Removing Wire-Feed Rollers - ESAB EMP 285ic 1ph Instruction Manual

6.11.1

REMOVING WIRE-FEED ROLLERS

1. If new rollers are being installed select the correct size and type (Steel or aluminum)
for wire being installed (See Appendix C).
2. Disconnect the electrical power source from the unit.
3. Open the cover on the wire-bobbin side of the EMP unit.
4. Release the Tensioning Arm by pulling tension knob up out of its detent and rotating
it toward you (see (1) in Figure 6-26). Since the wire-feed pressure must be
disturbed to release this arm, the tension on the rollers will have to be re-adjusted in
a later step. The Tensioning Arm (2) is spring-loaded. It will pop-up when the Tension
Knob in the previous step is rotated out-of-the-way.
