IMPEDER

The primary function of an impeder is to increase the impedance of the parasitic current path around the inside circumference of the tube, thus diverting more of the available energy into the weld "vee". Impeders also concentrate the magnetic flux created by current in the work coil, so that a greater amount of energy is induced into the tube.
MUNGIPA ELECTRICALS is a world leader in supplying impeders and coils to the tube and pipe industry, but we are much more than that. Engineering experience is the foundation on which we have built over the last 30 years. MUNGIPA ELECTRICALS personal understand the principles of getting power transferred into tube and pipe for welding. This knowledge allows us to continue to develop innovative products. And our mission is to provide fast, reliable service for innovative products at highly competitive prices. We receive calls daily from a world wide customer base not only to supply our standard components but to assist in developing, designing, and manufacturing new products for ever increasing demands. 
From a simple stick of ferrite to complete welder bus assemblies MUNGIPA ELECTRICALS has a full range of products for welding tube, shapes, or pipe. Components range from off the shelf ferrite and impeders to component assemblies built to your drawings or engineered in house. Our in house engineering department is available to design solutions and components to meet your specific needs. We look forward to your calls for assistance in improving an existing operation or to solve a welding problem.
