As with any work area, make sure safety glasses with
side shields are worn when handling or changing wire or
clipping wire off at the spool or at the end of the torch.
hold onto the wire coming off the spool with one hand
before clipping. Serious eye injury can result due to the
resilience of the wire which can quickly unravel, or a cut
C. Feed the wire from the spool through the inlet guide,
across the drive roll grooves and center guide into the
outlet guide and NAS connection tube.
Make sure that the proper “outlet guide tube” is inserted into
the front-panel gun fitting for the size and type of wire being
used, see Table for wire feed accessories.
To ensure proper wire feeding, it is important that the wire be
kept clean and that the drive rolls be periodi cally cleaned of
any chips or scale that might be carried into the gun liner.
D. Lower pressure roll assembly and secure. Turn the power
