5.8.7

Pulses, function sequences

NOTE

The function sequences in pulses basically behave in the same way as in standard
welding, but during the main current phase there is a continual switching back and forth
between the pulse and pause currents at the relevant times.

The pulse function can also be deactivated if necessary during the upslope and
downslope phases "See 5.8.4 Expert menu (TIG) chapter"
