How is the wire-feed speed changed with a linear feed system?

To determine

The change in wire feed speed with liner feed system.


Liner feed systems work completely different from the standard feeding systems. It uses a small motor along with a hollow shaft. The wire is fed through the hollow portion of the shaft.

Linear feeding system does not have conventional bulky gear and roller arrangement which makes it light in weight and takes less power to operate.

In linear feed system the rollers are attached so, that it can move around the wire. Changing the roller pitch (angle) results in the change of speed by which the electrode is being fed without changing the motor speed...
