what is the function of wire feeder in mig mag welding
Gas metal arc welding 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),[12] but feed rates for semiautomatic GMAW typically range from 2 to 10 m/min (75 – 400 in/min).[13]
Ethyl methanesulfonate EMS is often used in genetics as a mutagen. Mutations induced by EMS can then be studied in genetic screens or other assays.
