There are two main types of welded plugs, internal and external. Internal welded plug ends are designed for use on bus pipes, they are used to minimize electrostatic losses and to prevent the nesting of birds. The welding plugs are usually made of aluminum alloy and are the end cap for aluminum tube. They are driven into place for a secure fit, doing so seals out moisture, reduces electrostatic loss, and eliminates hazards created by nesting birds. For correct installation, make sure that it is free of dirt, grease, oil, and moisture. Slide the conductor into the cavity, until it is almost in the rear cavity. Then, welding or other part installation can be started. Let us know what we can do here at Northern Power Equipment to help answer any of your questions or concerns.
