DESCRIPTION
PEAK CURRENT
Peak Current acts similar to an arc pinch
control. Peak Current sets the arc length
and promotes
current levels will cause the arc to broaden
momentarily while increasing arc length. I f
set too high, globular transfer may occur.
Setting it too low may cause instability
and wire stubbing. Best practice is to
adjust for minimum spatter and puddle
agitation.
Background Current controls the overall

heat input in the weld.

Tail out provides additional power

heat input without increasing arc length.
Often this results in faster travel speeds.
Note that as tail out increases, the peak
and/or background current may need
current
to be reduced.

Burnback: 0 to .25
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.
