8.4.1 TORCH LINER CLEANING
1. Disconnect the power source from the input power socket.
2. Disconnect the torch assembly from the unit
3. Remove the wire from the torch wire-liner by pulling the wire out from the torch wire-
liner and laying it neatly for re-installation at the end of this procedure.
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.
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.
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
