- DYNAMIC ARC

○ Welding power remains constant even when the distance between electrode and workpiece

changes.

Consequences of a higher value:

•

Prevents electrode bonding; Thin gauge sheets are easily distorted.

AC FREQUENCY

○ The AC frequency is the number of inversions by DC + to DC- in a unit of time (T1) and it is

adjusted in Hertz (Hz). The reduction in the frequency value of the electric arc inversion tends to

widen its size, therefore it is advisable to use low frequencies for the welding of relatively large

thicknesses or for filling passes in multipass bevels. Conversely, in increasing the inversion fre

quency value, the arc size tends to decrease and therefore increases the concentration of the

pool and the precision of the welding. It is therefore advisable to use high values of frequency for

the welding of very thin thickness or for facings on edges of moulds.
