PATON ProTIG AC/DC TIG/MMA - 12 -
- Іzk – ending current
- Вр – pulse polarity balance
- Fр – pulse frequency
- Ip – lower pulse welding current
When welding with alternating current, the cyclogram becomes more complicated,
and alternating current parameters are added.
- В – polarity balance.
- F – welding current frequency. In handheld welding machines, it is usually
adjustable from 20Hz to 200Hz.
The AC frequency can be increased or decreased within acceptable limits. This
setting allows the welder to provide more control of the arc by focusing the arc
across the width so that welding in hard-to-reach places is possible. It is used as well
for welding thin materials.
