We have a 2-roll feed system normally for smaller machines, this comprises of a bottom roller with grooves in and a top pressure roller which is flat and puts pressure on wire as set by tensioners to drive wire when the rollers turn.
Also we have 4-Roll system which has two bottom rollers and two top rollers which give a more stable wire feed and is better at feeding softer alloy wires than a 2-roll system. Some wire feed units also have geared 4-roll systems which helps to regulate wire flow speed with great accuracy resulting in exceptionally smooth welds.
