4-Step Restart Enabled (DIP Switch 4 = ON)
Same as step 1.
Same as step 2.
3. Press and hold the TIG torch trigger when the main
part of the weld is complete. The machine will now
decrease the output current at a controlled rate
(downslope), until the Start/Crater current is
reached. This Start/Crater current can be main-
tained as long or as short as necessary.
FIGURE b.10
This sequence has an automatic restart so welding
will continue after this step. If the weld is completely
finished, use the following sequence instead of step
3 described above.
3A. Quickly press and release the TIG torch trigger.
The machine will now decrease the output cur-
rent at a controlled rate (downslope), until the
Start/Crater current is reached and the output of
the machine is turned OFF. After the arc is
turned OFF the postflow time will start.
4. Release the TIG torch trigger. The output current
will again increase (upslope) to the welding current,
like in step 2, to continue welding. When the main
part of the weld is complete go to step 3.
As shown in figure B.11, after the TIG torch trigger
is quickly pressed and released from step 3A, it is
possible to press and hold the TIG torch trigger
another time to end the downslope time and main-
tain the output current at the Start/Crater current.
When the TIG torch trigger is released the output
will again increase (upslope) to the welding current,
like in step 4, to continue welding. When the main
part of the weld is complete go to step 3.
FIGURE b.11
As shown in figure B.12, again after the TIG torch
trigger is quickly pressed and released from step
3A, it is possible to quickly press and release the
TIG torch trigger a second time to end the downs-
lope time and stop welding.
