This wire drive system has the drive rollers located in the wire feed unit only:

The push wire drive system is characterized by having the drive rollers located within the wire feed unit, which means it pushes the welding wire from the feeder directly to the welding torch. This setup is especially effective for shorter distances, as it allows for a more consistent feed of the welding wire without the need for additional components that could complicate the feeding process.

In a push system, the feed rollers are responsible for exerting pressure on the wire, which minimizes the risk of wire kinking or binding as it travels through the conduit directly to the welding gun. This design is often preferred for certain applications where the welding equipment is stationary or where the workpiece is easily accessible.

The other wire drive systems, such as pull or dual, have different configurations that involve a combination of push and pull mechanisms or utilize multiple elements for feeding the wire, which can lead to variations in performance, especially over longer distances. Therefore, understanding the operational dynamics of a push wire drive provides insight into its versatility and efficiency in specific welding scenarios.
