Background Current adjusts the overall heat input into
the weld. Changing the background current changes the
shape of the back bead. 100% CO
2
requires less
background current than when welding with blended
shielding gases.

Note: Range depends on the power source.
Peak Current controls the arc length, which also affects
the shape of the root. When using 100% CO
2
, the peak
current will be higher than when welding with blended
shielded gases. A longer arc length is required with CO
2
to reduce spatter.

Note: Range depends on the power source.
UltimArc™ – for pulse welding adjusts the focus or
shape of the arc. In consequence of increasing
UltimArc™ Control value the arc is tight, stiff for high
speed sheet metal welding.

Adjust range: from -10 to +10

Wire spool type S200, B300 or Readi-Reel
®
can be
installed, but the applicable adapter must be purchased.
The applicable adapter can be purchased
separately(see "Accessories" chapter).
Wire Spool Type S300 & BS300 Loading
WARNING
Turn the input power OFF at the welding power source
before installation or changing a wire spool.
Figure 21.

Turn the input power OFF.

Open the spool wire case.

Unscrew the Locking Nut [35] and remove it from the
Spindle [37].

Place the spool type S300 or BS300 [36] on the
Spindle [37] making certain the Spindle Brake Pin
[38] is put in the hole in back side of spool type S300
or SB300.
WARNING
Position the spool type S300 or SB300 so that it will
rotate in a direction when feeding so as to be de-reeled
from bottom of the spool.

Re-install the locking nut [35]. Make sure that the
locking nut is tightened.
