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.

7.4

Refer to MIG torch instruction manual (0458 870 *01) for replacing standard steel torch

conduit liner with a Teflon torch conduit liner.

Disconnect the power source from the input power socket.

Disconnect the torch assembly from the unit.

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.

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.

Re-install the liner.

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.
