SECTION 3
NOTE
For ALL dual schedule MMI panels, a weld
schedule can be disabled by placing the
wire feed speed knob to the minimum po-
sition or "0" (zero) position. This will elimi-
nate the accidental triggering of the Mig
gun into the alternate weld schedule.
NOTE
Arc voltage CANNOT be preset on the
digital meter. Actual arc voltage will
be displayed once welding begins.
NOTE
Dual schedule parameter switching from
the gun trigger is disabled when TRIG-
GER LOCK is turned "ON".
V. OPERATION
Two welding parameters can be preset on the Basic Dual MMI panel. The
SCHEDULE toggle switch position determines the welding schedule to be
used when the gun trigger is depressed. The welding schedules (parameters)
can be switched between schedule A & B while welding by using the "Click
Click" trigger technique. If the gun trigger is release and depressed quickly
(within .2 sec) the weld schedule will switch to the alternate schedule. This
method of welding is used for providing a hot start, crater fill or gap filling
welding parameter in addition to the standard welding parameters typically
used for the given weld application.
A. Power Source and DuraDrive Set-Up
1. Turn the power source and DuraDrive wire feeder "ON".
2. Place the power source PROCESS SELECTOR switch (if present) in
the Mig position and the MIG SELECTOR switch (if present) to the type
of Mig wire to be used. (Example - 350MPi or MTS-3500i)
3. The position the REMOTE/PANEL on the power source to the REMOTE
position.
4. Choose SCHEDULE A using the SCHEDULE SELECT toggle switch
on the Dual Schedule MMI panel and set a wire feed speed.
5. Make a weld and adjust the arc voltage and wire feed as needed for good
welding characteristics.
6. Choose SCHEDULE B using the SCHEDULE SELECT toggle switch
on the Dual Schedule MMI panel and set a wire feed speed.
7. Make a weld and adjust the arc voltage and wire feed as needed for good
welding characteristics.
8. Position the SCHEDULE SELECT toggle switch to the preferred
schedule for starting the weld.
9. While welding, the weld schedule can be changed from the Mig gun
trigger by using the "Click Click" method.
a. After starting the weld, double click the gun trigger (within .2
seconds) and the MMI will switch to the second weld schedule.
b. Switch back to the first weld schedule by double clicking the trigger
again.
