key to enter the squeeze time before the weld. Use the numeric
keypad to enter the time or use the ▲▼ arrows. Enter a time between 0 and
999
milliseconds.
3.
Press the
PULSE 1 UPSLOPE
key to enter the amount of time for the Weld Pulse 1
upslope. Use the numeric keypad or the ▲▼
arrows to enter the time. Enter a time
between 0 and 99 milliseconds. A good starting point is 5 milliseconds.
4.
Press the PULSE 1 WELD key to highlight the bottom line of the LCD to enter the weld
time. Use the numeric keypad to enter the time or use the ▲▼
arrows. Enter a time
between 0 and 99 milliseconds.
5.
Press the PULSE 1 WELD key again to highlight the middle line of the LCD to enter weld
energy. Use the numeric keypad to enter the energy level or use the ▲▼
arrows. The
Power Supply output ranges are:
• Current: from 0.1 → 2.4 kA
• Voltage: 0.2 → 9.999 V
• Power: 0.05 → 9.999 kW
6.
Perform one of the following:
•
From the CONTROL keys section on the front panel, press the kA key to program
current as the feedback mode.
•
From the CONTROL keys section on the front panel, press the V key to program
voltage as the feedback mode.
•
From the CONTROL keys section on the front panel, press the kW key to program
power as the feedback mode.
7.
Press the PULSE 1 DOWNSLOPE key to enter the amount of time for the Weld Pulse 1
downslope. Use the numeric keypad or the ▲▼
arrows to enter the time. Enter a time
between 0 and 99 milliseconds. A good starting point is 5 milliseconds.
Note that in
combo mode when the unit reaches a constant current, any time programmed in this
segment will be added to the weld at the constant current level.
