Page 32: What's Slow Feeder Speed With Lift Arc
What is slow fed speed with lift arc So as to obtain stable lift arc at beginning, wire-fed speed will be slower.This calls slow wire-fed control, the slow speed calls slow wire-fed speed. What is delay buring When finish welding , even if switch off torch , as inertia from wire-fed machine, the action of wire-fed can not stop at once, so wire will come out of torch continuely.This will be caused stick to work-piece and make problem at next lift arc. -
