Wire / electrode dimension

The table on page 58 shows the wire / electrode dimensions that can be selected.
Selected dimensions have a great impact on the start procedure and crater filling.
When welding with other wire dimensions other than those found in the table, select
one that has a dimension close to one in the list.
− Wire / electrode dimension can be selected in the main menu.
6.4

Arc voltage

Higher arc voltage increases the arc length and produces a hotter, wider weld pool.
− The arc voltage is set in the measurement display, weld data setting menu, or fast
mode menu.
6.5

Wire feed speed

This sets the required feed speed of the filler wire in cm/minute.
− The wire feed speed is set in the measurement display, weld data setting menu, or
fast mode menu.
6.6

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.
6.7

Welding direction

Travel motion in the direction that the symbol indicates.
− Welding direction is selected in the weld data setting menu.
6.8 Flux pre−flow
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.
6.9 Gas pre−flow
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.
6.10 Air pre−flow
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.
