NOTE!
Due to the reduced setting options (synchronisation), we recommend shielding gas-
es with a low active proportion of shielding gas, e.
g. 96% argon/4% oxygen or 90% argon/10% CO2. This results in less spattering and, in
turn, considerably less wear.
Earth connection
Use a separate grounding (earthing) cable for each power source:

Welding circuit
The welding circuit inductivity L and the welding circuit resistance r must be calibrated sep-
inductivity L,
arately for each power source for the "Drive EasyTwin" process.
