FLEXTEC™ 500 P OPERATION
The Flextec™ 500 P welding modes utilize the UltimArc TM Arc Control
Feature for adjusting the focus or shape of the arc. UltimArc TM Control
is adjustable from -10.0 to +10.0 with a nominal setting of 0.0.
(See Figure C.3) Increasing the UltimArc TM Control increases the pulse
frequency and background current while decreasing the peak current.
This results in a tight, stiff arc used for high speed sheet metal
welding. Decreasing the UltimArc TM Control decreases the pulse
frequency and background current while increasing the peak current.
This results in a soft arc good for out of position welding.
The UltimArc TM Arc Control can be accessed through the ArcLink
compatible wire feeder user interface.
For additional information about UltimArc Arc Controls and pulse

welding procedure Lincoln Electric publishes process documents as
informational guides on various welding procedures. Access to the
