PREFLOW TIME

DESCRIPTION

 

 

0 - 10 seconds

Adjusts the time that shielding

 

gas flows after the trigger is

 

pulled and prior to feeding wire.

RUN-IN WFS:

 

Off, 50 to150 in/min.

Run-in sets the wire feed

 

speed from the time the trigger

 

is pulled until an arc is estab-

 

lished.

Start Procedure

The Start Procedure controls

 

the WFS. Trim at a specified

 

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.

PULSE FREQUENCY: (Low)-10.0 to (High)+10.0

PULSE-ON-PULSE FREQ.MODULATION (Low)-10.0 to (High)+10.0

DESCRIPTION

For Pulse modes, Arc Control changes the pulsing frequency. When the frequency changes, the Power Wave system auto- matically adjusts the back- ground current to maintain a similar heat input into the weld. Low frequencies give more con- trol over the puddle and high frequencies minimize spatter.

For Pulse -On-Pulse modes, Arc controls changes the frequ- ency modulation. The freque- -ncy modulation controls the spacing of the ripples in the weld. Use low values for slow travel speeds and wide welds, and high values for fast travel speeds and narrower welds.

Postflow Time:

Adjusts the time that shielding

0 to 10 seconds

gas flows after the welding out-

 

put turns off.

Burnback: 0 to .25

The burnback time is the

Seconds

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.

Crater Procedure

Crater Procedure controls the

 

WFS and Trim 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.
