Your best choice on Resistance Welding and Alloy of Copper 


In Masinsa we have completed 21 years of constant effort to offer our customers products and services of the highest quality.

During the most recent years, we have reached agreements with important companies of the Resistance Welding market in North America to distribute their standard products in Mexico.

Following this line, recently we joined as members of AWS (American Welding Society) and RWMA (Resistance Welding Manufacturing Alliance), which allows us access to a great amount of information and accumulated support from the long expertise of all member companies.

Furthermore, we keep on fabricating special products in our two manufacturing plants, one in Mexico City an the other at Saltillo, Coahuila

If your company has a need for resistance welding consumables or accessories, give us the opportunity to serve you and prove that we are a better option.
