TIPS
• This function is available when "DC WAVE PULSE" or "AC WAVE PULSE" is selected by the
WELDING METHOD key.
• Wave pattern of the welding bead varies depending on the type of welding material, travel
speed, and the heat input during welding.
The welding materials such as a mild steel and SUS do not make wave patterns, because
they spend much time to coagulate.
• The blowhole reduction effect is related to the molten material vibration.
When the molten pool is large, the vibration becomes large and has a good effect, but if it is
small, the vibration becomes small and has no effect.
The amount of molten material is related to the bead size. When weld is performed using a
thick bead, the effect becomes large.
• This effect is not for disappearing blowholes in all welding materials such as very thick
metalizing plating, a steel product containing lots of oils, and cast metal.
• When using annealed wire, bead surface may blacken somewhat if shorting occurs
frequently during the welding operation.
