Overview

Our Welding Machine Relay has a beautiful appearance and adopts a high-quality shell with high strength, high temperature resistance, corrosion resistance and good flame retardancy. Silver alloy contact has good conductivity and long service life. Reliable pull in, which can effectively reduce open circuit and short circuit. We focus on the production of relays for many years, fully automated production equipment and professional R & D personnel to escort the quality.

Our Welding Machine Relay has authoritative certification and reliable quality, which has achieved our good reputation in the industry today. It has 180 degree insulation grade enamelled wire, which will not age when powered on for a long time. The silver alloy contact is impact resistant, high voltage resistant, and does not adhere to excessive current. The nylon shell is resistant to high temperature and can be carried outdoors and indoors.
