AC Square Wave
It is possible with the RAZOR200ACDC machine to adjust the frequency of the AC Square Wave output.
It means that the amount of time that it takes the AC square wave to complete a full cycle switch from
postive (+) to negative (-) can be adjusted from 20 Hz (20 times per second) to 70 Hz
Increasing frequency (Hz) causes the current to change direction more often, which means that it spends
less time per cycle in both DC electrode negative and DC electrode positive mode. By spending less time
at each polarity, the arc cone has less time to expand.
A higher frequency produces a narrower arc cone producing an arc that is tighter with more focus at the
ups requiring precise penetration.
Decreasing the frequency softens the arc and broadens the weld pool producing a wider bead, produces
good overall penetration and ideal for build up applications.
