6 CONTROL PANEL
2-stroke
In 2-stroke mode, press the TIG torch trigger switch (1) to start the shielding gas
flow and iniate the arc. The current slopes up to the set current value. Release
the trigger switch (2) to start to slope down the current and terminate the arc.
The shielding gas will continue to flow in order to protect the weld and the
tungsten electrode.
A = Gas pre flow
B = Slope up
C = Slope down
D = Gas post flow
4-stroke
In 4-stroke mode, press the TIG torch trigger switch (1) to start shielding gas
flow and initiate the arc at a pilot level. Release the trigger switch (2) to slope up
the current to the set current value. To stop the welding, press the trigger switch
again (3). The current will slope down to the pilot level again. Release the trigger
switch (4) to terminate the arc. The shielding gas will continue to flow in order to
protect the weld and the tungsten electrode.
A = Gas pre flow
B = Slope up
C = Slope down
D = Gas post flow
Gas pre flow
The gas pre flow function controls the time during which shielding gas flows
before the arc is initiated.
Gas post flow
The gas post flow function controls the time during which shielding gas flows
after the arc is terminated.
Slope up
The slope up function is used to control the time of the current increase in the
weld initiation process to avoid any possible damage to the tungsten electrode.
