18. Arc shaping Capabilities
Arc shaping capabilities are enhanced by improved balance control. On the left is the tungsten with a balled end, due to more time spent in the electrode positive (EP ) part of the cycle, which creates shallower penetration. On the right is the tungsten with a sharp end, due to more time spent in the electrode negative (EN) part of the cycle, which creates deeper penetration and allows faster travel speeds.
