4-11. Sequencer Controls (DX, LX And All CE Models)
1 Sequencer Control
Press switch pad until desired pa-
rameter LED is illuminated. Se-
quencing is available only while us-
ing the TIG process, but is disabled
if a remote foot or finger control is
connected to the Remote recep-
tacle (see Section 3-6). Sequencer
parameters cannot be selected if
the Stick process (see Section 4-4)
is active.
2 Encoder Control
3 Parameter Display
Turn encoder (see Section 4-2) to
set appropriate value for active se-
quence parameter. Value selected
is displayed on the parameter dis-
play, and the LED for the corre-
sponding unit of measure (A, S) of
the active parameter will be illumi-
nated.
The Sequencer parameters are as
follows:
Initial A (Initial Amperage) - Use
control to select a starting amper-
age (1–200 amps) 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) - Use control to select 0-25
seconds of time that is needed at
the beginning of the weld.
Initial Slope t (Initial Slope Time)
Use control to select 0-25 seconds
of time that it takes to slope up/
down from initial amperage to weld
amperage. To disable, set to 0.
4 Amperage Control
Use Amperage control (see Sec-
tion 4-8) to adjust Weld Time for LX
Models only.
Weld Time (LX Models Only) -
Use control to select 0-999 sec-
onds of time that is needed for weld
sequence.
Final Slope t (Final Slope Time) -
Use control to select 0-25 seconds
of time that it takes to slope up/
down from weld amperage to final
amperage. 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) - Final
amperage (1-200 amps) is the am-
perage to which weld amperage
has sloped up/down to.
Final t (Final Time)(LX Models
Only) - Use control to select 0-25
seconds of time that is needed at
the end of the weld.
