Hand cutting speeds can be much less than those obtained from Machine (Mechanized) Type applications. Hand
cutting application speeds mostly depend on operator experience. The cut quality obtained at slower speeds for a
Hand application is just as good as those obtained from a Machine application. As the cut speeds increase or de-
crease from the Machine applications the following may occur:
• If cut speed is too fast the cut may exhibit one or more of the following: Insufficient Penetration, High Speed
Dross, Poor Consumable Life, Excessive Bevel Angle.
• If cut speed is too slow the cut may exhibit one or more of the following: Main Arc Extinguishes, Slow Speed
Dross, Wandering (Unstable) Arc, Poor Consumable Life.
