EMP-unit power side maintenance
NOTE!
There are no user-serviceable parts on the power-side. In dusty environments, the
power-side should be checked periodically for any dust/debris accumulation because
of the fan forced-air cooling used on this side.
Because of the electro-static sensitive components and exposed circuit boards any
maintenance on this side should be done by an authorized ESAB service technician.

Torch liner maintenance
Refer to MIG torch instruction manual for replacing standard steel torch conduit liner with a Teflon® torch conduit liner.
8.4.1
Torch liner cleaning
1. Disconnect the electrical power source from the unit.
2. Unlock tension knob, rotate spool clockwise while holding the wire until wire is no longer in the torch. Re-secure the
wire between tensor knob and roller.
3. Disconnect the torch assembly from the unit.
4. Remove the liner from the torch hose and inspect it for damage or kinks. Clean the liner by blowing compressed air
(max. 5 bar) through the end of the liner that was mounted closest to the unit.
5. Re-install the liner as per the instructions of the MIG torch instruction manual
6. Re-install the wire through the wire-feed assembly until visible at the torch tip. Verify that the wire does correctly feed
out of the torch.
NOTE!
Excessively worn torch liners require periodic replacement. If above steps fail to re-
solve feeder issues, replace the liner as per section 5.7 Liner selection
