B-4 OPERATION B-4
2. Data Display -
The unit features a single main
digital display. The data in the display is always
accompanied by a corresponding LED light which
indicates the function being represented. This also
in-cludes a self diagnosing function which displays an
error code and a corresponding warning light.
3. Parameter Selector
The push button selector is used to scroll left to
right(or right to left) through different panel settings.
4. Indicating light of power
Turn power on, it will illuminate indicating .
5.Unit.
S -- unit of up & downslope time & pre& post flow time
% -- unit of AC balance &peak time on Hz-- unit of
pulse freq.&AC freq.

8. warning indicating light
-If the welder overheats due to blocked air flow,
high ambient air temperature, or exceeded duty
cycle, an internal thermostat will open disabling the
welding output and this yellow light will illuminate.
The cooling fans will continue to run to cool the unit
during this time. The light will go out when the unit
cools and the thermostat resets. Once the light
goes out, the machine will again become available
to weld.
-output current is too high or the machine fails.

After the arc is started the output current will be
increased from the start current to the welding
current. Both the start current and increase, or
upslope time are presettable. The default start
current is 15 amps and the default upslope time is
0.2 seconds.
2. Release the Arc Start Switch to stop welding.
The machine will now decrease the output current
at a controlled rate, or down slope time, until the
Finish current, (also commonly referred to as Crater
Current) is reached and the output of the machine is
turned OFF. Both the Down slope Time and the
Finish Current are can be preset.
After the arc is turned OFF, the gas valve will
remain open to continue the flow of the shielding
gas to the hot electrode and work piece. The
duration of this postflow shielding gas is adjusted by
the Postflow Parameter.
Possible variations of this standard sequence is
shown in (2 step diagram 2). It is possible to press
and hold the TIG torch trigger a second time during
downslope to restart. After the trigger is pressed the
output current will increase to the welding current.
This operation is shown in (2 step diagram 2).
2 STEP DIAGRAM 2
4-Step Sequence
With the 4-step Selected, the following welding
sequence will occur.
1. Press and hold the Arc Start Switch to start the
sequence.
The machine will open the gas valve to start the
flow of the shielding gas. After a 0.5 second preflow
time, to purge air from the torch hose, the output of
the machine is turned ON. At this time the arc is
started.
After the arc is started the output current will be at
the Start current. This condition can be maintained
as long or as short as necessary.
If the Start current is not necessary, do not hold the
TIG torch trigger as described at the beginning of
this step. Instead, quickly press and release the
trigger. In this condition, the machine will
automatically pass from Step 1 to Step 2 when the
arc is started.
