welding
Select the manual metal arc welding operating mode by pressing the operating 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 selection dial to set the welding current
The set value is immediately applied.
Adjust other parameters in the Setup menu if necessary
(Details in the "Setup Settings" chapter from page 76)
NOTE!
All parameter set values that are set using the selection dial are saved until their
next alteration.
This applies even if the power source is switched off and on again.

Welding with Cel
Electrodes
IMPORTANT! To weld with Cel electrodes, the setup parameter CEL must be set to "on"
(also see page 76)!
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:
- If the amperage is too low, the parent material will not be melted enough
- If overheating occurs, there is a danger that the liquid weld pool may drip
Adjustment range: off, 0.2 - 990 Hz
Operating principle:
- 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 rap-
idly re-solidify.
