Earth connection

Use a separate grounding (earthing) cable for each power source:
Separate grounding (earthing) cable
Grounding (earthing) cable laid in a loop
Welding circuit IMPORTANT! The welding circuit inductivity L and the welding circuit resistance r must be
inductivity L, calibrated separately for each power source and for each twin welding process.
