5 OPERATION
NOTE!
The Output wire-guide tube must be selected to match the size that corresponds
with the wire size and type (SS or aluminum) selected for use. The other two
wire-guides are standard parts which fit all wires.
There are three wire-feed guide tubes: input wire-guide tube, center wire-guide tube and
output wire-guide tube. The input wire-guide tube and the center wire-guide tube are
standard parts for all wire types/sizes, so they are not mentioned here. This procedure
addresses the removal/installation and then adjustment of the output wire-guide tube. See
Figure 22 for the location of the tubes and their holding screws.
NOTE!
This chapter requires that the wire-feed rollers have been removed to provide access
to the wire-guides. Perform wire-feed roller removal and, later in this procedure, roller
install steps. See "Removing/Installing wire-feed rollers" section when referred in the
steps below.
1. Select and obtain the correct replacement output wire-guide (see "ROLLER &
WIRE-GUIDE SELECTION" section in Appendix).
NOTE!
Since this is based on the size and type (steel or aluminum) wire selected, it is
assumed that the wire is already-selected, obtained and available for this
procedure.
1. Center wire-guide: one size fits all.
2. Disconnect the electrical power source from the unit.
3. Open the door on the wire-bobbin side of the EMP unit.
4. Release the tensioning arm by loosening the tension knob (see (1) in Figure 5), pulling
it up out of its detent and rotating it toward you. The tensioning arm (see (2) in Figure
5) is spring-loaded. It will pop-up when the tension knob in the previous step is rotated
out-of-the-way.
