A Bus Assembly is basically a conductor of weld power form the weld generator to the coil holder which then goes through the coil and to the tube. Bus Assemblies are known as the intermediate power link between the welder power supply and the coil holder.
They usually consist of the copper work to transmit the power and a duct work box surrounding the copper to protect operating personal and help contain the RF field. EHE manufactures all types of Bus Assemblies to fit most welders, from simple standard design to special applications designed to fit in difficult environments.
We can also supply assemblies with enhanced features. One of these is a positive air pressure system to keep contaminants from entering the duct work and greatly reducing the chance of short circuiting. We build units with capacitors and special insulating including encapsulated nose pieces.
