Patented technology providing instant graphical feedback on how
Wire Feed Speed and Voltage affect the weld outcome.

How does wire feed speed affect my weld?

Wire Feed Speed – As your wire feed speed is increased the weld penetration increases, and as your wire feed speed is decreased, the weld penetration decreases. Notice the changes to the weld puddle in the image shown above.

How does voltage affect my weld?

Voltage – Arc voltage affects the arc length. At the same wire feed speed, as voltage increases, the arc length gets longer and as voltage decreases, the arc length gets shorter. The length of the arc in turn determines the width and size of the arc cone. Notice the changes to the weld puddle in the image shown above.
