1 Sequencer Control
Sequencing is available only while
using the TIG process, but is dis-
abled if a remote foot or finger cur-
rent control is connected to the Re-
mote receptacle while in the RMT
STD mode. Sequencer parameters
cannot be selected if the Stick pro-
cess (see Section 4-7) is active.
Press switch pad until desired pa-
rameter LED is illuminated.
2 Encoder Control
3 Ammeter
Turn encoder (see Section 4-2) to
set appropriate value for active se-
quence parameter. Value selected
is shown on the ammeter (see Sec-
tion 4-4). Also, the ammeter LED for
the corresponding unit of measure
(A, S) of the active parameter will be
illuminated.
See Section 4-16 for all Sequencer
parameter ranges.
INITIAL A (Initial Amperage) - Use
control to select a starting amper-
age that is different from the weld
amperage.
Application:
Initial Amperage can be used while
GTAW welding to assist in preheat-
ing cold material prior to depositing
filler material, or to ensure a soft
start.
INITIAL t (Initial Time)(LX Models
Only) - Press control again and turn
Encoder to select amount of time
that is needed at the beginning of
the weld.
INITIAL SLOPE t (Initial Slope
Time) Use control to select amount
of time that it takes to slope up/
down from initial amperage to weld
amperage. To disable, set to 0.
4 Amperage Switch Pad
Weld Time (LX Models Only) -
Press Amperage switch pad twice.
Set desired length of weld time.
FINAL SLOPE t (Final Slope Time)
- Use control to select amount of
time that it takes to slope up/down
from weld amperage to final amper-
age. To disable, set to 0.
Application:
Final Slope should be used while
GTAW welding materials that are
crack sensitive, and/or the operator
wants to eliminate the crater at the
end of the weld.
FINAL A (Final Amperage) - Use
control to select amperage to which
weld amperage has sloped up/
down to.
FINAL t (Final Time)(LX Models
Only) - Press control again and turn
Encoder to select amount of time
that is needed at the end of the
weld.
