6.9 Travel speed
Travel speed indicates the required speed (cm/min) at which a column and boom or trolley is
to move.
• The travel speed is set in the measurement display, weld data setting menu, or fast mode
menu.
6.10 Welding direction
Travel motion in the direction that the symbol indicates.
• Welding direction is selected in the weld data setting menu.
6.11 AC frequency
(applies only to Aristo 1000 power source)
AC frequency refers to the number of oscillations per second through the zero level.
• AC frequency is selected in the weld data setting menu.
6.12 AC balance
(applies only to Aristo 1000 power source)
AC balance is the relationship between positive (+) and negative (-) pulses. The value that is
set indicates the percentage size of the period that is the positive section.
• AC balance is selected in the weld data setting menu.
6.13 AC offset
(applies only to Aristo 1000 power source)
With AC offset the AC level is offset positively or negatively in relation to the zero level.
• AC offset is selected in the weld data setting menu.
6.14 Flux pre-flow (SAW)
This controls the time during which flux flows before the arc is struck.
• Flux pre-flow is set in the weld data setting menu under start data.
6.15 Gas pre-flow (GMAW)
This controls the time during which shielding gas flows before the arc is struck.
• Gas pre-flow is set in the weld data setting menu under start data.
6.16 Air pre-flow (Gouging)
This controls the time during which air flows before the arc is struck.
• Air pre-flow is set in the weld data setting menu under start data.
6.17 Start type
There are two options for start type:
• Direct start, means that the travel speed starts when the arc is struck.
• Scrape start, means that the travel speed starts at the same time as wire feed.
• Start type is selected in the weld data setting menu under start data.
