set to 0.5
kA.

To change the weld current, use the
vertical cursor keys [
VW
] to increase
or decrease the weld CURRENT. Note:
when holding the vertical cursor keys
down to change the weld CURRENT,
the horizontal bar representing the weld
CURRENT will not move to its new
position until the vertical cursor keys
[ ] are released. However, the weld CURRENT value displayed in the upper left-hand
corner will automatically scroll during this change process. In this example, weld CURRENT
has been increased to 0.7 kA and WELD time has been increased to 20 ms.
