Functional characteristics

TIG welding

Item No.: 099-004877-EWM01

5.3.7

TIG pulses, function sequences

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.

5.3.7.1

TIG pulses – non-latched operation
