6. Remove the Wire-Feed Rollers per Section 6.11.1 REMOVING WIRE-FEED ROLLERS.
7. Clean the Wire-Feed Rollers with a soft brush.
8. Clean the Pressure Rollers attached to the Tension Arm with a soft brush.
9. Clean the Input Wire-Feed Guide, the Output Wire-Feed Guide, the Center Wire-
Feed Guide by blowing compressed air (max. 5 bar) through them (see Figure 6-30).
10. Replace the Wire-Feed Rollers per Section 6.11.2 INSTALLING WIRE-FEED ROLLERS.
11. Close the Tension-Arm on to the wire in its groove on the wire-feed rollers.
12. Visually verify that the wire appears as a straight line through the entire Wire-Feed
Assembly.
13. Visually verify that the wire protrudes per specification at the torch tip and has not
been pulled into the torch head.
14. Adjust the wire-feed pressure by adjusting the tension on the wire at the Wire-Feed
Rollers by turning the Tension Knob using the procedure SETTING WIRE-FEED
PRESSURE (see Section 6.10 ).
15. Close the cover on the wire-bobbin side of the EMP unit.
CAUTION
Avoid removing the drive gear behind the left wire-feed roller. Doing so risks losing the
Woodruff key on the motor shaft. Losing this key renders the unit useless until the key is
replaced.
CAUTION
Do not loosen any of the set screws for any of the three components listed in this next step.
Loosening any one will require re-adjusting their position as performed in Section 6.12.3,
ADJUSTING WIRE GUIDES.
NOTE
Verify that the wire is in its groove and not floating out
of the groove on the roller surface.
NOTE
The Bobbin may be turned counter-clockwise to take up
any slack. Do this only AFTER step 12 because the
tension on the wire is the only force preventing the
movement of the wire at the torch tip.
