4.4 PRE WELDING GAS PURGING
This function is required for protecting the weld area against atmospheric air. According to this
function, the weld area is to be purged with protective gas before arc starting. By default, the gas
purging period
[PRE FLOW]
is 2.0 s and can be varied by the operator at his option.
The procedure for changing the values of the operational parameters of the welding unit is
described in
Section 6.1.
The procedure for changing the values of the operational parameters of the welding unit is described in
Section 6.1.
4.5 INITIAL CURRENT (PILOT ARC CURRENT) SETTING
This function facilitates the welding process with the use of a welding torch at the stage of arc
starting. The function allows the welding process to be started at low welding current, which only
supports the welding process without increasing heat input to the weld and without burning through
the workpiece. In the argon arc welding process with
TIG-4T
function, it is reasonable to heat the
weld area before welding. By default, the initial current
[Start Current]
value is 15 A.
The procedure for changing the values of the operational parameters of the welding unit is described in
Section 6.1.
4.6 LINEAR INCREASE OF WELDING CURRENT
This function provides the economic consumption of an electrode, promotes the extension of the
service life of the welding torch, and facilitates the use of the welding torch. This function prevents
the spillage of molten metal in the welding pool. Additionally, during the period [
Rise Time]
of the
linear increase of welding current, it is possible to accurately locate the welding torch in the weld
area, as the arc starting point is initially not always located in the weld area. It may be reasonably to
heat the weld area. By default, the period of linear increase of welding current is 1.0 s.
The procedure for changing the values of the operational parameters of the welding unit is described in
Section 6.1.
4.7 FUNKCJA PŁYNNEGO OPADANIA PRĄDU SPAWANIA
This function is designed for smooth welding of a welding crater, which can be formed in the
welding pool due to electromagnetic blow forces generated by the welding arc. The crater so
formed can be a source of future welding defects. By default, the period
[Fall Time]
of linear
decrease of welding current is 3.0 s and can be varied by the operator at his option.
The procedure for changing the values of the operational parameters of the welding unit is described in
Section 6.1.
4.8 FUNKCJA WYPEŁNIANIA KRATERU
This function is designed for decreasing the welding current at the end of welding. The decrease of
welding current is required for welding a crater at the end of the weld. To activate the function for
the argon arc welding process with
TIG-4T
function, press and hold the button of the welding torch
for the second time. By default, the crater welding
[Finish Current]
current is 20 A and can be
varied by the operator at his option.
The procedure for changing the values of the operational parameters of the welding unit is described in
Section 6.1.
