pulse welding
To use the pulse welding feature, press the PULSE button so that the ON
indicator is lit. Specify the desired welding current average (A) and pulse
time (s). The machine will set the remaining pulse values automatically.
For small welding current values, the chronological pulse ratio is 35% and
the pause current’s share of the pulse current is 35 %. The percentages are
slightly altered if the welding current average rises above 145 A.
