3.3.1 Weld Arc Parameters
Weld Arc Parameters can be adjusted.
Rotate SELECT knob until the required
parameter is highlighted RED in the top part
of the screen.
Press the SELECT knob to activate the
parameter.
Rotate SELECT knob to adjust the
parameter.
Press the SELECT knob to De-activate the
parameter.
Continue to select other parameter, or
press Right Button to EXIT.
3.3.1.1 Pre Gas
Pre Gas Flow can be set to a maximum of
10 seconds to allow gas flow before Arc start.
3.3.1.2 Start Current
While in 4 STEP latch mode the arc will start
and maintain the ignition current output until
the trigger torch is released. The START
CURRENT can be adjusted 0-100% of the
WELD CURRENT setting. Setting the START
CURRENT high can be useful for joint preheat.
3.3.1.3 Up Slope
The UP SLOPE time is the time taken for
the weld current to transition from START
CURRENT value to WELD CURRENT value.
The time can be adjusted from 0 to 10 seconds.
3.3.1.4 Welding Current
The setting for actual weld current. The
Weld Current can also be adjusted from the
main Weld menu.
3.3.1.5 Down Slope
The DOWN SLOPE time is the time taken
for the weld current to transition from the
WELDING CURRENT value to the FINAL
CURRENT value. The time can be adjusted
from 0 to 15 seconds.
3.3.1.6 Final Current
The current at the WELD can be adjusted
to a value 0-100% of WELD CURRENT
which will allow controlled finish of the weld.
The end of weld pool (Crater) can be filled.
3.3.1.7 Post Gas
The Gas Flow after the end of the weld can
be adjusted from 0 to 30 seconds. This
feature can be used to provide a gas shield
to the cooling weld pool.
3.3.1.8 Peak Current
(Pulse Mode Only)
Pulse welding allows the current to be
pulsed between two values, the frequency
and ratio can be adjusted. This feature can
be used on thin material.
For pulse TIG the peak current of the pulse
can be adjusted.
3.3.1.9 Background Current
(Pulse Mode Only)
For pulse TIG the background current of the
pulse, or the low part of the pulse can be
adjusted as from 10-90% of the Peak Current.
3.3.1.10 Frequency
(Pulse Mode Only)
The frequency of the Current Pulse can be
adjusted from 0.2 to 20 Hz.
3.3.1.11 Pulse Ratio
(Pulse Mode Only)
The Pulse ratio is the ratio of the time of the
peak current compared to the total time of
hr pulse. The ratio can be adjusted for 10-
90%. Eg, if the pulse frequency is 1Hz (one
pulse per second) and the pulse ratio was
10%, the peak current would be on for 0.1
seconds and the background current would
be on for 0.9 seconds.
