Pulse welding

Pulse welding is welding with a pulsing welding current. It is used to weld steel
pipes out-of-position or to weld thin sheet metal.
In these applications, the welding current set at the start of welding is not always
optimum for the entire welding process:
-
-
Adjustment range: off, 0.2 - 990 Hz
Operating principle:

Select the manual metal arc welding operating mode by pressing the operat-
ing mode button:
IMPORTANT! If the manual metal arc welding operating mode is selected,
the welding voltage is only available after a delay of 3 seconds.
Turn the dial to set the welding current
The set value is immediately applied.
Adjust other parameters in the Setup menu if necessary

Initiate welding process
If the amperage is too low, the base material will not be sufficiently melted
If overheating occurs, there is a danger that the liquid weld pool may drip
A low base current I-G rises steeply to the significantly higher pulse current
I-P and drops back to the base current I-G after the Duty cycle dcY time.
During pulse welding, small sections of the welding location melt quickly and
then rapidly re-solidify.
