SYNERGIC CV VOLTAGE DISPLAY

When the voltage knob is rotated, the display will show an upper or lower bar indicating if the voltage is above or below the ideal voltage.

• Preset voltage above ideal voltage. (upper bar displayed)

• Preset voltage at ideal voltage. (no bar displayed)

• Preset voltage below ideal voltage. (lower bar displayed)

Start Procedure

The Start Procedure

control s

 

the WFS, Volts at 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.

ARC CONTROL

DESCRIPTION

PINCH EFFECT

Pinch controls the arc characte-

DESCRIPTION

 

 

Postflow Time

Adjusts the time that shielding

0 to 10 seconds

gas flows after the welding out-

 

put turns off.

 

 

 

 

Burnback:

The

burnback

time

is t he

0 to .25 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 volts for a specified

 

time

at t he 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.
