Don´t overload welding cables over permissible values due to voltage losses and
heating.
Fasten the earthing press of the return current cable carefully, preferably direct
onto the piece to be welded.
The contact surface area of the press should always be as large and steady as pos-
sible. Clean the contact surface from paint and rust.
