About RSW

Company Overview

Resistance spot welding is a process used in the manufacturing of metal products such as doors, shelves, enclosures, automobiles and any industry that manufactures metal products. The resistance spot welding process fuses two metals together using heat and pressure. High electrical current is passed through the metals to be welded and causes a focused local fusion.  Air or hydraulic pressure is applied to the welding through electrodes.

Resistance Spot Welding Sales and Consulting LLC is dedicated to serving the industry by selling spot welding machines, parts, accessories and consumables for the industry.   Our mission is to represent and distribute quality products and machinery manufactured by world class companies.  We also import “top of the line” machines and parts from TECNA S.p.A., Bologna, Italy.  www.tecna.net.   In addition to machines and parts, we also provide consulting services to our customers.  By visiting our customer locations, we are able to evaluate welding operations, make  recommendations to increase efficiency as well as train associates on machine operation and the welding process.

Over 40 Years of Experience

Ed Narvaez has been in the sales arena of the Resistance Welding Industry for over 40 years and for the last 30 as an employee of LORS Machinery in Union, New Jersey.  The last five years of his association with LORS was as a co-owner.    In January of 2015, Ed sold his interest in the company.   He remained as a consultant with the company for six months in a sales capacity.  In June of 2015, he began his own company as a distributor for LORS and other companies associated with the industry.  In June of 2016, sadly, LORS Machinery closed their doors and went out of business after 56 years of successful operation.    Since that time, many of Ed’s customers that worked with him over the years have come to trust him and have migrated to our company as the “go to source” for their spot welding needs.

"I have worked with Ed Narvaez for over 6 years and it is a privilege to recommend him as the "go-to-guy" for resistance welding solutions.  Even though we do not work at the same company any longer, I am still learning from him as we continue to solicit his consulting advise on projects where his experience is invaluable.  I can state unequivocally that he is a person of great integrity with a wealth of experience in the industry."
