When the arc ignites, the wire feed speed

is automatically switched to the normal

user-set speed. The Creep start function

is always on.

Welding function that starts the shielding

gas flow before the arc ignites. This

ensures that the metal does not come

Used for all metals, but especially for

stainless steel, aluminum and titanium.

Welding function that continues the

shielding gas flow after the arc has extin-

guished. This ensures that the hot weld

does not come into contact with air after

the arc is extinguished, protecting the

weld and also the electrode. Used for all

When welding with high power, a crater

is usually formed at the end of the weld.

The Crater fill function decreases the

welding power / wire feed speed at the

end of the welding job so that the crater

can be filled using a lower power level.

Crater fill duration, wire feed speed and

voltage are preset by the user. The crater

fill start level cannot be smaller than the

crater fill end level.

When the 4T timer is set to ON, releasing

the trigger during crater fill does not end

welding.

Touch Sense Ignition (TSI) delivers min-

imum spatter and stabilizes the arc imme-

diately after ignition.

The WiseFusion feature enables adaptive

arc length control, which keeps the arc

optimally short and focused. For more

information, refer to "WiseFusion feature"

on page50.

Note: For the best possible welding result

when using the pulse and MAX welding

recommend a maximum subfeeder cable

you are using a 5-meter welding gun

cases, it is possible to weld with pulse

meter subfeeder device, but a test weld is

advised.

This defines the number of days to the

next device verification.

This defines how long the weld data sum-

mary is shown after each weld.
