Wire Feed Speed, CC Operation (See Figure B.2 or
See Table B.2)
When Across the Arc models are operated with CC power sources, the wire feed speed changes as the arc voltage changes. When the arc voltage increases, the wire feed speed will increase; and when the arc voltage decreases, the wire feed speed will decrease.
To preset the wire feed speed on CC power sources:
1.Set the Wire Feed Mode switch inside the
2.Refer to the Figure B.2 graph for the setting for the wire feed speed knob setting. Select the horizon- tal line representing the Desired Wire Feed Speed. (See Figure B.2 arrow for 375 in/min.)
3.Select the diagonal line representing the Arc Volts. (See Figure B.2 for 29 volts.)
4.Determine the vertical line representing the CC representing the CC Wire Feed Speed setting where the above two lines cross. (See Figure B.2 arrow line for 450.) Set the
CCWFS dial setting = desired WFS x 35

Set the Wire Speed Control at 450”/min., and when welding at 29 volts the average actual speed should be approximately 375“/min.
