(CE Nameplate)
1 Final Slope Control
Indicator light is on when Final Slope
control function is active.
Note: Final Slope control function is
inactive when Spot Time function is
active.
Use control to reduce amperage over
a set period of time (0−15 seconds) at
the end of the weld cycle when NOT
using a remote current control.
2 Final Amperage Control
Indicator light is on when Final Am-
perage control function is active.
Note: Final Amperage control func-
tion is inactive when Spot Time func-
tion is active (see Section 4-16).
Final amperage is the amperage to
which weld amperage has sloped
down to (0−100% of amperage set on
Amperage Adjust control).
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.
Note: This applies if the operator is
using an on/off only type control to
start and stop the welding process.
Note: Do not use this function with a
foot or finger amperage control.
NOTE: Function is enabled, when
LED is lit.
4-16. Spot Time Control
1 Spot Time Control
Indicator light is on when Spot Time
function is active. When Spot Time func-
tion is active, Initial Time, Initial Amper-
age, Final Slope, and Final Amperage
functions are inactive (see Section
4-13).
Used with the (GTAW) TIG Spot pro-
cess, generally with a direct current
electrode negative (DCEN) set-up.
Use control to select 0−15 seconds of
spot time.
Use Amperage Adjust control (see Sec-
tion 4-1) to set amperage.
Application:
TIG spot welding is used for joining thin-
ner materials that are in close contact
with the fusion method. A good example
would be joining coil ends.
NOTE: Function is enabled, when LED
is lit.
