Mounting the Base Mount Electrode
The weld electrode’s mounting on industrial equipment (e.g., platen,
sub-plate, etc.) is usually a copper-to-copper contact surface that will
transfer current; therefore, both surfaces need to be clean and free from
oil, dirt, and any other contaminants.
Any contamination will increase the resistance of the joint, which in turn
causes less current to flow and, therefore, an increase in temperature
will result. A thin coating of oil from your fingers is enough to cause a
change in the resistance. For this reason, it is very important to clean
and install the copper components correctly.
Once the surfaces are cleaned, the copper components should be
installed immediately, to prevent surface oxidation which will cause a
poor connection. As long as the connection remains tight, there should
be no concern for heat buildup or loss of current at the connection. If,
however, during routine service it is discovered that the joint is loose,
then it should be completely disassembled, cleaned and reassembled.
To mount the Electrode Body on machinery or fixture, follow the steps below:
1.
Use Scotch-Brite™ to clean the
electrode’s mounting contact surface.
Ensure all pitting and oxidation on the
bottom of the weld body is removed.
Wipe the surface with a clean cloth.
2.
Use Scotch-Brite™ to clean the
surface of the platen on which the
LVDT weld body will be installed.
Wipe the surface with a clean cloth.
3.
Coat the bottom of the weld body with
