- Gas purging performed in the MAIN MENU.
Gas pre-flow
This controls the time during which shielding gas flows before the arc is struck.
- Setting of gas pre-flow time performed in the SETTINGS MENU.
Slope up
The slope up function means that, when the TIG arc strikes, the current rises slowly to the
set value. This provides a gentler heating of the electrode, and gives the welder a chance to
position the electrode properly before the set welding current is reached.
- The setting of slope up time performed in the SETTINGS MENU.
Slope down
The slope down function in TIG welding is used to avoid the formation of crate cracking at
the end of welding. It reduces the current slowly over an adjustable period of time.
- The setting of slope down time performed in the SETTINGS MENU.
Gas post-flow
This controls the time during which shielding gas flows after the arc is extinguished.
- Setting of gas post-flow time performed in the SETTINGS MENU.
Peak pulse time
This is the length of time during which the pulse current is on during a pulse cycle.
- Setting of pulse duration time performed in the SETTINGS MENU.
Background time
This is the length of time during which the background current flows. With the pulse duration
time, it gives the total pulse cycle time.
- Setting of background time performed in the SETTINGS MENU.
Background AMP
This is the lower current value of the two currents used in pulsed current welding.
- Setting of background current performed in the SETTINGS MENU.
Peak pulse AMP
This is the higher current value of the two currents used in pulsed current welding.
Irrespective of which menu is displayed, the setting value for the pulse current can always be
changed. The value is displayed in the MAIN MENU, the SELECT MENU or the SETTINGS
MENU.
