12.3 Fastening the ground clamp

Abb. 4: Correct
 Attach the ground clamp immediately be-
side the welding point so that the welding
current will not try to find its own return
path through machine parts, ball bearings
or electric circuits.
 Connect the ground clamp firmly to the
welding bench or the workpiece.
Abb. 5: Incorrect
‰ Do not place the ground clamp on the
welding machine or the gas cylinder; oth-
erwise the welding current will be carried
via the protective conductors and it will
destroy these.
