WIRE SPEED CONTROL (Figure 3-1) The WIRE SPEED Control provides a means of determining the rate at which welding wire will be fed into the weld. Rotating the WIRE SPEED Control in a clockwise direction will increase the rate of the wire feed. When the WIRE SPEED Control is set at 0, wire will feed at a rate of 50 1PM, when set at 100, the wire will feed at a rate of 675 1PM. 3- 3.
