NON-SYNERGIC GMAW AND FCAWWELDING

In non-synergic modes, the WFS control is similar to a

conventional CV power source where WFS and volt-

age are independent adjustments. Therefore to main-

tain the arc characteristics, the operator must adjust

the voltage to compensate for any changes made to

the WFS.

UltimArc™Control, adjusts the apparent inductance of

the wave shape. The UltimArc™Control adjustment is

similar to the “pinch” function in that it is inversely pro-

portional to inductance. Therefore, increasing

UltimArc™Control greater than 0.0 results in a crisper

arc (more spatter) while decreasing the

UltimArc™Control to less than 0.0 provides a softer

arc (less spatter).

Start Procedure

DESCRIPTION

Adjusts the time

that

shielding

gas

flowsafter the trigger is pulled

andprior to feeding wire.

Run-In sets the wire feed

speed from the time the trigger

is pulled until an arc is estab-

lished.

The Start Procedure controls

the WFS and Volts for a speci-

fied time at the beginning of

the weld. During the start time,

the machine will ramp up or

down from the Start Procedure

to the preset Welding

Procedure.

Spot Timer Adjust the time welding will

continue even if the trigger

is still pulled. This option

has no effect in 4-Step

Trigger Mode.

Crater ProcedureCrater Procedure controls the

WFS and Volts for a specified

time at the end of the weld

after the trigger is released.

During the Crater time, the

machine will ramp up or down

from the Weld Procedure to

the Crater Procedure.

Burnback: The burnback time is the

amount of time that the weld

output continues after the wire

stops feeding. It prevents the

wire from sticking in the puddle

and prepares the end of the

wire for the next arc start.

Postflow TimeAdjusts the time that shielding

gas flows after the welding out-

put turns off.
