Press selection button, the LED above will light up in
turn
Relative LED lights up, Current display will show
parameters accordingly. Pre-set value can be changed by
parameter adjustment knob. See
”factory stored
programs and list of parameters
” for parameters range.
In the stick mode
LED lights up, pre-set
valuedisabled if connected to remote command, pre-set
current will be set through remote command
.
Note: when the time of short circuit between
electrode and work piece exceeds 5S, output will be
limited to 20A until electode disconnects with work
piece. Once disconnected, the machine will return to
normal welding state.
Lift TIG (GTAW welding)
To select Lift TIG welding:
Action
Visualization
Press MODE several times until the LED above lights up
When the mode button is in the Lift TIG position, the stick
welding functions are disabled and the machine is ready
for Lift TIG welding.
Simple operation procedures for lift TIG is as follows
：
1. Let ceramic nozzle on TIG torch lean against
workpiece;
2. Trigger the torch to make the machine output;
3. Rock the tungsten down to touch the workpiece,
then lift the tungsten slowly.If the arc starting is
ok, then the welding can be operated normally.
4. If the arc starting fails, then repeat the steps
above.
HF TIG (GTAW welding)
To select HF TIG welding:
Action
Visualization
Press MODE several times until the LED above lights up
When the mode button is in HF TIG position, the stick
welding functions are disabled and the machine is ready
for HF TIG welding. During the HF TIG mode, the TIG
arc is started by HF without pressing the electrode on the
work piece. The HF used for starting the TIG arc will
remain on for 5 seconds; if the arc is not started in this
time limit, the trigger sequence must be restarted.
HF Spot TIG (GTAW welding)
To select Spot TIG welding:
Action
Visualization
Press MODE several times until the LED above lights up
When the mode button is in Spot TIG position, the
machine is ready for Spot TIG welding.

In HF Spot TIG mode, the arc is generated by high-
frequency generator without touching the workpiece.
There are no upslope and downslope time, the trigger
and th e spot setting time together decide the welding
time.If the trigger is less than spot setting time, the
welding time depends on trigger time; otherwise, the
welding time is equal to the setting time.
HF Spot TIG only run in the 2-step mode.

In the TIG welding modes, this function controls the
shielding gas Preflow time. In Stick welding mode,
this is not used.
