PULSE

DESCRIPTION

FREQUENCY:

 

 

(Low)-10.0 to

For Pulse

modes, A rc Control

(High)+10.0

changes the pulsing frequency.

 

When the frequency changes,

 

the Power Wave system auto-

 

matically

adjusts the back -

 

ground current t o maintain a

 

similar heat input into the weld.

 

Low frequencies give more con-

 

trol over the puddle and high

PULSE-ON-PULSE

frequencies minimize spatter.

For Pulse -On-Pulse modes,

FREQ.MODULATION

Arc controls changes the frequ-

(Low)-10.0 to

ency modulation. The freque-

(High)+10.0

-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.

PREFLOW TIME

DESCRIPTION

 

 

 

0 - 25.0 seconds

Adjusts the time that shielding

 

gas flows after

the trigger

is

 

pulled and prior to feeding wire.

RUN-IN WFS:

Run-in sets

the wire

feed

Off, 30 to150 in/min.

 

speed from the time the trigger

 

is pulled until an arc is estab-

 

lished.

 

 

 

Start Procedure

The Start Procedure

control s

 

the WFS. Trim a t a specified

 

time at t he beginning

of t he

 

weld. During the start time, the

 

machine will ramp up or down

 

from the Start Procedure to the

 

preset Welding Procedure.

END OPTIONS

 

 

 

 

 

Spot Timer

 

Adjust the time welding will

 

 

0 to 120.0 Seconds

 

continue even if the trigger

 

 

 

 

is still pulled. This option

 

 

 

 

 

has no effect in 4-Step

 

 

 

 

 

Trigger Mode.

 

 

 

 

 

Postflow Time:

 

Adjusts the time that shielding

 

0 to 25.0 seconds

 

gas flows after the welding out-

 

 

 

put turns off.

 

 

 

 

 

Burnback: 0 to .25

 

The

burnback

time

is t he

 

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 P rocedure

controls

the

 

 

 

WFS and Trim for a

specified

 

 

 

time

at

the end

of t he wel d

 

 

 

after

the trigger

is

released.

 

 

 

During

the Crater

time,

t he

 

 

 

machine will ramp up or down

 

 

 

from

the Weld Procedure

to

 

 

 

the Crater Procedure.
