<P> The wire feed unit supplies the electrode to the work , driving it through the conduit and on to the contact tip . Most models provide the wire at a constant feed rate , but more advanced machines can vary the feed rate in response to the arc length and voltage . Some wire feeders can reach feed rates as high as 30.5 m / min ( 1200 in / min ) , but feed rates for semiautomatic GMAW typically range from 2 to 10 m / min ( 75 -- 400 in / min ) . </P>
