Laminated Shunts

Our shunts are customized by design, each shunt is hand made for you by our skilled craftsmen. Please note each shunt must be individually specified to fit your machine. Please supply a sketch of your shunt with each quotation request. We will be glad to help with your sketch should you have any questions. 

  • There are two different types of shunt finishes. 
    • Press welded style
    • Clipped and riveted style

For resistance welding, we always recommend clipped and riveted. In form, fit, and function press welded and riveted shunts act identical. Some applications in may require the press welded shunts, in our experance it will not affect your resistance welder.

$$ Pressed and welded shunts are more expensive than clipped and riveted. $$

Standard:  Your laminated shunt will be hand wound and formed as well as formed with cut laminations.

Upon request: When the laminations are not cut, but continue around the ends of the shunt without interruption, the current may also flow around the ends. This results in a improved distribution of current and a more even distribution of heat throughout the entire shunt. Both methods of shunt formation are utilized depending on the size and nature of the shunt being designed. 

The standard shunt is made from .005" copper laminations but .003" and .010" are available upon request.

To order you need to determine:

  1. Shunt type (shape)
  2. Lamination leaf thickness (each; i.e. .005, .010) 
  3. Total shunt thickness (laminations only)
  4. Shunt width 
  5. Shunt length (outside length) 
  6. Hole diameter - ID 
  7. Hole pattern and number of holes 
  8. Hole location from shunt end

Shunts are normally supplied with their ends secured by riveted copper clips, and are made from high grade copper.

Shunt Types and how to measure them correctly

LetterStyleMeasurements
F Straight Shunt Overall length is measured from end to end.
L&V L Shaped Shunt Overall length is measured along the outer edge, end to end.
C C Shaped Shunt Overall length is measured from end to end along the outside edge of the shunt. You also need to specify the outer edge dimension accross the open face.
J J Shaped Shunt Overall length is measured from end to end along the outside edge of the shunt. You also need to specify the outer edge dimension accross the open face. Add the distance offset between the two shunt faces.
