TIG PULSATING WELDING WITH
CYCLE FUNCTION ON
Two different levels of pulsating current
(I and I ) can be used for welding with

this function. Here also welding can be
done in the two ways ON PULSE and
EASY PULSE.
It is also necessary to set the 2
PEAK CURRENT (I2p) (apart from the
pulsating parameters Ib, Ip, f) with the
CYCLE function on. The other 2
pulsating parameters (BASIC CUR-
RENT I and FREQUENCY f) are

obtained in synergy. FREQUENCY
remains constant while the 2
BASIC CURRENT (I ) is in proportion to
2b
